Thread: 12v compressors.

looks the goods Dave, a great start

Two comments - have you considered re-orietating the gas bottle horizontally under (or over) the mechanical bits? might make it a better "shape" for storage...

lastly, you should install an over pressure vent valve in the tank outlet, that an an oiler of some kind are the only things missing IMHO...

no requirement for an oiler the compressor has an oil housing underneath, thats why a while back I was chasing a very specific sort of ex aircon compressor (this is mostly the end result)

the blow off valve will be mounted on the pressure switch assembly that Ive ratted from a 240v compressor that was sacrificed to other bodges. (even then its not really required as the compressor stops pushing at about 175psi and the weakest item in the system is the red hose at 300psi)

the tank was mounted vertically for a few reasons

• I intend to drill and fit an Auto drain valve to the bottom of it (the tank is only ment to be a wet tank/reserve for the time it takes to move from one tyre to the next)
• making a frame to mount it elsewhere ment welding on the actual pressure vessel instead of the mounted flanges (and added weight)
• how it is if you pick it up by the tank handle it balances quite well
• If I sit it as is on the side sponson of fozzy its out of harms way and wont interfere with lashings.

the main idea is that the little air tank is a wet tank for when Im using it to fill bigger tanks (the shooter tank) or run rattle guns and to allow constant running of the motor between tyres on the CCC trip.

ah ok, all makes sense now

so what compressor is it? built in oiler etc? I assume it is a York or similar?

thats the one, york 2 pot recipricator.

the scroll ones are a bit more effecient and flow better but need the oiler on the inlet and grease conversion.

oh one other reason that the tank is where it is is that thats the distance the belt let me set the motor and the compressor at and the gap was just the right size for the tank with a couple of inches of movement back on the motor so I can sneak it inwards to replace the belt.

what's next? onboard arc welder?

or maybe a portable one:

I'd be really interested in how this goes over time. I have had the parts for quite a few years to do a similar setup - using a starter motor from a small Jap car, but I was told that starters are designed for short usage under high load and are'nt the best for the job.
I've been looking for a 12v motor for some time now, but if yours performs, then i've been badly informed.

I brought a S3 SWB years ao and is a project quietly gaing steam. Anyrate i fould when i brought it , it had a air con fitted to the 2.25 petrol motor. belt running onto it from motor. I was going to get 2 truck air tanks like a Iveco 4500 series ( due to them being short and alloy) and plumbing up the system up.

Question is why have it portable when u could fix it and have Air fitting at each end of car ( e.g suzi coil fitting from a truck)and a 5 mtr lead to do everything?

I'm sorry if has been explained at another thread or i have stuffed up your idea.

Cheers

Why????????


Good to see you recycle but would you be seen using that contraption.

Full marks for engineering though.
