Marine Air Flow International

Mixed Flow Fans

Mixed Flow Inline Fans and Ducts:

Mixed flow fans are suitable when space is limited. Often used for toilets, fresh air vents, small rooms, battery cabinets and any space where our air diverters may not fit, these fans are available in a variety of sizes from 100mm diameter to 315mm diameter.

They have two speed settings, high and low and the speed is controlled via a switch on the fan.  Ducting can be supplied to suit these fans and is available in 5 meter lengths. This is the maximum length we recommend with these fans. They can be set up as a series as they pull from one side and push from the other which is how they often come to be called "blowers" or "blower fans".  

Grilles supplied with the mixed flow fans are typically an intake separator grille on the intake and a simple fashion grille on the outlet.

A full 3 year warranty is also supplied.
