How we do it
Where gas appliances are used, the gas supply is normally interlocked with the ventilation so cooking cannot run without extract, as BS 6173 sets out. Planning conditions often require odour control and limits on noise at the discharge. We fit out new restaurants, cafés, takeaways and staff canteens, and replace or extend extract when menus or equipment change.
Make-up air
Tempered fresh air to replace what is extracted.
Odour control and interlocks
Carbon filters or other odour control to meet planning, and gas interlock systems.
Wall and island canopies
Stainless steel canopies with baffle grease filters and lighting.
