PARTS OF THE SYSTEM

PARTS OF THE SYSTEM

HOOD / CANOPY

It is imperative that the hood above cooking appliances (stoves, ovens, fryers, grilles etc.) be kept in pristine condition on both hygiene and fire safety grounds. This area includes the oil drains and light fittings. And let’s face it, a dirty hood covered in grease, oil, fat, soot, dust etc. is a slur on the good reputation of the chef and the restaurant.

FLUES

A buildup of oil, fat, grease, soot, dust and debris is a health and fire risk as it reduces air flow. These materials may then drop back down through the hood and filters onto the appliances and food below. Clean ducting ensures maximum efficiency from your extractor system.

ROOFS

Fan units often blow fat, oil etc. out on to the roof which must be cleaned off to avoid it running into storm water drains. It also taints paintwork and galvanising, causing corrosion of metal roofs. It can also look unsightly from the road or front of your restaurant.
