12V compressor

[123hotchef]

the plan is to use a inline oiler already have, sounds easy enough all I need is a pressure switch then for 12V

Don't forget that any oil sucked in will be blown out - not ideal if you're inflating tyres with it. You may need a filter on the output.

pretty much any pressure switch should do, it'll only be switching a tiny bit of current to drive a relay for the clutch

I don't know, but I guess a little one way valve after the compressor could be good too ?

Ive been slowly building up the bits to install on board air on my pajero. Im going to try using the AC pump and a converted gas cylinder as the air tank. I've got a 120psi cut off switch, 150psi pressure release valve and an inline oiler for the inlet.I think im going to use push fit 10mm air line to run outlets at the front and rear.

A one way valve is a great idea just incase. Ah good shout on the pressure switch that thought didnt cross my mind

Let me know how you get on danneh, I am doint it to my mitsi L200, I dont have AC so I need to retro fit this first. never used the push fit air line myself but do you need outlets front and rear? where u putting ur tank and what gas cylinder do you have.

yes I think I will just a cheap one I think

 

[123hotchef]

using the 16kg butane cylinder as a receiver do I need a inlet and a outlet or can I just fit a T into the top or + into the top for the in out and drain? I am thinking the pressure switch can be fitted into the feed to the receiver so it is out of harms way

 

[rtbcomp]

If you have separate inlet and outlet the incoming air will expand into the tank and cool down, thus condensing some of the water/oil into the tank.

For simplicity you could have a simple T at the bottom of the tank, but you'll probably need a better filter on the outlet.

hum i could drill and tap the tank in the side or bottom and screw another fitting in

 

[rtbcomp]

I fitted 2 pipes into one tank by using a 15-10mm reducer

 

[123hotchef]

is that a solder fitting

Any space under the bonnet for an old lorry air compressor?

 

[normspanners]

I fitted a twin cylinder compressor from a gardner truck to my v6 cortina estate mounted it on the inner wing and just pivoted the compressor on a hinge type pivot so the weight of its cylinders tensioned the belt, when I wanted air I just lifted the compressor by the head put the belt on the pullies and let the weight of the compressor hang on the belt, when I finished with the air and was ready to drive I would take the belt off and let the compressor rest on the inner wing on a rubber buffer. it solved the problem of mounting the compressor on the engine( lack of places ) and the issue of the rubber engine mounts slackening the tension off, because it was self auto adjusting. pressure was adjusted by a truck pilot unloader valve.

I had a Warn fitted to my last 4X4 and used 2 Soda Stream cylinders.

You could look for a vehicle with air suspension, not necessarily a 4X4 and whip its pump off.

how do lorry air compressors work? Electric?

 

[rtbcomp]

Yes, bog standard capillary type. There's a stop inside them to stop you pushing a pipe all the way through, this will need removing with a file &c.

The ones I have worked on have all been engine driven, belt drive or fitted into the timing chest, loads of air without a silly little electric motor flattering the battery.

found plenty of AC comporessors for my 4x4 on ebay ill just get on of those it is a easy fit then

 

[MattF]

What 4x4 do you have?

 

[123hotchef]

What 4x4 do you have?

it is a mitsi L200

Ok so I am collecting the bits I need I have the compressor drive belt tensioner, I will have the reg, I have the oiler.


I need a decent but cheap oil separator if someone can recommend one please???

it needs to work because I will have a inline oiler in the air inlet of the compressor so the oil needs to be taken out before the tank idealy
