snowboard419 Posted March 11, 2014 Share Posted March 11, 2014 Planning on some on board air, I have been kicking around some ideas and have landed on trying to use the air conditioning pump but would like to hear from someone that has actually done it. The pump in my ride is a rotary vane pump and I cant find any specific info on using this type of compressor pump for air. I know that piston pumps work great but not sure about this one?

Nefarious Posted March 11, 2014 Share Posted March 11, 2014 Pump is a pump... just add some kind of oil injection to the system since there will be no refrigerant to lubricate the system, and plumb as usual. A buddy of mine did it with the wd21 compressor and had no issues with it, and soon enough I will be following suit. Link to comment Share on other sites More sharing options...
Precise1 Posted March 11, 2014 Share Posted March 11, 2014 Well, it isn't quite as convenient as an on board system but it is much more versatile. I prefer to have the AC for the 1 month out of the year I use it. Just pointing out options... B 1 Link to comment Share on other sites More sharing options...
Hytekrednek Posted March 11, 2014 Share Posted March 11, 2014 I like that setup where did you get that at??? James Link to comment Share on other sites More sharing options...
snowboard419 Posted March 11, 2014 Author Share Posted March 11, 2014 That thing is sweet, but my ac has not worked since I got the truck and I can do onboard air for much less that the refrigerant cost alone so OBA here we go, hope to have it completed by this weekend.

Precise1 Posted March 12, 2014 Share Posted March 12, 2014 It is pretty good so far... I understand what you are saying. I'm sure it had been discussed, but this is the only thread I have found so far... http://www.nissanpathfinders.net/forum/topic/30151-on-board-air-from-stock-ac-compressor/ Maybe search a bit and hopefully find something else? I like that setup where did you get that at??? James I bought it off of a member parting out his truck/supplies, I was lucky to get a lot of his stuff at reasonable prices. I can't seem to find them anymore though, so the company probably went under. Viair would probably be the next contender but research the model! Of course, almost any of these can be bolted inside an old ammo can... B Link to comment Share on other sites More sharing options...
snowboard419 Posted March 15, 2014 Author Share Posted March 15, 2014 So I got a few things mocked up and at about 2500 rpm my ac compressor will produce around 130-140 psi at a decent volume. I was able to fill my 26 gal air compressor tank to 60 psi in just a few minutes. The only things I need now are an inline oiler and separator to get the rest plumbed up. I will also need to rig up a throttle switch of some sort because at idle I only get about 30 psi, I would like an electronic set up but a bike shift/cable setup may be the most affordable way to go. I will get some pics up in the next few days. Link to comment Share on other sites More sharing options...
Nefarious Posted March 15, 2014 Share Posted March 15, 2014 Just for clarification you are using the factory r-134a wd21 a/c pump right? Link to comment Share on other sites More sharing options...
ahardb0dy Posted March 15, 2014 Share Posted March 15, 2014 How are you going to work it so the compressor receives oil (lubricant) but doesn't pass it thru to your air output? I mean you can probably use the input line going to the compressor and put an oiler inline but than you would need some type of filter on the output otherwise oil will be mixing with the air coming out. Just curious. The older style York compressors would be the best way to go but they are so big and there probably isn't a lot of room to mount one.

Nefarious Posted March 15, 2014 Share Posted March 15, 2014 In his post he mentioned an oiler and a seperator, those are the devices used in air compressor supplies to do exactly what you asked. Very common and theres about a million types. Any industrial supply outlet will carry them Link to comment Share on other sites More sharing options...
snowboard419 Posted March 15, 2014 Author Share Posted March 15, 2014 Yes factory pump is what I am running and yes the air oil separator will keep the oil out of my system and I could probably just dump the oil from the filter right back in to the oiler.

Nefarious Posted March 15, 2014 Share Posted March 15, 2014 i will be following in your route as soon as i get 240v service at my new place so i can run my welder. i need to make a custom bracket to mount my wd21 pump on my r50 engine assembly (vg33e swap with r50 accessories). can you throw up some pics when you get a chance ? i'd like to see how you did it for ideas!

In an emergency, yes, but I wouldn't make a habit of it... B Link to comment Share on other sites More sharing options...
ahardb0dy Posted March 17, 2014 Share Posted March 17, 2014 I read a thread where a guy had one of those York compressors and even without a tank was able to air up his tires relatively quick, must put out some good air volume I guess Link to comment Share on other sites More sharing options...
snowboard419 Posted March 17, 2014 Author Share Posted March 17, 2014 I routed the original high side output line around the brake booster, and was originally going to solder the copper fitting to the aluminum pipe but that did not work out at all so I used a small piece of rubber hose to make a coupling. In the center of this orange tube is where I plan on installing the Inline oil separator. Here the air comes in through the black pipe and runs through the brass check valve and into the pressure switch/manifold. both of which I pulled out of a small 120v air compressor. I dont have it piped into my storage tank or have a gauge installed yet but it works, and will even run a 1/2" impact gun intermittently. And I have a plan for an electric driven high idle setup. 2 Link to comment Share on other sites More sharing options...
Nefarious Posted March 17, 2014 Share Posted March 17, 2014 Very cool man. Nice to see the factory pump supports enough flow to make it viable! I'll be following suit once I get an a/c bracket fabbed up. Good job ! Link to comment Share on other sites More sharing options...
adamzan Posted March 17, 2014 Share Posted March 17, 2014 I'd rather have my A/C lol. But pretty cool! Link to comment Share on other sites More sharing options...
Nefarious Posted March 17, 2014 Share Posted March 17, 2014 Yeah I drive my 240sx/300zx in the summer. Pathy is fall/winter/spring vehicle and I never use a/c anyways. West coast of bc never really gets that hot. The ocean regulates the temperature pretty well. Never really used a/c, but I do inflate and deflate my tires a lot when wheeling!

tmoore4512 Posted August 14, 2015 Share Posted August 14, 2015 Interesting concept. BLAST!Now I am trying to justify doing mine! Link to comment Share on other sites More sharing options...
