HVLS & Circulators

Applications/uses for a particular fan or ventilator.

Refers to the location where a fan or ventilator can be mounted.

Transmission type of the ventilator (belt drive or direct drive).

Indicates the space relationships of windings and changing values of the recurring cycles of AC voltages and currents. The most common power supplies are either single- or three-phase.

The force that causes a current to flow in an electrical circuit. The voltage of a motor is usually determined by the supply to which it is attached. NEMA requires that motor be able to carry its rated horsepower at nameplate voltage plus or minus 1% al

The power required to drive an air moving device. Horsepower required varies with system conditions.
