In order for the kitchen extract system to function correctly, it is essential that an allowance is made for the provision of replacement or make-up air. This is achieved either by introducing mechanical supply air, or by making provision for natural infiltration (DW/172). This is particularly important when gas burning appliances are used in the kitchen. In this instance it is required to comply with gas regulations.
All our systems include a filter system to ensure incoming air is not contaminated with airborne debris. If required the incoming air can also be heated.
Make-up air can be introduced into the kitchen as follows.
- Through a perforated face or diffuser grilles mounted in the canopy face
- A separate plenum located elsewhere in the kitchen
- Ceiling grilles
- A combination of the above
