The WEG 6.4 is a 6.4 HP single-phase air compressor duty electric motor built to handle the high starting load and torque that air compressors demand.
Replacing a compressor motor? Match the frame, shaft, and mounting to your existing motor — and if you change the RPM, resize the pulley or sheave to keep your compressor's CFM. Not sure it will fit your setup? Contact us with your old motor's nameplate and we'll confirm the right replacement before you buy.
Backed by an 18-month WEG limited manufacturer's warranty from the invoice date. We package every motor carefully so it arrives ready to install, and we stand behind every sale. Questions about fit or specs? Get in touch.
A magnetic starter protects this motor from overload and lets a pressure switch turn it on and off. Sized to match this motor.
