Grease removal apparatus, systems and methods

Abstract

A filter assembly includes a filter pad comprising fibers including natural, synthetic and / or hybrid fibers. A stabilizer frame formed of a non-metallic material may be imbedded in the filter pad. The stabilizer frame may be configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration. In accordance with a particular embodiment, the filter pad may be comprised of at least first and second fibrous mats that are coupled together. In this embodiment, the stabilizer frame may be disposed between and coupled with the first and second fibrous mats.

Description

technical field [0001] The technology of the present invention relates to the field of exhaust filtration in ventilation systems, in particular to grease removal equipment, systems and methods. Background technique [0002] In cook rooms, grease filters and / or grease removers are often installed in exhaust hoods above various cooking appliances that generate excessive heat and flames, including deep fryers, grills, frying pans and ovens . In applications using existing wool or fiber based filters (see eg US Patent 6,293,983), excess heat or flames can cause problems. Unless a stainless steel heat shield is placed in front of the wool filter, there is a possibility that concentrated heat (eg, exhaust from a cooking appliance) will degrade the wool fibers and cause holes to form in the filter. Similarly, if the flame is in direct contact with the filter (which can happen over grills and pans in the case of fat burning), the flame will create holes in the filter. This is a v...

Problems solved by technology

However, UL Standard 1046 does not adequately address the effectiveness of baffles in actually removing grease from the airflow and preventing it from entering the exhaust pipe

As a result, most baffles are poor at removing grease from the airflow
