S253 Fire Protection Air Compressor for Reliable’s DDX-LP Valve

C-Aire’s S253 riser mount fire protection air compressor is the perfect match for Reliable Automatic Sprinkler’s DDX Low-Pressure Dry Pipe Valve. Low-pressure dry systems featuring the Reliable DDX-LP can improve water transit times following the operation of the valve, and in some cases, eliminate the need for a quick-opening device. The pressure switch comes preset for the DDX-LP at 23-28 psi. Our S253R is ETL Listed to comply with NFPA 13 requirements and utilizes the same convenient mounting bracket as our other riser mount compressors.
