Moisture Block

Moisture Block Desiccant Air Dryers

Van Air Systems Moisture Block is the simplest, most cost effective point-of-use compressed air dryer available anywhere. Until now compressed air users in the light industrial market, those using 10 horsepower reciprocating air compressors or smaller, needed to choose between inexpensive dryers with high operating costs or expensive dryers with low operating costs. The Moisture Block is a unique dryer that merges low initial cost and low operating costs.

The Moisture Block delivers moisture free air. With the use of activated alumina desiccant it is capable of achieving a -40ºF pressure dew point. The Moisture Block allows you to spray paint, sandblast, run tools or plasma cutters for months and even years before needing new desiccant. 

The Moisture Boss is what a point-of-use dryer should be. Simple, affordable and effective.
