UPGRADABLE BLOWER

The BELFAB open dust collector modular series comes with our patented upgradable blower, that makes it possible to increase blower performance (on our standard blower) from a 5HP/2500CFM to a 20HP/ 6000 CFM MAX by simply replacing motor and impeller within the same fan housing.

Our optional HUMMER 1800 RPM fan offers super quiet operation at up to 9000 CFM* (see note). In applications where there is a requirement for low sound level (under 84 db), BELFAB HUMMER series is available for application ranging from 10HP to 20HP 5000 CFM.

*up to 5000CFM for indoor installation. Above 5,000 CFM an outdoor set up is required  (NFPA 664)

FEATURES

  • Vertical mechanical manual shaker cleaning system
  • Low maintenance direct drive centrifugal fan
  • High efficiency TEFC motor, CSA-UL or CSA-US approved
