A.C.T. Dust Collectors stock many standard sizes of blowers / fans, dampers, and silencers. These components are specifically designed for dust collection systems and are all heavy duty, industrial grade. Like our dust collectors, all of our blowers, dampers, and silencers are manufactured in the USA. We also offer top mount fans and ground mount fans. This is part of how A.C.T. Dust Collectors helps you to Maximize Your Air Filtration. To help you determine which fan is best for your dust collector, we recently published a blog entitled What Type of Fan Should I be Considering for my Dust Collection System?
