Why do exhaust filters last longer?
Exhaust Filters: Your exhaust filter takes the hardest hit because it is responsible for keeping paint overspray from building up on your fans. The stronger the exhaust fan, the heavier the contamination over time.
How does a paint booth filter work?
How Filters Work. In its simplest terms, a filter is a screen that blocks certain debris and contaminants in the air from being released into the air. However working inside of your paint booth are different filters working at cross-purposes. At the front end of your filter system is your intake unit filter.

What is GFS wave?
GFS Wave is a nonwoven polyester media comprised of coarse and fine, standard and low-melt fibers chosen for performance in overspray collection applications. This means that the fiber blend, along with the wave pattern, enables paint-laden air to be captured across the surface and within the depth of the media, extending filter service life and reducing operating costs.

What is Water Wash Filtration?
Water wash spray paint booths use water as a filtration medium instead of dry filters . Paint overspray is collected and trapped in the water curtain or scrubber section of the washer and then is dropped down into a collection tank. The collection tank eventually becomes filled with paint sludge and then needs to be cleaned. A centrifuge or sludge removal system can help reduce downtime for cleanings: they can be designed into the booth system to remove the paint sludge on a continuous basis. Water wash filtration systems require a high initial investment but are ideal for operations using very high paint volumes that need a uniform and consistent airflow.

Why does water sludge sink to the bottom?
Manufacturers must be aware of stringent regulations on the draining and treatment processes for water with sludge. The water, which is chemically treated to bond with spray particles, separates the compounds through an ionization process that causes them to float on the surface or sink to the bottom as sludge. Without a centrifuge system, floating compounds must be periodically skimmed from the surface to ensure consistent and smooth operations of the washer, and to remove the sludge to hazardous waste. The particles that sink to the bottom of the tank are shoveled out and disposed of as hazardous waste.
