    The C-Aire S253 riser mount fire sprinkler air compressor is the perfect fit for Reliable’s DDX-LP 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 S253R is ETL Listed to comply with NFPA requirements and utilizes the same convenient mounting bracket as our other riser mount compressors. The pressure switch comes preset at 23-28 psi. Whisper quiet, compact units that are specifically designed for settings where noise is a concern. These units are oil-free, easy to install, and low maintenance. New construction or tight systems with minimal air leaks are a good match for this series. Our fire protection air compressors are specifically engineered for dry pipe & pre-action fire sprinkler systems. We are committed to enhancing the fire protection industry using customer feedback, new technology, and industry trends to deliver innovative solutions to the market.
