Powder Coating Booth

To understand the difference between powder coating and liquid coating paint booths it is best to understand how each type of booth works. A liquid paint booths always exhausts outside of the building while a powder coating booth in contrast will typically be able to discharge the air it pulls in back into your building. A powder coating booth relies on a cartridge or on a multi stage filter system to catch powder as it is sprayed and doesn’t adhere to a parts surface. A cartridge style powder coating booth enables the powder built up on the cartridge of the booth to be purged and with the right equipment in place recovered for easy reuse. A multi stage filtration powder coating booth captures powder that is wasted in filters and is generally known as a spray to waste powder booth because you cannot easily reuse the powder coating in this type of powder coating booth. Both powder booths rely on a fan pulling air through the booth, one into the multi stage filters and the other into the cartridges. They also will typically use a HEPA rated filter as this enables a powder booth to exhaust back into the shop because the HEPA filter collects all dust particles and allows the air that is discharged from the powder coating booth’s duct to be free of anything hazardous.
