The purpose of a kitchen duct extraction system is to remove greasy air from a commercial kitchen. This is an essential device to ensure that the indoor air quality within the kitchen is healthy for the employees that work there. During the cooking process, grease from fats and oils along with any possible fuels (charcoal and wood) are removed from the kitchen through the extract system. Along the way through the extraction system, the hot air begins to cool and attaches itself to the duct, forming a jelly like substance on the side of the duct. This jellied grease has now become the biggest safety and fire risk in your kitchen; hotel and building.
