Collection: Trident Compressed Air Dryers and Filtration

Trident builds the three pieces of a compressed air treatment package: refrigerated dryers, desiccant dryers and coalescing filtration. We carry the line because it lands between the economy imports and the big factory brands on price without giving up the pressure dew point you actually need.

Refrigerated dryers

A Trident refrigerated dryer chills compressed air to condense water out and holds a pressure dew point near 38 degrees F. That is enough wherever the piping stays above 38 degrees, which covers most indoor plants. Ratings are published at 100 degrees F inlet, 100 degrees F ambient and 100 PSIG. Feed one hotter air or run at lower pressure and real capacity falls 20 to 40 percent, so correct for your conditions before you pick a size.

Desiccant dryers

When the air feeds paint, powder coating, instrumentation, food processing or electronics, or the pipe runs outdoors where it freezes, you need desiccant and a minus 40 degree F dew point. The trade is purge air. A heatless desiccant dryer regenerates on 15 to 20 percent of its rated flow, so a 200 SCFM unit takes 30 to 40 SCFM back off the compressor. Budget that before you size the compressor, not after.

Filters

Drying alone does not get you clean air. Trident compressed air filters pull out particulate, oil aerosol and carryover. Standard practice is a coalescing filter ahead of the dryer and a particulate filter behind it, with elements changed on measured pressure drop rather than on the calendar. A plugged element quietly costs 5 to 10 PSI that you are paying the compressor to make.
