Filter System With Integral On Board Compressed Air Generator

摘要

An air filter system for use in industrial applications, particularly, in welding operations. The system has a fan for drawing air into a housing and an air outlet for exhausting air from the housing. At least one filter is mounted within the housing between the air inlet and the air outlet. Air is passed through the filter as it is drawn into the inlet and exhausted from the outlet to retain particulates entrained in the air. At least one air injector is mounted adjacent the filter to clean the filter by forcing air into the filter to remove the retained particulate from the filter. An onboard compressed air generator is mounted within the housing to supply compressed air to the air injector for injection into the filter.
