Electric Air Compressor (for Model A Jobs)

[Hoogah]

Looking for advice from the wise heads here!

I'm looking at buying a S/H air compressor, having gone down this path because I want to back flush my engine and radiator, and have read here that some compressed air is a help with this process). However, in the future I may want to use a compressor for media blasting and spraypainting.

The unit that I have seen for sale locally is in the photo. This one is for sale at $70, about what I'd have to pay for a day's hire, so you can see what my brain is telling me. It is a Peerless; it's Australian made so won't mean that much to anyone UpOver! It also looks a bit rough.

We are on single phase power and I guess I'd prefer an electric motor for simplicity.

However, I am an air compressor nuf nuf, so what should I be looking for as minimum specs to do the sort of jobs that a bloke with a Model A Ford needs to do?

- Tank size
- Free air delivery (which seems to be quoted here as litres/min at 100psi. What a strange mix of metric and imperial!)*
- Motor HP
- Max PSI
- Amps Draw
- Drive (Direct vs Belt)
- Pump construction (Cast vs Alloy)
- Pump RPM (I've read that slower is better/more efficient)
- Pump cylinders (1 or 2)

I'm ready . . . . blow me away!

* Is that US gallons per cubic acre in the US?!
