Oasis Manufacturing XD4000-12 air compressor Reviews & Ratings

This is the 2nd one we own need I say more.

The compressor is very high quality. It was installed in a small fire rescue truck to operate air horns. The unit is set up to run only air horns. There is no tank on the truck and so far there has been no problems.

Customer is very happy with the outcome.

For field servicing of our pneumatic tools, we have found Oasis Air Compressors to be superior to anything that we have used in the past.

For reliability and serviceability there is no substitute for Oasis.

Look at how your compressors have helped us: it used to take us an average of 18 minutes to change a flat with a 4-way wrench.

With the compressor and impact wrench it takes us less than 7 minutes (start to finish). When you work on the highways with 60-plus mile per hour traffic this setup reduces our exposure to high speed traffic by 62%.

Talk about a safety story, not to mention that it’s less wear and tear on the body.

I got this compressor just a few days after ordering it. I have not used it a lot but it seems to work very well and is much quieter than I thought it would be. I used to have a gas powered unit on my flatbed truck and this is so much nicer. I mounted it in an underbody toolbox and have all my bed space back. I purchased an 8 gallon tank and mounted it under the bed.

The only complaint I have if you can even call it that is the power cables are ten feet long. Mounting the unit anywhere on a pickup bed or in the tool boxes on a flatbed is going to require 14-15' of wire unless you have a regular cab. The included wires are 4ga and the manufacturer says you can go up to 20' by switching to 0ga wire which I did. I used 1/0 welding cable. The ground wire is easy to bolt on to the motor but the positive is attached somewhere inside the compressor and you can't get to the point where it is attached without totally disassembling it and the case is sealed with tamper resistant stickers that say warranty is void if you open it.

I called Oasis and they said to cut the positive cable about 6" away from the motor and splice it to the 0ga which I did and it works fine, but is not as clean of an install as I would have liked. Splicing the huge wires isn't exactly easy either. Oasis's preferred method is to use their 10' cables and cut them as short as you can or mount a second battery just for the compressor right beside it. I didn't have room for this so I went the longer cable route. I would guess most typical installs will require 15' or so of cable so it would have been nice if they included that much of the heavier gauge wire from the factory. Unless you are mounting it in a Jeep or adding a battery the ten foot cables are not going to be long enough.

Overall I give it an A+ though and wish I would have bought one long ago. I have been through three gas powered units in the past ten years they just don't seem to last long mounted on a truck bed out in the elements. I am looking forward to having my bed space back and not running out of gas on the compressor or fighting with starting it on cold mornings.

I have it installed in my farm work pickup with a 3 gallon air tank. It will run a 1/2 inch impact to change sprinkler tires and bloiw out radiators and air up truck tires.

I could not do without it. This is our third one! it does not take up a lot of room like a gas powered one.

These are very durable compressors!

We just finished putting our new service truck together, so far the compressor is everyyhing we expected & are very pleased. thank you, Todd Brown

I bought this compressor for my mobile detailing company so we have enough air pressure to blow the water out of the nooks and crannies of the car after it has been washed.

I have my compressor hooked up to a 4.5 gallon tank and the pressure is set at 140 PSI. It only takes a minute to pressurized the tank from 0 to 140 psi.

We have even run an air ratchet off of the setup with no problems!

Yes its pricy, but for a mobile unit that runs off of 12v it blows the doors off my 120v 5hp home compressor.

I plan to buy a second one to mount on my 4X4 here soon.

Won't run a half inch air impact without a tank like they claim but really nice nonetheless.

Very let down, will not run a quarter inch impact except for a 3 second burst, in other words when the hose is out of air it's over. Must have a tank, it does not come with a pressure cut off switch. In other words it will blow the hose and keep pumping. You can buy better or just as good for half the price.

Mine have metal shavings when looking down inlet Hole. This can nor be right?
Its just installed and just ran a couple of minutes. Not impressed AS ive know another one who has this and the same with his. Its got oil. Was bled in the crank before use and all instructions is followed.

Works very good...needs a lot of power.
