ExtremeAire Compressor Installation

By Jeep Experts

For those who have visited my website up to now, you could have browsed the ExtremeAire compressor write-up I did when MikeW and I put his ExtremeAire compressor in his TJ.  Mike has had his unit for a few years and final I knew, it was nonetheless going sturdy.  Another native good friend has used his ExtremeAire for a number of years and I do know for sure he has used the heck out of it.  When I found that one other good friend of mine, DonP, was promoting his ExtremeAire (he was upgrading to the brand new Warn winch/compressor unit), we settled on a value and I finished by his home to retrieve it as soon as he acquired it out of his Rubicon. 

There is at all times a few methods to pores and skin a cat, for essentially the most half, so I believed one other write-up on this compressor could possibly be  helpful.  Aside from the compressor, most every little thing I used to be doing was totally different from MikeW’s setup so now you’ll have a 2nd opinion on the best way to set up the ExtremeAire compressor and interface it into your TJ. 

I visited Extreme Outback’s web site to see if I may collect some information on the compressor.  The following specs are from their website: 

– Continuous obligation cycle
– 3/4 horsepower motor
– 30-amp draw at 35psi
– 40-amp draw at 150psi
– 4 cfm free movement charge
– 150psi max working stress
– Can be mounted the wrong way up
– 14″ lengthy, 6″ broad, 9″, tall

I hoped to discover a movement charge with rated stress as this offers extra information as to how properly the compressor performs underneath actual world circumstances resembling airing up a tire to 30 PSI.  I’ll put up some air-up instances as soon as every little thing is checked out. 

For what it’s price, I known as the telephone quantity on the internet website and spoke with GeorgeC, a really nice gentleman who answered the telephone.  I defined to GeorgeC that I used to be the second proprietor of this compressor, having simply purchased it from a good friend, and that I used to be making ready to put in it.  My query…..”What is the right gauge wire to make use of throughout set up.”  Since I didn’t have the proprietor/set up handbook, I believed this was a professional query.  GeorgeC inquired as to my set up and the space between the compressor and the battery.  After telling him it will be about an 8′ run of wire, he knowledgeable me that I ought to persist with 8 gauge wire and even use 6 if I may discover it.  George said that if I used to be mounting the compressor close to the battery, 10 gauge can be enough.  He additionally steered I set up a one-way examine valve (extra on that later).  I thanked him for his time and he stated that if I had some other questions come up through the set up, I ought to give him a name.  Nice man….good customer support.  Thanks GeorgeC! 

Included with the compressor was the management solenoid that Extreme Outback sells in addition to their 100 amp circuit breaker.  Thanks Don for tossing in these additional gadgets!  As the saying goes, the satan is within the particulars, and so it’s with many Jeep initiatives.  Having the management solenoid and an appropriate circuit breaker already in handcrafted this venture that a lot simpler.  I did a fast examine of my electrical components field and observed I would wish a number of connectors for the 8 gauge wire.  The remainder of the percentages and ends had been both already put in within the TJ or had been sitting on my components shelf.  On with the set up!

Since I already had my air tank mounted on the passenger facet fender within the rear of the TJ, I opted to place the air compressor on the motive force’s facet fender.  The ExtremeAire has 4 tabs, or ft, on the mounting bracket.  After wanting on the mounting location (it was not fully flat) for a bit and fascinated with how we had accomplished MikeW’s mounting, I spotted that I may bend the mounting tabs a small quantity.  By doing do, they might conform to the contoured fender floor with out the necessity for any extra brackets.  I positioned the compressor on the work bench and let the tabs (on one facet) grasp over the sting.  Slightly light persuasion with a hammer was all it took to maneuver them into an appropriate place.  Easy sufficient and no additional {hardware} wanted!

 

With the ExtremeAire bolted onto the motive force’s facet rear fender, it was time to see what I may do underneath the nice.  I already had a run of 8 gauge wire going to the rear of the TJ (which might must be prolonged by a number of ft as I later found) that began close to the manufacturing facility fuse field.  I acquired the waterproof circuit breaker from DonP out of the field and cleaned it up a bit.  As you may see, it’s rated for 100 amp.  Pushing the purple button causes the breaker to journey.  You can reset it by pushing the journey arm again into place.  The terminals on the circuit breaker are clearly marked for the battery and cargo connections. 

 

I recycled a mounting gap from another venture and bolted the circuit breaker into place.  The 8 gauge wire was linked to the AUX terminal on the breaker.  I made a ten″ lengthy 8 gauge jumper and routed it from the remaining terminal on the breaker to the suck down winch controller for a simple constructive terminal battery connection (not proven on this picture).  It was simpler than working the cable again to the battery and stored the litter away from the battery terminals on the similar time.

A couple of days have passed by (needed to go to work) and it’s now Saturday morning.  I wanted some 8 gauge wire to complete the ability run to the compressor.  Several visits to the close by NAPA, AutoZone, and ACE Hardware left me 10 gauge wire however no #8.  I finished at an automotive audio retailer positioned close to my home and located what I wanted.  They had 8 gauge wire for 99 cents a foot.  I purchased 10 ft and some ring terminals and headed for residence. 

 

I recycled a bit of scrap aluminum that was within the storage for a mounting plate.  The energy solenoid and management change was mounted on the plate and the plate then bolted to one of many bolts holding the ExtremeAire in place.  This was a fast and straightforward methodology to get every little thing up and working as I’ve a path run developing shortly and needed to strive the brand new compressor.  I’ll use one other Saturday morning to exchange the ability change with one from my bank of switches up on the middle console.  This will make it simpler to energy on/off the compressor from the motive force’s seat and assist cut back the random placement of switches my TJ appears to build up.

The wiring diagram for controlling the compressor is fairly straight ahead.  Let’s see the way it works.

1.  Let’s begin with the tank empty (no air within the sytem).
2.  The stress change will then be closed when there is no such thing as a air within the tank.
3.  When we shut the ability change (flip it on), +12 volts is utilized to the ability solenoid.
4.  The solenoid energizes and applies +12 volts to the compressor which turns it on.
5.  When the tank stress reaches the stress change’s rated stress, the stress change opens.
6.  The open change deenergizes the solenoid which turns off the compressor although the ability change continues to be on.

I used an ARB stress change (the spare I had) to manage tank stress.  I can now use this technique to run my ARB air lockers if I want because the lockers will likely be equipped with the right air stress, simply as if it had been coming from the ARB compressor.

I believed I had some air hose tucked away within the storage nevertheless it should have gone out within the one of many cleansing periods a while in the past.  A fast journey to the ACE Hardware retailer to amass some 3/8″ hose, a few 90 diploma 1/4″ NPT elbows, and a 1/4″ NPT hose barb becoming and I used to be able to go.  I’m undecided how this PVC hose will maintain as much as the temps popping out of the compressor.  If it suffers a soften down, I’ll choose up some Goodyear rubber hose from one other retailer I used to be buying in a few weeks in the past. 

 

With some Teflon tape utilized to the male threads of the 90 diploma elbow, I screwed it into the compressor head. To the elbow, I hooked up a feminine fast disconnect air becoming.  I used the producer put in becoming on the top of the hose to connect it to a male fast disconnect air becoming.  This setup permits me to disconnect the air line going from the ExtremeAire compressor to the air tank, simply in case a problem arises that requires the compressor to be disconnected from the remainder of the OBA system. 

The air tank obtained the remaining 90 diploma elbow and the three/8″ hose barb was screwed into it after each fittings had been wrapped with Teflon tape. 

A take a look at run with the plumbing put in yielded promising preliminary outcomes.  The compressor ran for a bit an then shut itself off when the tank’s stress change opened the ability solenoid circuit.  So far, so good.

It was time to see simply how properly the ExtremeAire compressor was going to work.  I hooked up a tire deflator to the valve stem on considered one of my 35″ Goodyear MT/R tires and took it down to precisely 10 PSI.

I clicked on the cease watch mode on my wrist watch and began timing the air up.  I finished as soon as at 1:30 and had about 25 kilos of stress.  The air chuck went again onto the valve stem and the timing was continued.

At 2 minutes, I finished the tire filling and checked the tire stress once more.  It was proper on 30 PSI.  I used to be fairly happy with these outcomes.  My lately retired QuickAir 2 would usually fill a 35″ tires in about 5 minutes, so the ExtremeAire compressor is wanting good.  My finish of path air-ups have been decreased to 10 minutes which incorporates getting the air hose out and placing it away.  I already just like the sound of that.

I’m ready for the one-way valve to point out up within the mail.  When it arrives, I’ll replace this write-up after which this one will likely be completed.  Nothing was shipped this previous week because of everybody being on the SEMA present. 

Good trails and bear in mind to TREADLightly!

ExtremeAire Compressor Installation

Update:  11/9/2006

The examine valve from Extreme Outback arrived mid-week.  I had gotten an e-mail from George earlier within the week stating that that they had mistakenly missed notifying me (of the SEMA induced delay) about my order and provided to ship the order free of charge.  I responded that it was not crucial however when the valve arrived, the bill confirmed free transport.  Thanks Extreme Outback for excellent customer support! 

The examine valve is a a method valve.  Air can movement by way of the valve in a single route however is blocked from flowing in the wrong way.  The examine valve is put in between the output port of the compressor and the air tank such that the air can movement out of the compressor however not again into it.  This is finished so that after the air tank is stuffed and the stress change turns off the compressor, air within the tank cannot leak again into the compressor and bleed down the tank.  It additionally permits stress within the compressor cylinder to bleed off (naturally) which makes it a lot simpler for the motor to start out afterward because it has no head stress to push in opposition to. 

The examine valve permits air movement within the route of the arrow that’s stamped on one of many wrench flats.  Be positive you take note of which manner your set up the valve.  Putting it in backwards (in opposition to the air movement) will definitely trigger a lot grief on your compressor (and potential injury).  The valve comes with a short instruction sheet that cautions in opposition to over tightening the top with the white plastic X.   Too a lot and it’ll break the valve.  I used Teflon tape on each ends of the examine valve.

 

As with the opposite air fittings, I utilized Teflon tape to each units of threads on the examine valve.  I eliminated the three/8″ hose from the 90 diploma elbow on the inlet of the air tank and threaded the examine valve into the elbow.  I then threaded a feminine air hose barb becoming onto the examine valve.  The air hose was slipped onto the barb becoming and a small hose clamp was used to safe the hose in place.

After the tank was stuffed, I disconnected the compressor’s finish of the hose.  I couldn’t detect any air flowing out which meant the examine valve was working.  An in a single day take a look at revealed that it did certainly work very properly.  The tank was nonetheless full once I checked it.
