Air Compressor pressure switch Current rating?

[jm101]

Hello,
A friend recently bought a house with his first garage, and I am planning to get him a used Quincy compressor.
I found an appropriate one, looks to be about a 215 with a 1.5hp motor.
However when looking at the pictures the motor is wired straight through the pressure switch as opposed to a motor starter. I am only schooled on larger compressors where wiring a motor through the pressure switch would not work. Given the cost of a magnetic motor starter, it breaks the deal if I need to get one in addition to the compressor.
I have seen lots of little homeowner compressors, at box stores, that are wired through the pressure switch, so I guess my question is at what motor size -current- is a starter required?
I have rebuilt many Quincys, but never one this small. I figured give it a little top end refresh, inspect the bottom end, seal off any air leaks, build a belt guard, and get a new air filter setup. Should be a good compressor for him for a good long time.

Nice gift
Most pressure switches will handle that motor fine.

That compressor looks factory. It likely did not come with a mag starter and doesn't need one. We typically see mag starters starting on 5HP compressors.

If you take the top off the switch, you'll most likely see HP ratings at various voltages. As long a the motor HP is within these ratings at whatever voltage you're using, it'll work fine.

Thanks all, the knowledge commons prevail again. I will go check it out and likely drag it home.
