Through this article you can understand the basic components and the functioning of a kitchen exhaust system and will be aware what goes into the replacement process:
Duct system: As the name implies, they have a ductwork for air distribution. They incorporate the placement of a duct and pipe system that takes up the space of a wall or a cabinet. These ducts are made out of stainless steel or any non combustible material for durability and should be resistant to rust and corrosion.
Make sure the distance between the duct from and the stove is between 26 to 30 inches.
The kitchen duct system is made up of the following components:
Hood: It is the section just above the cooktop that transports all of the hot air, and this air is absorbed by a propeller on the inside of the hood.
Fan/Blower:The heated air as well as other contaminants are absorbed by the fan installed within the hood.
Honeycomb filter: removes all of the drippings and other cooking residues from the exhaust fumes. Make sure the filters are installed in such a way that you can remove them yourself for cleaning.
Ozone generator: helps clean contaminated air by oxidising with effluents and releasing oxygen, a process known as oxygenation.
