Single Hi-Flow
Incorporating an aerodynamic inlet and unique design outlet transition cone with straightening vanes that remove the vortex from the outlet flow, the single axial Hi-Flow, Hi-Pressure radiator cooling fan ensures the vehicle is maintained at normal operating temperatures during testing. Available in voltages from 220VAC Single and Twin Phase to 440VAC Three Phase. Air flow is typically 14,000 cubic feet / minute, 6,600 litres / second. Automatic switching is computer controlled, the switching point predetermined by the dyno operator.

Dual Hi-Flow
The dual fan unit incorporates two Hi-Flow Hi-Pressure axial flow fan units. One high-flow fan for radiator cooling and a high mounted fan of the same capacity for controlling engine compartment temperatures and the supply of air required for top mounted intercoolers. Both fans feature an aerodynamic inlet and a unique outlet transition cone which removes the vortex and directs the concentrated air flow to the desired point. Each fan is computer controlled and switched independently. Switching point for each fan is programmable by the operator. Combined air flow for both fans is typically 28,000 cubic feet / minute, 13,200 litres / second. Available in voltages from 220VAC Single and Twin Phase to 440VAC Three Phase.
