General purpose compressed air lters remove water and particulate material from the air stream to protect downstream equipment from contamination. As air enters the lter, internal bafes create a swirling motion to the air so that entrained dirt and liquids are thrown against the sides of the lter bowl and then fall to the sump area at the bottom of the bowl. Additional bafing keeps the air in the sump area relatively quiet; this ensures that the removed material is not returned to the air ow going to the lter element. The lter element will then collect smaller particles. The most frequently used element in Master Pneumatic general purpose lters is rated at 5 m, so that nearly all particles larger than 5 m (half the diameter of a human hair) will be collected in the lter element.

Modular assembly and mounting. Threaded ports or quick-connect fittings for tubing up to 10 mm in diameter. 0.3-m-rated coalescing filter element; optional 0.01-m-rated element. High-strength polycarbonate plastic filter bowl; optional aluminum bowl. Internal automatic drain; optional manual drain. NPTF port threads; optional BSPP threads. Application Note: A general purpose filter must be installed ahead of a coalescing filter to ensure good performance and to extend the life of the coalescing element.

The adsorbing filter is designed to remove vapors from the air line that cannot be removed by a coalescing filter. It produces air free of oil and hydrocarbons as required by industries such as food processing, electronics, and instrumentation. An adsorbing filter preceded by a coalescing filter and a general purpose filter constitute a Clean Air Package.
