Abstract

Proposed is a method that accurately determines correct operation of air moving devices (i.e-, fans and blowers). A vane mechanically coupled to a switch senses air flow. The vane assembly is located between the output of a blower/fdter stage and the input of an ozone frlter stage. Independent testing of each fan stage allows the determination of the total system operation. The proposed method provides a means for remotely diagnosing an air filtration problem.
