It's the absolute max the motor can put out for a 5 second long test.

I can also assure you that while it may say 1.8 HP that's an inflated motor rating. Yes, it costs more and it's big and heavy but in the long run it will pay off. If you want air for many uses including tire inflating you would be far better off to (A) get a bigger tank and (B) get a machine with an oil lube slower speed compressor.

If what you really want is to have an impact wrench for tire and other automotive work and not end up spending big $$$ how about looking into an electric corded one? I can tell you right off that the oil free models from Ridgid and most others are light duty and are direct drive meaning a very high speed compressor. Having used a good 1/2" impact wrench and a much larger air compressor, I would not buy that one. Welcome to the forum and I hope this helps, But anything more than that would probably be disappointing, IMHO. If you're a "Saturday mechanic" and want to swap out the "Winters" for the "Summers", you'd probably be okay. So specification-wise, I'd say that this particular compressor would have to really work hard to meet your demands. Best thing it to check the SCFM output at 90 PSI and go with something in the 7 to 10 range. especially tank-size and with at least 2 HP or better compressor. Like many small compressors of this type, it may only be 50%, which means you can run this a maximum of 30 minutes every hour.īottom line, if you're going to be using these particular tools a lot, (servicing tires or whatever,) I think I'd look at a larger unit. I see no mention in the specs as to the "duty cycle" of the unit. But even then, a long "trigger-pull" would eat up the reserve within seconds and cause the compressor to turn-on. The same compressor with a much larger tank would give you some reserve air which would be helpful.

If you were trying to swap out four tires with four lug-nuts each, that little compressor is going to come on and run the whole time you're at task and you'd be running at the absolute maximum of the compressor's ability.

plus some, as it tries to replenish the tank. So, at very best the compressor would do the trick if your particular tool was on the low end of the consumption required.īut even then, your tank is so small that you would have NO reserve air and the compressor would trip on immediately and run for whatever time you hold the trigger down. The compressor that you mention puts out a maximum of 4.9 scfm with only a 4-gallon tank. If you move up to a 1/2- or 3/4-inch, the cfm requirements almost double.

I'm not sure what the actual requirement of your particular tools are.īut for example, looking in the Craftsman catalog, a 3/8-ratchet or impact driver typically takes between 4 and 5-1/2 scfm at 90 psi, depending on the tool's model. Re: RIDGID 1.8 HP Running, 4.5 Gallon Oil Free Air Compressor
