Modern dust collection systems utilize a number of methods for cleaning filters. The most effective of these is the pneumatic pulse-jet process, which sends a countercurrent pulse of air into the output of the filter media (typically a sleeve or cartridge design) to temporarily reverse the direction of airflow. This quick burst of air ejects the swarf from the filter media while the dust collection system is still in operation. The pulse-jet filter cleaning process is also the least damaging to filtration media, maximizing filter life and reducing the total cost of ownership of your dust collection system.
COIMA products which utilize pulse-jet cleaning include an electric consumption optimizer which adjusts the frequency of the pulse cleaning operations based on measured filter performance. This not only optimizes the filtration capacity of the dust collection system but also saves energy by consuming less compressed air.
