Backflush Filter Cleaning System and Method of Use

摘要

A backflush filter cleaning system for use with a vacuum cleaner employing an internal filter may include a filter cage having a first end, a second end and a peripheral opening, a backflush valve coupled to the first end, an intake plenum coupled to the second end, the plenum having an air outlet, an inlet valve coupled between the peripheral opening and the air outlet, and a cleaning actuator coupled to at least one of the valves. The system can be adapted to clean a filter coupled to a vacuum cleaner where the system can include a means for establishing a first airflow path from inside the collector through the filter, to the vacuum source, a means for flowing air along the first airflow path, and a means for establishing a second airflow path from an atmosphere surrounding the vacuum cleaner through the backflush valve, through the filter, and into the collector to clean the filter.
