The EFP series fan pack is a fully integrated assembly that has been aerodynamically designed to deliver high-efficiency flow rates at static operating point 50 pascal (0.20 in-H2O) and below.

At the heart of this fan pack is the ECY series motor, and this allows customers to define single-speed, 2-speed (high and trickle), or bi-directional, whereby the reverse function can be time-defined or on-demand. Also, it is available with ECY-03 motor (variable speed control via PWM).

In the refrigeration industry, condenser and evaporator fans are traditionally powered by AC shaded-pole fractional HP motors, which will turn 70% or more of the electricity they consume ...
