The Bag-in Bag-out Pulsejet Collector BBP is a pulse jet type bag filter designed for hazardous materials. The filters can be exchanged simply by pushing the new filter into the filter inlet port located on the clean casing side of the bag filter. The used filter will be pushed out from the bag filter through the dirty side outlet port. (This mechanism is called the“Push-Push method”) The used filter will be directly discharged into a preattached plastic disposal bag. The inlet and outlet ports will be enclosed with plastic bags during filter exchange, preventing any powders from scattering at a high level. The procedure of inserting the filter from the clean casing side minimizes the risk of powder scattering even in rare cases of breakages to the plastic bag.
