The ABT model Centrifugal Blowers acheive higher pressures and airflows than our ABC models of centrifugal blowers. Our Centrifugal Blowers run at relatively low sound levels assisting in reducing industrial noise ensuring a quieter work environment. Our impellers and housings are constructed from anti-sparking, highly resistant, cast aluminum in order for our centrifugal blowers to endure the harshest environments. Our Centrifugal Blowers meet CE, UL, ATEX, CSA, ISO9001, and CSA certifications.
