Keep your engine room cool

Our DC high volume fans are an alternative to our High Volume AC Fans if you are running a DC system. They are perfect for controlling the induction of air into and around your engine room.


Our DC High Volume Fans are 24 volt only and come in 3 different footprint sizes, 340x390mm, 440x490mm & 540x590mm. The fans can move between 750 litres per second up to 3410 litres per second based on the size and Amps.


These DC Axial fans are supplied in an Aluminium 5083 grade housing and have synthetic impellors and a DC brushless motor.


We can also supply Air Diverters to control the direction of air produced by the fans. Our DC High Volume Axial Fans are best suited for high pressure situations and applications. These fans are designed for a longer service life and will be suitable for larger engine rooms with high levels of running time.
