EJ22 aircon compressor for Endless air??

SuBaRiNo · Post by **SuBaRiNo** » Sun Aug 27, 2006 4:31 pm

Anyone seen an ej aircon compressor set up for endless air??

My understanding is that if it's done correctly and with a use of a tank you can opperate air tools with it.

I have also heard that some aircon compressors are oil lubbed and oil spits out of the air output of some aircon compressors. Is an ej22 one like this??

Anyone know anything about it or have done it??

I can't speak for an EJ pump but I've seen it done to an EA one. When I say "done" this was basically just that the guy had hooked a hose to the outlet of the compressor and that was it. Worked well by all accounts!

Definitely the use of a pre-set pressure valve and a tank (an old Scuba tank would be ideal) would be the go!

What about lubrication for the compressor bearings? Isn't there some process by which the compressor is lubricated? Is it perhaps a total loss blow through system (with an air line mini oiler?).

To do it you mod the compressor. Basically you pull it apart and change the open bearings which use the oil / gas for lubrication for sealed bearings which do not need lubrication.

It depends on the model of compressor as to weather you can do it or not.

Sounds easy enough... might give it a go.

my mate just bought an lseries (ea82) that has this setup with the standard aircon pump hooked up to a tank in the floor compartment of the boot. seems to work pretty well.

AP is your question... why someone would have a air tank in there car??

If yes... then for a few reasons... mainly so far i have found being able to use an air blower at high PSI to force beach sand out of the car and out of tyre beads awesome... also if your tyre was to roll off the rim and u require a lot of air quickly to put it back on then tank can supply that. Lastly there is something mighty cool about being able to inflate your tryres faster than then inflaters at service stations.

My first compressor was an old Icecream truck refrigeration unit - which obviously recirculated refrigerant. - they do need luberication but - I had a vertical output, with a very small bleed off at the base ( with a 1 way valve) that returned any excess oil to the inlet side, thus any oil recirculated. gravity still works under pressure. It is only interupted by flow - ie: when there is air ''racing" into the tank, oil will still go along the line with the air. The start, being vertical , and having a kind of oil trap, still works, as the oil just runs back down the line into the trap.

You will still need some sort of decompression valve for the end of line - as in a std compressor, to take the air pressure off the compressor - or it will never start up with load on it.

yeah inflates a tire really quick. Can run airtools for a bit. The tank is only about the size of a scuba tank. But it is back up to pressure in about 30 seconds at idle. And alot quicker if you give it a rev.

Just to let u guys know since this is an old thread... i now have done this in my car with an inline oiler and oil/air seperator so all is good... just got some wiring to do and she is complete. Compressor also needed to be dismatled and internally greased. There is no way the EJ compressors will do this by solely changing the bearings.

Nice dave, got any pic of the set up?
