Kitchen extraction for Longfield premises
Canopies need to overhang the cooking equipment, use grease filters suited to the cooking, and have access for cleaning. 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.
Extract fans and ductwork
Fans sized to the canopy, with access panels for cleaning.
Make-up air
Tempered fresh air to replace what is extracted.
