These fans have a 3-wing polypropylene fiberglass blade mounted in a square injection moulded fiberglass venturi frame for easy mounting and long life. The high efficiency DC motor has a 5000 hour life at 32VDC and longer at lower voltages. This new design makes the unit more quiet while moving more air with less power. They can be operated from battery or PV direct (up to 40VDC open circuit).
