5HP SPL Air Compressor Motor 230V 3450RPM: Does It Fit Your Compressor?

When a compressor motor dies, the pressure is on to find a replacement that bolts up and spins the right way. The motor has to match voltage, speed, frame size, and shaft. This article looks at the 5HP SPL air compressor motor from GARVEE, listed at USD 128.79, and helps you decide if it's the right swap for your 230V single-phase setup.

Quick verdict

This motor is built for a specific task: powering an air compressor that needs 3450 RPM from a 56 frame with a 5/8-inch keyed shaft. If your old motor matches those specs, this is a straightforward replacement candidate. If your setup needs a different frame or shaft size, this won't fit.

Who it suits

This motor suits a single-phase compressor that requires a compatible frame and shaft. It's rated at 20 amps and can rotate either clockwise or counterclockwise, which gives some flexibility when matching rotation direction to your pump.

What stands out

The 5HP SPL rating and 3450 RPM speed are the headline specs, with the frame and shaft details defining the fit. The motor is open drip-proof (ODP), so it's a unit to keep in a dry indoor location. Copper clad aluminum windings help keep the weight at 46.2 pounds, which is reasonable for a motor in this class.

Meaningful trade-offs

This isn't a general-purpose motor. It's marked as commercial duty for air compressors, so think about whether your use fits that role. Also, the ODP enclosure means it's not sealed against heavy dust or water spray, so placement matters. Before ordering, confirm the frame and shaft dimensions against your compressor.

One reason to choose this motor is the reversible CW/CCW rotation, which makes it easier to match a pump that spins in either direction. One limitation to remember is that the 56 frame and 5/8-inch shaft are the only fit option offered, so your compressor must already be set up for those dimensions.

Bottom line

The 5HP SPL air compressor motor is a credible replacement if your compressor runs on 230V single-phase and requires the same speed and frame. At USD 128.79, it puts a new motor within reach without requiring a major electrical or mounting change. Check the shaft size and frame before you buy, and this could be the fix you need.
