GIF convex restaurant system

High airflow rates within a small area

It can be easily upgraded due to the modular character


This high performance separator fits neatly into the ceiling grid and is used mainly above deep frying and frying sections. It enables concentrated air extraction at the point of origin.

When using high performance separators, up to 2400 m3/h m2 can be extracted.

The high performance separators are inserted at a sloping angle into the GIF Restaurant System, so that the aerosolate amounts (intercepted aerosols), which are very high in these areas, are drained into the integrated collecting trough. This trough can be emptied at regular intervals via an integrated drain trap.

The GIF separator is available in convex or concave forms. The classic version in concave form protrudes from the ceiling as a trapezium.

Like all air handling components, the GIF Restaurant System is also, as standard, made of AISI 304 stainless steel. The high performance separators can be easily removed from the ceiling and cleaned in the dishwasher. The collection trough is, as a result, also easily accessible and readily cleaned.

High airflows possible thanks to the storage volume


This high performance separator fits neatly into the ceiling grid and is used mainly above deep frying and frying sections. It enables concentrated air extraction at the point of origin. When using high performance separators, up to 2400 m³/h m² can be extracted.

The high performance separators are inserted at a sloping angle into the GIF Restaurant System, so that the aerosolate amounts (intercepted aerosols), which are very high in these areas, are drained into the integrated collecting trough. This trough can be emptied at regular intervals via an integrated drain trap.

The extracting surface lies inside the ventilated ceiling, thanks to the system mounted flush with the ceiling a uniform view from below is achieved. In this way a restricted view, which occurs especially with low ventilated ceilings, is avoided.

Like all air handling components, the GIF Restaurant System is also, as standard, made of AISI 304 stainless steel. The high performance separators can be easily removed from the ceiling and cleaned in the dishwasher. The collection trough is, as a result, also easily accessible and readily cleaned.

The entire GIF Active Cassette Ceiling is designed as an area-active, modular cassette construction and performs both extract air function above cooking appliances as well as air supply function outside the extract air areas. The active cassettes serve as aerosol separators on the extract air side according to VDI 2052 and DIN 18869-5 and form a large-scale extract air area. Moreover, flame propagation safety has been certified by ULC (Underwriters’ Laboratories of Canada).

The active cassettes are manufactured only from AISI 304 stainless steel and achieve the highest degree of separation (up to 97%) as a result of very tight manufacturing tolerances. The exhaust flow velocity above the active cassette is so low (0.08 m/s) that floating particles, which have not been intercepted in the separation chamber, drop back onto the top of the cassette surface by mass inertia.

All active cassettes can be removed from the ceiling grid simply by pushing and pulling them in the rows. Therefore, the GIF Active Cassette Ceiling can be removed from virtually any location almost entirely (≈ 98%) and can be cleaned in any industrial dishwasher. This means that climbing on kitchen equipment is not necessary and hygienic cleaning is guaranteed. The unique modular system offers very high transparency and hygiene due to a construction which is fully reversible. On the air supply side, the GIF Active Cassette Ceiling is used for supplying low-turbulence fresh air on a large scale according to the principle of layered flow, thereby ensuring an energy-efficient solution as standard. The special design ensures an indirect fresh air flow, even with high air volumes and low inflow speeds, without induction impulse.

Since the active cassettes for the extract air and the fresh air areas are identical, they are fully interchangeable in any configuration.



Facts and Advantages

  • Compliant with or exceeding current directives and standards (VDI 2052, VDI 6022, DIN 18869) also including the inspection capability of components from above (no access panels needed)
  • Durability of the AISI 304 stainless steel material
  • Interlinking cassettes facilitate quick and easy removal
  • Economic and hygienic cleaning of only 4 components per m2 in the dishwasher
  • Active cassettes can be pushed and pulled in the suspension profiles, as a result they are easy to remove without the need for tools
  • Partial cleaning is possible if required
  • No need to climb on greasy, hot kitchen appliances (danger of slipping)
  • HACCP certified
