ATD 7862 1/2" Two-In-One Filter, .03 Micron, Coalescing, 55 SCFM 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 and then gravitationally drained away. For maximum performance and efficiency, coalescing filters should be preceded by a general-purpose filter. Features: Removes sub micron particles, particularly oil Applications include paint spraying, pneumatic control instrumentation, printing and protection of air bearings For maximum efficiency, a pre-filter needs to be installed upstream of the oil-removing filter Specifications: Pipe Size: 1/2" Max.
