Kitchen exhaust systems provide a means to remove heat and contaminants (smoke, grease and aerosols) generated during cooking operations. While exhausting these items provides a better indoor environment, it can cause problems outdoors to neighboring facilities due to the associated odors and particulates emitted. The amount and type of contaminants generated from a kitchen exhaust application will depend on the cooking operations taking place inside. The contaminants include gases, vapors, aerosols, and particulates. Therefore, kitchen exhaust filtration must incorporate a wide range of filtration types and be versatile to provide an adequate solution.
Commercial kitchens typically include grease and moisture capture devices at the cooking locations. These may be in the form of hoods with baffle or other type of filters to remove the initial amount of grease particles.
