Category: Kitchen Exhaust Systems
A commercial exhaust hood, or even a number of hoods, depending on the size of the kitchen, is crucial to any commercial kitchen venture. These are needed for any commercial cooking where grease is involved, to extract the heat and grease-laden vapors generated, so the kitchen runs safely. It is important to get the right equipment for your situation. With a properly designed commercial hood system, you can keep your business legal as well as run it efficiently. It’s not possible to use a hood made for a domestic kitchen in a restaurant or commercial food preparation area, because of the level of heat, grease and vapor produced in commercial kitchens, of whatever size.
A commercial hood vent needs to remove steam, smoke, grease and heat from the food preparation area. This is why commercial vent hoods are installed directly over the heating areas in your restaurant. Then they can collect heat and grease at source. There are baffle filters inside the vent hood to filter out as much grease as possible so it doesn’t enter the ducts forming your ventilation system. The type of baffles you will need are determined by the cooking system in your kitchen, however, even with the best baffle filters, some grease will get through and the system will need regular cleaning. Because of this residual grease, it is vital to be able to clean the ventilation fan and the ductwork from the top, and this means you will need a hinged cover on the exhaust fan in the vent hood. This will reduce the risk of fire hazards and keep your kitchen safe.
Along with the heat and the grease-laden vapors, the exhaust fan also removes air from your commercial kitchen and that needs to be replaced. This is done with a “make-up air unit”. This brings in clean, fresh and usually cooler air to the kitchen and makes up for the hot greasy air removed by the fan. In total, the extraction canopy for the removal and the make-up air unit for replacement of hot air by clean fresh air, form part of any industrial kitchen hood system.

Extraction Hoods and Canopies are vital parts of any commercial kitchen and should be fabricated from Stainless Steel for best safety. They are also legal requirements, to control the environment and guarantee everyone’s health and safety.
Commercial kitchens generate large amounts of heat from their burners, especially when working at full capacity and the ventilation system has to be able to cope with this. Canopy hoods are designed to work efficiently in different positions in the commercial kitchen. Wall hoods are used where cooking equipment is set against a wall. Where equipment is situated in an island set up, then single island hoods are used. All appliances generating fumes in a commercial kitchen should each have a canopy. Canopies deal with a lot of heat; and stainless steel is an excellent material when used as part of an overall system for managing this heat safely. An effective canopy should also discourage condensation because that will lead to the accumulation of particles inside the hood. The duct needs to be well insulated to allow the system to discharge hot air at the outlet, not within the building.
The extracted air needs to be replaced with fresh air to restore what is removed and to maintain atmospheric pressure. Replacement air systems can obtain air both from outside, for instance, a rooftop unit, or internally, perhaps from the dining area. The air is filtered and then heated or cooled to the correct standard.
Filters in the canopy hood remove grease residues and particulates from the air inlets. However, grease can still get through and build up in the ducts, if the system is not cleaned regularly. This can cause a fire hazard. Access is important for commercial kitchen ventilation systems. They need regular cleaning to maintain safety; and good access is vital for this work to be carried out. It’s also needed for maintenance, inspection and component replacement.
