FM Approved Dry Air Pac
for Critical Applications where
Moisture Removal is Essential

General’s DAP Series Dry Air Pac TM is an FM Approved, twin tower regenerative dryer / compressor package. This turnkey system is designed to provide the sprinkler system with moisture free air to a -40 deg. F Dew Point. The air compressor is designed to fill the sprinkler system in accordance with NFPA 13 standards, as well as provide the higher pressure needed to allow the twin tower regenerative dryer to function properly.

Prior to entering the regenerative air dryer, an air cooled aftercooler cools the compressor’s hot discharge air to a maximum 100oF. A coalescing prefilter with differential pressure gauge removes oil vapor and other contaminants that can destroy the desiccant in the dryer towers. A combination particulate filter and regulator prevents downstream migration of desiccant dust while regulating air pressure to the sprinkler system.

The FM Approval on the Dry Air Pac TM eliminates the requirement to connect the air intake to the freezer room. NFPA 13 exempts any approved packages from this costly requirement. General’s Dry Air Pac is the only package on the market that meets this exemption.
