Century Catalog # B381

The electric motor is manufactured by Century. The Brand name is Century (AO Smith purchased Century several years ago).

This is a Brand New electric motor with 1 year Factory Warranty, shipped in the factory box.

The ("SPL") electric motors are typically used on "home" air compressors.

Cause for premature motor failure is improperly sized wire supplying power to the motor. If the wire run is long, and the wire is too small it will cause the motor to draw excessive amps, especially on startup, causing the the internal motor start switch to arc and fail, eventually burning up the motor. Remember, on initial motor start up, the motor can draw as much as 4 times the rated motor name plate amperage for a few seconds. We recommend the motor be installed by a "qualified" licensed electrician.

Another area to watch is dirt, paint, oil, saw dust and other material in the air that might get sucked into the motor.

A properly installed motor will last for years, normally motor failure is caused by an outside force, such as the power supply, belts too tight or misaligned and a burned up motor is the result of that.

This is a single phase electric motor.

Our motors are current stock, not surplus or reconditioned.
