ATD Tools 7785 Coalescing/Oil-Removing Filter

Pipe Size: 1/2″ Bowl Type: metal; Operating Temperature: 40-160 F; Maximum Flow Pressure: 250 psig. 37 SCFM maximum; 9 oz. bowl capacity; overnight drain; .01 micron filter element. Removes submicron particles, particularly oil. Applications include paint spraying, pneumatic control instrumentation, printing and protection of air bearings. For maximum efficiency, a pre-filter needs to installed upstream of oil-removing filter. Coalescing filters function in a different way from general purpose filters. Air flows from inside to outside through a coalescing media. Coalescing by definition means ?to come together.? It is a continuous process by which small aerosols come in contact with the fibers in the filter media uniting with other collected aerosols and growing to emerge as a droplet on the downstream surface of the media which by its weight is gravitationally drained away. For maximum performance and efficiency, coalescing filters should be preceded by a general purpose filter.
