Brushless DC Fan

The Gofee Brushless DC Fan is designed to provide movement of air in exhaust systems. Suitable applications include exhaust in farming/factory/greenhouse/animal husbandry in multi-story, multi-family buildings.

The fan casing is made of molded fiberglass reinforced plastic (also available in hand-glued FRP), and the fastening screws are detachable for easy maintenance. The fan ensures the negative pressure throughout the workspace. The fan is mounted on the side or top of the building and can be installed on sideways or vertically. If side wall ventilation is used, the exhaust direction is horizontal. Gofee fan is suitable for environments where the exhaust temperature does not exceed 60 ℃. In order to achieve a better exhaust cooling effect, it can be combined with cooling pads.

  • UV resistant mould shaping glass fiber reinforced fan housing material, corrosion resistant, maintain color and shape.
  • Die cast aluminum rugged blade according to airflow dynamics design, ensure steady working. Stall limit configuration prevents motor overload and airflow increase, improve efficiency and save energy.
  • Air downstream made PVC shutter, stop insect and air counter flow. Shutter open by air, minimum wind resistant.
  • Inlet and outlet conforms to airflow dynamics science, maximum high air performance.
  • Fan with brushless DC motor ,with great energy efficiency ratio 30% higher than normal one.
  • 0-10V, stepless speed regulation ,control and keep fan speed running stable.
  • Motor is fully enclosed structure, with very high protection level, reliable and long service life.
  • Fan direct drove  by motor , without belt pulley drive, more convenient on maintenance.
  • 18” fan housing to be manually formed. (optional)
