Abstract:
The present invention is directed to a gas particulate treatment system and may include a gas filter and a gas filter performance monitor downstream of the gas filter. The gas filter performance monitor includes a particulate trap operable to collect particulates passing through the gas filter, and a sensing apparatus associated with the gas filter performance monitor that operates to sense particulate collection in the gas filter performance monitor.
