CONTROLLED PULSE AIR FILTER SYSTEM

摘要

An air filtering system and method for self-cleaning the same is provided. The system has a plurality of air filters including a first filter and at least one neighboring filter. A blower fan pulls air through the filters. A plurality of compressed air injectors are provided adjacent the filters including a first injector and at least one neighboring injector. Self-cleaning is achieved while the blower fan is running by preforming several steps including activating the first injector to force compressed air into the first filter and discharge particulate from the first filter followed by deactivating the first injector. The steps further provide reactivating the first injector and simultaneously activating the neighboring injector while the discharged particulate is airborne to provide an air shield about the first filter and force the discharged particulate away from the first filter and the neighboring filter. These steps are repeated for each filter.
