Filter dust collector

Choice of the correct model of dust collector is essential for any closed blasting system. The removal of airborne particles from the environment of a blast chamber is essential to maintain efficient operation. Savings made by cutting cost at this point will only lead to reduced efficiency, early failure of the system and higher running costs. Factors to consider whilst choosing a dust collector are: Correct air speed through the blast room prevents settlement of airborne particles in the work area. The direction in which the air flows through the blast room is critical to the process. Correctly sized and positioned air inlets and extraction duct work ensure that first class ventilation is achieved. The filtration area is the surface area of the filter material within the dust collector. It is essential that the ratio between filtration area and air volume is correct to prevent premature failure of the extraction system. Reverse pulse dust collectors use filter cartridges which are cleaned whilst the collector is in operation ensuring the efficiency of the collector is maintained. A short pulse of air causes the dust accumulated on the cartridges to fall into collection bins below at pre-determined intervals keeping the cartridges clean whilst the collector is in operation. Reverse pulse dust collectors can be used with high specification filters on hazardous dust applications and can be operated in conjunction with secondary or HEPA filters for increased efficiency.
