CHeap on board air.....

[8Mud]

I work a bit with air and other pressurized gases and liquids. Don´t know how much pressure those pumps will produce, don´t know, if they have a built in pressure fuse. Two pressure relief valves, a pressure relief valve and a pressure switch, a pressure relief valve and a pressure fuse, even if you have to install a T fitting. At even relatively low pressures, hose, lines and tanks can go off like a bomb. At least two seperate ways to shut off/relieve the pressure. A flake of rust/paint/anti-corrosive coating, in the wrong orifice and relief valves and/or pressure switches don´t work. Don´t trust a pressure switch, to control the pressure, I´ve replaced hundreds. Run away compressors are not uncommon.
Was standing next to guy that lost an eye with 60 PSI. Tank was rated at 4-5 times that.

How long does it take the two caddy compressors to fill up a tire?


And yes...safety pressure releifs are very important. I enjoy filling 2 liter plastic pop bottles with compressed air until they pop. You would be shocked how much noise they make/damage they will do. I couldn't imagine what a metal tank would do!

Check this out . It must be close to the price and at least as reliable as a couple caddie compessors.

well lets see.. $20 bucks for the two compressors.

$130 for one.. yep close in price..



with out the pressure switches I do not fill it up unattended. I don't need my back in blowing up.

Every once in a while, I´ll walk up on a pipe or tube, rated to 400 PSI or so, that looks like a hand grenade. It isn´t so much the size of the pump, as how much pressure it will build and the weakest link. A good rule, is in addition to the switch, two seperate ways to relieve pressure in a controled manner.
The OH!, chit factor sets in. Be careful.

Well when I posted, it was only around $60.00:doh:
