Turning the hand crank at 60 revolutions per minute (RPM) will give a blower output of 250 cubic feet per minute (CFM). When attached to a Safe Cell, the bank of filters imparts a resistance to the airflow that reduces it to a complete system output of 60 CFM.

Customers have been asking us for years to come out with a hand operated blower. The task proved more difficult than just finding some ready mad hand cranked blower and adapting to our Safe Cell filtration units.
