Kitchen Exhaust Duct Cleaning

Grease-laden kitchen ducts presents one of the most serious and common fire hazards in a building. One in every fourth accidental fire in a commercial building is attributed to cooking and extraction systems. In the U.S. alone, cooking caused 27,400 fires in non-residential buildings in 2013 (51% of all fires)1.

Kitchen extract systems are coated with grease, oil, and other residues that may ignite and cause fire to spread rapidly throughout the exhaust system. In a worst-case scenario, this may cause deaths and substantial property damages vulnerable to prosecution. Poorly maintained kitchen extraction ductwork is an obvious fire risk and thus can render insurance policies invalid. Therefore, it is vital to keep kitchen ducts clean.

Unfortunately, many entrepreneurs and companies are still offering vague services promising to clean kitchen exhaust ducts. However, these companies usually just wipe the area that can be reached by hand, while major parts causing the fire risk is left unclean. Lifa Air has more than 25 years’ experience in providing state-of-the-art kitchen exhaust cleaning systems.
