Acme Superwindmaster Fans

Acme Fans – SuperWindmaster

DC SERIES (STEEL)

Acme Super Windmaster belt driven fan

  • Six-bladed propeller utilizing a cambered – twist blade designed with a unique dihedral tip for higher air flow capacities at less horsepower.
  • Non-overloading design maintains horsepower within catalog range of static pressure, resulting in lower motor load and reduced operating costs.
  • Streamlined orifice insures higher air flow capacity.
  • Available mounted in either slant or square wall housing.

ACMA sealAcme Engineering and Manufacturing Corporation certifies that the Super Windmaster DC shown herein is licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and AMCA Publication 311 and comply with the requirements of the AMCA Certified Ratings Program.

SEALED BEARINGS

  • Sealed, pre-lubricated bearingsPre-lubricated oversize ball bearings are double sealed, require no service.
  • Improved, more efficient drive assembly and super-duty neoprene belts provide longer service life.

ENERGY EFFICIENT ENCLOSED MOTORS

  • Heavy duty totally enclosed motors with shielded ball bearings are designed for continuous work load.
  • Available in two speed.
  • Built-in thermal overload for low-line voltage protection on all single phase motors.

MOTOR NOTES

  1. All single speed single phase motors are dual voltage (115/230) except 1/4 horsepower.
  2. All 1/4 horsepower single phase motors are single voltage (115 or 230).
  3. Two-speed motors are single voltage (115 or 230) and not available in 11/2 horsepower.
  4. Low speed capacity of two speed fans is approximately one half of maximum.
  5. All three phase motors are triple voltage (200-230/460).
