Types of Industrial Filters Explained
Spin-on, cartridge, bag, panel and coalescing filters each suit a different job. A short guide to which is which.
Spin-on and cartridge filters
A spin-on filter is a sealed canister that screws onto a filter head and is replaced whole, which makes changes quick and clean on mobile equipment. A cartridge element sits inside a permanent housing, and only the element is replaced.
Coalescing filters
Particle filters trap solids. A coalescing filter instead merges fine liquid droplets, such as oil mist in compressed air or water in fuel, into larger drops that drain away.
Bag, panel and cartridge dust filters
Dust collectors use filter bags or pleated cartridges, and ventilation systems use panel filters. All of them offer a large media area to handle big volumes of dusty air.
