Many people believe the solution to obtain clean, dry, oil free air is to place a drying device at the shop compressor.  This is not a total solution to the contamination problem.  Refrigeration units and twin tower dessicant systems used in this solution can cost upwards of $5,000.00 and they do not deliver complete results.  One large device will usually service a number of tool locations.  Air travelling downstream from these devices can pick-up moisture from condensation, pipe scale, rust and other system contamination ending up in the tool.

The inexpensive, ultra high efficiency ShopAir Air Filter/Coalescer is a small, lightweight unit that can be conveniently and effectively located near the air using device, removing contaminates at the end of the line.
