Fumes are passed through scrubber systems which filter impurities out of the contaminated air stream. Industrial fans are used on either the dirty side of the air stream to push the toxic air into the scrubber or they can be used to pull and exhaust the clean air from the scrubber system. Chicago Blower offers both clean and dirty air scrubber fans that are constructed with special alloy materials and coatings for extreme protection while performing at the highest quality within scrubber applications.
