DATA SHEET – CEM Axial Blowers – VE and VEX



CEM electric VE and VEX Axial Fans (helical or helix) are widely used on board for suction and ventilation of air in a closed environment such as; toilets, bathrooms, kitchens, galleys, and engine rooms

Axial fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans

Axial fans are named for the direction of the airflow they create. Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction

Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflows they create are of low pressure. They require a low power input for operation


Direct current: 

  • Permanent magnet motor 12/24 VDC
  • Protection IP44 (IP55 available on request)
  • Insulation Class F
  • Continuous Duty (S1)

Alternating current:

  • Induction electric motor
    • 110/230V single-phase (M) – 50Hz (60hz available on request)
    • 230~400VAC (T) – 50Hz (60hz available on request)
    • 400~690VAC three-phase (T) – 50Hz (60hz available on request)
