The HET fan unit is a 480 class mini fan that comes with a cooling fan. The fan unit is compatible with Wemotec fan units. The fan unit is constructed of a carbon filled plastic and aluminum.

The HET fan unit will outperform Wemotec fans due to a stiffer fan housing.  A stiffer housing will produce more thrust, better efficiency and less of a chance of a rotor blade breaking off the hub at higher rpm's.
