Applications	N/A These direct drive tube axial fans are recommended for duct application in mills, mines, foundries, factories or wherever fumes, dust, smoke, or steam must be removed. Propellers are non-sparking cast aluminum so that unit with explosion proof motor can be used to handle explosive gases. Drum made from heavy gauge steel. Welded construction. Angle iron flanges on each end of drum with eight mounting holes for ease in mounting into duct. Motors - only high quality industrial motors are used. Fans with motors are completely assembled and fan tested at factory before shipping. Motors are available in open drip proof, totally enclosed and explosion proof. Model DF fans may be specified for any application where it is permissible to allow the motor to run in the air stream.
Accessories and Options	N/A Companion Flanges - For easy installation. Protective Coating - Epoxy or Eisenheiss coatings provide good protection against most corrosive agents. Access Doors - Gasketed and latched hinged access doors allow for periodic inspection of motor and propeller.
