DFB -Tube-Axial Belt Drive Duct Fans

  • Heavy 14 gauge steel drum including mounting flanges, each end. 
  • Industrial charcoal grey enamel finish. 
  • Most models available with open drip-proof, totally enclosed dust proof or explosion proof motors in 1 or 3 phase. 
  • Completely enclosed belt and ball bearing housing - ball bearings are sealed with external grease fitting. 
  • Adjustable motor base for proper alignment. 
  • Rugged heavy-duty cast aluminum propeller. 
  • Fan can be mounted for either vertical or horizontal exhaust. 
  • Eliminates fumes and vapors from paint spray booths and other hazardous areas - a non-explosion proof motor can be used when motor is located in an area away from hazardous vapors. 
  • Maximum temperature 180ºF dry air. For applications where temperature is greater than 180ºF. For wet applications, consult factory. 
  • Optional access doors allow for periodic cleaning and inspection. 
  • Recommended for most paint spray applications because motor is out of air stream and not exposed to paint over spray - less motor maintenance. 
  • Exhausts underground vaults and conduits - used for heating and air conditioning transfer in shopping malls, institutions and commercial buildings - removes excess heat and gases from work stations. 
  • Matching flanges and belt guards are available options. 
  • Corrosion and chemical resistant protective coatings available - consult factory for price and delivery schedule. 
  • Each 45 or 90 duct bend increases static pressure - consult factory for CFM recommendations.
