Contracor DBP DryBlast Compressed Air Aftercooler, Pneumatic

During blasting work, compressed air from a mobile or stationary compressor often contains a high level of heat and water vapour. If this air enters the blasting system without aftercooling, moisture can condense and cause the abrasive to clump. This can lead to inconsistent blasting performance, increased wear, longer downtime and additional maintenance. The DBP DryBlast is designed for installation between the compressor and the blasting equipment. The compressed air first passes through a heat exchanger, where it is cooled by a pneumatically driven fan. The cooled air then flows through a cyclone separator, where condensed moisture is removed from the air stream. The drier compressed air then continues to the blasting system. With the DBP, the fan is driven by an air motor. The fan speed is controlled by a pressure regulator on the air preparation unit. This unit also includes a filter and lubricator, so the moving parts of the pneumatic drive are lubricated and additional condensate is separated. Key benefits Pneumatically driven No electrical connection required for the fan drive Helps remove condensate and oil from the compressed air stream Reduces abrasive clumping Helps reduce the risk of blockages in metering valves, hoses and blast nozzles Cools compressed air to approximately 3 °C to 10 °C above ambient temperature Equipped with an efficient cyclone separator With air preparation unit, pressure regulator, filter and lubricator Mobile design with transport wheels and handle Suitable for use between compressor and blasting system Technical data Model Capacity Connection Air motor pressure Air motor consumption DBP-3 3 m³/min G1" 2–6 bar 0.6–1.4 m³/min DBP-7 7 m³/min G1½" 2–6 bar 0.6–1.4 m³/min DBP-12 12 m³/min G2" 2–6 bar 0.6–1.4 m³/min DBP-16 16 m³/min G2" 2–6 bar 0.6–1.4 m³/min DBP-21 21 m³/min G2" 2–6 bar 0.6–1.4 m³/min DBP-25 25 m³/min G2" 2–6 bar 0.6–1.4 m³/min
