Just got my cheapo setup wired in today... Its pretty sweet. I was just wondering... I have the compressor hard wired in, and a 50' hose running from the compressor to an inflater thing with a guage.. It only sprays air when you push down the buttom, but the compressor is allways pumping air while turned on. it builds to about 50psi, then starts leaking from the quick chuck. It isnt a pressure switch thing, its just an ON/OFF switch. Is that bad for the compressor? Should I look for an inflater with a constant air flow, instead of the flow/blocked kind?

Thanks guys.

why not just get a pressure switch? i have one on my setup and i love it!

that quick disconnect is rated for much higher than 50psi. sounds like you got a bad one.

How much is a pressure switch? How does it connect?

Thanks.

 

go to your basement and look at the pressure tank for your well. It works the same exact way, but from 220 volt rather than 12vdc.

 

Sorry, I should have googled it before asking. How does it shutdown the compressor tho, when the compressor has a seprate on/off switch?

 

You'll have to wire it up so the pressure switch cuts power from the compressor when its full. What kind of compressor are you using?

 

Im using this one:

Looks like it goes right to the battery? You might need to wire in a relay because that cable is way too thick to use with the pressure switch.

Well, you said it has an on/off switch also? Is that on a wire lead? If so, you can cut one of the wires on that and run to the pressure switch.

 

Yea, it is wired straight to the batter from the tool box in the bed. I ran a 30amp fuse at the battery. Can I just splice into the positive line and wire it up to the pressure switch? Wait, then I would have to leave the compressor *ON* all the time... Hmm.

 

Where exactly are you expecting him to get a pressure reference from? This unit has no accumulator. Without a tank it is just pumping air right out of the cylinder head and right into the air connection. The switch is used to monitor air pressure in the tank to determine when it is full and shut the pump off. This has no tank so the thing will never get to a max pressure. That 50 psi he is talking about is just the residual pressure in the 50 feet of hose. It will overheat and trip the thermal switch before it would ever activate a pressure switch.
That unit is designed to constantly run and meant to be shut off by hand when pressure needs to be checked.
Says so in the instructions page 5. Not too sure this baby is gonna cut the mustard for long periods of use during the fill ups of large volume off road rubber.

 

I had a feeling it wouldn't like filling large tires.. bummer. Well, I can fill one, let it cool for 20minutes, fill the next,etc..

Actually, it fills my air bags way fast and easily, which makes it worth while, even if it cant fill tires. I guess I can get another compressor mounted in there too for tires...haha. So I need to just find a nozzle that has constant flow, rather then one with an Open/Closed button?

 

Oh, I just assumed he was running it to a tank when he said OBA.

Disregard pressure switch info then.

 

Dallas:
I am not too sure it won't work. I did not intend to rain on your parade, it could work fine, but who knows?
I was just wondering about the whole switch thing. Was not too sure what they were going to be trying to measure without a tank.
For filling your tires, I am sure you can get to a tire before the 50 foot hose fills up. Work with what you have, or just get a nozzle that has a button that opens the thing up. This way, all you have to do is hold the nozzle open until you get to the tire you wanna fill.

 

Why not get a 7-10 gallon tank and connect it to the compressor. Then you can get the pressure switch and wire it inline (best to use a relay) wit hyour power switch. That way, you can still use the on-off switch to turn it off when you don't need it, then flip it on and it will fil the tank until it reaches the desired pressure and shuts off.

With the tank, there will be little or no problem filling a tire or 4. Obviously the bigger the tank, the longer it will take to fill, but the more you will be able to use the air before the compressor kicks in to re-fill.

 

sorry i was under the impression you were running a tank. i agree... if nothing else just get a 1-2 gal tank just top store some air and have a pressure switch so that it is automatic. i dont know what i would do without my system! i was running my IR impact last night installing a gooseneck hitch on my dads truck for his b-day with it. it was GREAT
