JEC – DC Marine Brushless fans

  • Diameter – Measurement across blades
  • Pitch – The higher the pitch the higher the air flow
  • Reversible – Reversible blades have lower capacity
  • Motor:
    • MF1: 0.75kW
    • MF3: 4kW

Note: Single direction blades as standard. All motors are reversible but when in reverse there is lower performance on standard models unless reversible blades are used



DC Marine Brushless fans, a spark-free operation for engine rooms and compartments that require reliable low maintenance ventilation with high water ingress protection 

The advantages of a brushless motor over brushed motors are high power to weight ratio, high speed, and electronic control

Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles and now marine ventilation

JEC’s Marine Engine Room Ventilation Fans The JEC range of DC marine fans are extremely powerful for their size and available with a range of blade pitches that can be tailored to meet your engine room needs

Key Features

  • Brushless design for maintenance-free operation
  • An ideal combination of high volume flow with a lightweight, compact construction
  • Variable speed and pitch to suit your requirements
  • Very high efficiency for power and fuel savings
  • Operates directly from your engines DC supply
  • Built to naval standards throughout for long life under the most arduous conditions

Fan Motor and Construction

For the first time, a brushless design gives maintenance-free operation with outstanding reliability. The precision built DC motor is half the size of a similar AC powered motor, saving weight and improving fan blade efficiency

For exceptional corrosion resistance, components are stainless steel or hard anodised aluminium, sealed with sodium dichromate, the type of treatment used on navy ships and large aircraft
