Azure is an electronically controlled 3.3 motor (ECM) that replaces all 1/15 1/25 HP, 115/230V and 1550/800 RPM commercial refrigeration evaporator fan motors for walk in cooler/freezer applications. For 1550 RPM, this motor connects easily to the fan controller via a standard Lyall plug. For 2-speed applications, the Lyall plug can be removed and the motor can be wired directly to a separate 2-speed control module using the included second speed tap for 800 RPM. Motor rotation is set using a simple jumper wire. Azure is rated for 115V or 230V with nothing to set; plug it in to either voltage and it adapts to the correct voltage. Product Specs: Temperate Operating Range: -40 to +55 C. Multi horsepower, self adjusting from 1/15 to 1/25 HP. 1 or 2 speed operation (1550/800 RPM). Reversible rotation. Auto voltage select (115/230 V). High efficiency ECM technology. No capacitor required. UL listed. Cross Reference: Regal Beloit/Morrill: 5100, 5105, 5106, 5101, 5111, 5200, 5201, 5205, 5206, 5211.
