## Technology

Lynx Kitchen uses a rotating mesh that spins at 75–314 G centrifugal force — up to 440 times stronger than the industry's passive solutions (0.71 G). Grease and liquid particles down to 0.3 µm are ejected radially, collected, and drained continuously. Lynx works closely with Camfil and uses Camfil filters to capture dry particles.

## Regulatory Compliance — Per Country

### Norway

Framework: Commercial kitchen exhaust is governed by TEK17 and the pre-accepted performance requirements in VTEK, with duct fire safety addressed through the guidance document Imkanal 2012:2 and NS-EN 16282. Lynx Kitchen is placed upstream of the duct and fan and does not alter their classification or fire resistance.

Relevance: Continuous grease separation keeps the duct clean, directly supporting Imkanal's principle of limiting combustible deposits and reducing the cleaning frequency the duct would otherwise require. Lynx Kitchen is the only documented solution that meets Avinor Oslo Airport's requirements for grease separation from kitchen ventilation, and one installation at Gardermoen runs a Lynx unit inside a Halton hood. A SINTEF research project on heat recovery directly downstream of a Lynx unit is ongoing at the same airport.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

### Sweden

Framework: Fire safety for ventilation in commercial kitchens is regulated by Boverkets byggregler (BBR), section 5:5332, supported by the guidance document Imkanal 2012:2 and Lag om skydd mot olyckor (LSO). BBR 5:5332 recognises three approved approaches to limiting fire spread from cooking equipment through the extraction system, one of which is a filtration or separation system that limits the accumulation of combustible deposits.

Relevance: Lynx Kitchen sits squarely within this approved BBR path: by continuously removing grease from the airstream, the unit limits combustible deposits in the duct as the regulation requires. This makes Lynx Kitchen a documented compliance route rather than an add-on product, and it combines naturally with downstream ozone or UV odour treatment without competing with it.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: https://www.lynxkitchen.com/docs/Datasheet_Lynx_Kitchen_250__Sweden_EN.pdf

### France

Framework: Ventilation of commercial kitchens in public buildings (ERP, grandes cuisines) is governed by the Arrêté du 25 juin 1980, chapter GC. Article GC 11 requires that exhaust fans maintain function for at least one hour in smoke at 400 °C (two hours in most modern French specifications), with fan-to-duct connections in M0 or A2-s1,d0 materials and CR 1 electrical supply. Articles GC 18 and GC 21 set cleaning obligations. The relevant product standard is NF EN 16282, and fan classification follows EN 12101-3 (F400).

Relevance: Lynx Kitchen is installed upstream of the fan and does not change the GC 11 requirements on the fan, duct, or electrical supply, which continue to be met by the existing F400 installation. The fail-open feature reinforces this: when the unit opens on a fire signal and the pressure drop falls toward zero, it does not restrict the extraction path at exactly the moment GC 11 demands maximum smoke evacuation at 400 °C. Continuous grease removal keeps the duct free of combustible deposits and significantly reduces the cleaning burden under GC 18 and GC 21.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

### Germany

Framework: Ventilation in commercial kitchens follows VDI 2052 (ventilation of commercial kitchens) and DIN 18869 for kitchen equipment, with duct and fire requirements referencing DIN EN 16282 and smoke extraction fan classification per DIN EN 12101-3. German practice typically specifies F300 or F400 fans depending on building type and risk assessment. Fire protection requirements for grease ducts follow the current Muster-Lüftungsanlagen-Richtlinie (M-LüAR).

Relevance: Lynx Kitchen is placed upstream of the fan and duct and does not alter their fire classification. Continuous self-cleaning supports the M-LüAR and VDI 2052 principle of keeping grease ducts free of combustible deposits, reducing both fire load and cleaning intervals. The fail-open feature ensures the unit does not restrict airflow to an F300 or F400 fan in a fire event.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### Spain

Framework: Ventilation in commercial kitchens is regulated by the Código Técnico de la Edificación (CTE), in particular DB-SI for fire safety and RITE for thermal installations. Grease-laden exhaust ducts must meet defined fire resistance and cleaning requirements, with smoke extraction fan classification per UNE-EN 12101-3 and kitchen ventilation components per UNE-EN 16282.

Relevance: Lynx Kitchen is installed upstream of the fan and does not change CTE DB-SI requirements on the duct or fan. Continuous grease separation keeps the duct clean and supports the DB-SI objective of limiting fire spread through the extraction system, while reducing the required cleaning frequency. The fail-open feature keeps the extraction path unrestricted in a fire event.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### Italy

Framework: Fire safety for ventilation in commercial kitchens is governed by the Codice di Prevenzione Incendi (DM 3 agosto 2015 and updates) and relevant UNI standards, with kitchen ventilation components per UNI EN 16282 and smoke extraction fan classification per UNI EN 12101-3. Grease ducts must meet fire resistance requirements and be cleaned regularly.

Relevance: Lynx Kitchen is placed upstream of the fan and duct and does not alter their fire classification. By continuously removing grease from the airstream, the unit limits combustible deposits that the Codice is designed to control, and reduces cleaning intervals. The fail-open feature ensures the unit does not restrict smoke evacuation in a fire event.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### United Kingdom and Ireland

Framework: Commercial kitchen duct systems follow BS EN 16282 and the BESA DW/172 specification for kitchen ventilation systems, with cleanliness and fire risk addressed under the cleaning standard TR/19. Smoke extraction fan classification follows BS EN 12101-3. Insurers typically require documented duct cleaning in line with TR/19 frequencies.

Relevance: Lynx Kitchen is installed upstream of the fan and does not change DW/172 requirements on the duct or fan. Continuous grease separation keeps the duct clean and directly supports the TR/19 objective, reducing both cleaning frequency and the insurance exposure that grease accumulation drives. The fail-open feature keeps the extraction path open in a fire event. Several UK ventilation specialists already use equivalent separation in airport and high-volume kitchen projects; the Gardermoen reference is directly relevant.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### Canada

Framework: Commercial kitchen exhaust follows NFPA 96 as adopted through provincial fire and building codes, plus the National Building Code of Canada and provincial energy codes. A grease removal device not integral to a listed hood must carry a CAN/ULC-S649 listing to be code-compliant. In Quebec, the Construction Code Chapter I.1 (in force December 2021) and converging NECB requirements make heat recovery effectively mandatory in new commercial kitchens above 5,000 CFM.

Relevance: Lynx Kitchen functions as a grease removal device in the airstream. CAN/ULC-S649 listing is being established with our Canadian partner; until listing is in place the unit is specified as a supplementary separation stage rather than the code-required grease removal device. The key design advantage is heat recovery: clean air off the Lynx unit lets a conventional run-around coil or plate exchanger sit directly downstream without the fouling that normally makes heat recovery in kitchen exhaust impractical, supporting Chapter I.1 and NECB compliance and qualifying for utility rebate programmes. The fail-open feature keeps the extraction path open in a fire event.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h (approximately 500 CFM), under one hour per unit. 120 V version in development for North America; current unit 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### United States

Framework: Commercial kitchen exhaust is governed by NFPA 96 as adopted through state and local fire and building codes, plus IMC and IECC. A grease removal device not integral to a listed hood must carry a UL 1046 listing to be code-compliant, and insurers will decline coverage without it. Smoke and grease duct provisions and cleaning frequencies follow NFPA 96.

Relevance: Lynx Kitchen functions as a grease removal device in the airstream. UL 1046 listing is being pursued with our North American partner in the same test run as the Canadian CAN/ULC-S649 listing; until listing is in place the unit is specified as a supplementary separation stage. Continuous grease removal keeps the duct free of combustible deposits, reducing fire load and the cleaning frequency NFPA 96 requires, and makes downstream heat recovery practical under IECC energy provisions. The fail-open feature keeps the extraction path open in a fire event.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h (approximately 500 CFM), under one hour per unit. 120 V version in development for North America; current unit 220–240 V, 90 W, 180 Pa.

Datasheet: Coming soon.

### Singapore

Framework: Commercial kitchen ventilation is governed by three authorities — the Singapore Civil Defence Force (SCDF) for fire safety, the National Environment Agency (NEA) for odour and air discharge, and the Building and Construction Authority (BCA) for mechanical ventilation design. The applicable design code is SS 553 (Code of Practice for Air-Conditioning and Mechanical Ventilation). The SCDF Fire Code requires kitchen exhaust ducts to be fire-rated and maintained, with the entire interior and exterior of the duct and hood degreased at least every twelve months by a specialist, with records kept. SCDF identifies grease accumulation in kitchen exhaust as a leading cause of fires in food establishments.

Relevance: Lynx Kitchen is installed upstream of the fan and duct and does not change their fire rating. By separating 100% of the liquid fat droplets from the airstream continuously, it removes the grease accumulation SCDF identifies as the cause of duct fires and keeps the duct clean between the mandated annual degreasing intervals. The fail-open feature keeps the extraction path open in a fire. Chemical-free operation and clean discharge support the NEA air-discharge objective.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

### Hong Kong

Framework: Commercial kitchen ventilation is regulated by the Fire Services Department (FSD) with the building authorities. Mechanical ventilation falls under the Building (Ventilating Systems) Regulations (Cap. 123J) and, for licensed food premises, the Ventilation of Scheduled Premises Regulation (Cap. 132CE). Fire requirements follow the FSD Code of Practice for Minimum Fire Service Installations and Equipment, with fire dampers at fire-compartment penetrations and duct linings meeting BS 476 surface-spread-of-flame or an international equivalent. Under FSD Circular Letter No. 2/2023, metallic filter media coated with a combustible substance is reclassified as a special filter with additional fire-test and certification requirements.

Relevance: Lynx Kitchen is installed upstream of the fan and duct and does not change their fire rating or the Cap. 123J damper and lining provisions. By separating 100% of the liquid fat droplets continuously, the downstream duct stays free of the combustible grease layer a duct fire depends on, supporting the FSD objective and the Cap. 132CE maintenance obligations. The all-metal mesh variant carries no combustible coating, keeping it clear of the special-filter reclassification under Circular 2/2023. The fail-open feature keeps the extraction path open in a fire.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

Datasheet: Contact us.

### Malaysia

Framework: Commercial kitchen ventilation fire safety sits within the national fire framework administered by Bomba (the Fire and Rescue Department). The governing instruments are the Fire Services Act 1988 and the Uniform Building By-Laws 1984 (UBBL), supported by the Malaysian Standards. Compliance is demonstrated through Bomba approval of the building's fire-protection drawings, with early pre-consultation at the design stage recommended. Malaysian practice for kitchen exhaust draws closely on NFPA 96 principles: fire-rated grease ducts, fire dampers at compartment penetrations, and regular cleaning.

Relevance: Lynx Kitchen is installed upstream of the fan and duct and does not alter their fire rating or the UBBL damper provisions. By separating 100% of the liquid fat droplets continuously, it removes the grease accumulation that drives duct fires, keeps the grease duct clean between cleaning intervals, and reduces the fire load Bomba assesses. Because the cleaner duct and lower fire load can be documented, Lynx supports the design-stage Bomba consultation with a clear technical argument. The fail-open feature keeps the extraction path open in a fire.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. CE marked, 220–240 V, 90 W, 180 Pa.

## Use Cases

### Marine and cruise

A galley fire at sea is a different category of risk: there is no fire brigade, evacuation routes are confined, and a grease fire in the exhaust trunk can spread between decks and fire zones. The marine framework limits the consequences of such a fire but does not remove its cause. Lynx Kitchen removes the cause by separating 100% of the liquid fat droplets from the airstream continuously, before they reach the duct, so the combustible layer a galley fire depends on never forms.

SOLAS Chapter II-2, Regulation 9.7.5 governs galley exhaust ducts on passenger ships and cargo vessels (A-class insulation, fire dampers at both ends, remote fan shut-off, fixed fire-extinguishing system, inspection hatches). It requires a grease trap readily removable for cleaning unless an alternative approved grease removal system is fitted — and that exemption is the entry point: Lynx is positioned as the approved alternative grease removal system. DNV is the natural primary class route given the cruise and Norwegian-flagged vessel population and DNV's offshore separation heritage; Lloyd's Register and ABS apply parallel galley provisions, so a DNV type approval positions the product for cross-recognition. For marine use Lynx is supplied in the all-metal mesh variant (no polymer parts, no melt-out behaviour), holding full fire integrity and withstanding salt air and vibration across its 20-year component rating.

Installation: Retrofits on any galley hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit. All-metal stainless steel, 350 mm diameter, 17 kg, 220–240 V, 90 W, 180 Pa. Datasheet: coming soon (marine edition, DNV route in preparation).

### Airports

An airport food court concentrates more cooking output, longer hours and higher passenger density into one fire compartment than almost any other commercial setting, with long exhaust trunks running through occupied terminal space that are difficult to access for cleaning. There is no separate aviation standard: terminals follow the same national building and fire code as any building (in Norway TEK17 with Imkanal 2012:2 and NS-EN 16282), and what sets airports apart is the building owner's specification for documented continuous performance, building-management-system monitoring, and minimal duct access.

This is the profile Lynx Kitchen was proven against. The Lynx units at Oslo Airport Gardermoen comply fully with the Norwegian building regulations for the terminal, and Lynx Kitchen is the only documented solution that meets Avinor Oslo Airport's requirements for grease separation from kitchen ventilation. One installation runs a Lynx unit inside a Halton hood, and an ongoing SINTEF research project recovers heat directly downstream of a Lynx unit, returning it to the arrivals hall. The aviation reference configuration adds building-management-system interlock, continuous monitoring, and parallel-unit sizing for high-volume food courts.

Installation: Retrofits on any hood through a 360 mm opening, one unit per 850 m³/h, under one hour per unit, with no terminal duct modification. CE marked, monitored and interlocked to the building management system, 220–240 V, 90 W, 180 Pa. Datasheet: Norwegian/English datasheet; aviation reference edition in preparation and available on request.

## Lynx Embedded (OEM for hood manufacturers)

Lynx Embedded is the OEM configuration of Lynx Kitchen, designed to be integrated into a hood at the point of manufacture. The hood ships as one certified product with the separator already inside, so the customer buys a single unit that removes grease continuously from the day it is installed.

For the manufacturer it is a self-cleaning grease separator feature most hoods cannot offer: the hood separates 100% of the liquid fat droplets at source, keeps the downstream duct clean, removes the fuel a duct fire depends on, reduces the customer's mandated cleaning frequency, and makes downstream heat recovery practical — sold under the manufacturer's own brand, with no R&D spend and no change to on-site installation. It is low risk to adopt: CE marked, all components rated for 20 years of continuous operation, plug and play at 220–240 V, 90 W, and already proven inside a third-party hood at Oslo Airport Gardermoen.

The same platform is also available as a standalone retrofit unit and as a modular array for high-volume central extraction. Embedded module at a glance: 100% of liquid fat droplets down to 0.1 micron; 850 m³/h per unit (clustered in parallel for higher airflow); 180 Pa pressure drop (falling toward zero with the fail-open option in a fire); ø250 mm duct, ø360 mm mounting; 220–240 V, 50 Hz, single phase, 90 W; 7 kg composite or 17 kg stainless steel; CE marked, 20-year component rating; camera and building-management-system interlock. OEM enquiries: sondre@lynxkitchen.com.

## Fail-open (in development)

Fail-open is a safety feature: on a fire signal (heat trigger) the pressure drop across the unit falls from operating value (180 Pa) toward 0 Pa, keeping the extraction path to the fan open. This is particularly relevant for GC 11 installations in France (F400 requirement at 400 °C for 1–2 hours), but applies equally to all other markets where smoke evacuation capacity is critical in fire scenarios.
