Thread: Pressure Control unit for my onboard ARB compressor

Any reason you didn’t fit the air compressor in the engine bay? I’m getting the smaller arb compressor when my defender arrives and hoped to put it in here. I’m also considering the arb Linx system and air compressor module that does the same as your module I believe

I have the Sd6 so bugga all space under the bonnet, and a lot of heat. I have the 5 seater so lots of space under the floor in the boot - which you can't get to when the boot is full. The twin compressor and air tank take up a bit of room. Seemed like a good idea at the time and a good use for the dead space...
Also, the air line comes out at the jack storage space, which works for me. I have a 1.5 metre extension and a T piece so I can plug two hoses in and inflate/deflate two tyres at a time, front, rear or camper trailer.

Hopefully there is a bit of ventilation under there or its going to overheat if it gets a good workout.

I asked the same question at ARB and they said all fine. But, being me, I have put a temperature probe in there so I can see if it gets hot...

I had a chance to have a play. I made up T piece - thanks EnZed - so I can plug in two hoses at the same time and do both tyres on an axle at once. I also have a 90 degree elbow and a 1.5 metre extension so I can run the hose out the back if the boot is full.

To deflate from 40 psi to 26 psi took a little over two minutes for the two tyres at once - 275/55R20 - so slowish, but I can be manually deflating other tyres at the same time as it is totally set and forget.

Inflating two tyres from 26 to 36 took 50 seconds thanks to the twin compressor and pressure tank. I'm happy with that. I just attach the two hoses and press Go on my phone.

I love it! Can't wait to use it in the bush. The two hoses can reach front, rear and camp trailer tyres and I can use preset pressures or just use the + and - buttons to set the pressure I want, just like on the servo pumps, and it works the same.

The ARB accessories bag - third photo - is also ideal. I manage to stuff in:

2 x ARB 6 metre hoses - the orange ones
2 x ARB inflator hose ends plus the accessories pack for inflating Lilos and balls
1 x extra 6 metre hose - the black one
1 x 1.5 metre extender - the hose with the white bits in the photos
90 degree elbow
T piece
ARB digital inflator
Digital valve removing deflator
Air nozzle

And, there is still a little bit of space in it. Plus, it fits in the recess on the passenger side of the boot - no rear aircon.

With the extra 6 metre hose I can run it to another vehicle, put the T piece on the end and work on two their tyres if their compressor it slow.

As a bonus, the compressor is much quieter. Also, no opening the bonnet to clamp the leads for a portable compressor to the battery terminals and getting the usual "I'll call for the tilt tray" from non Land Rover people. Boy, they think they are funny...

I have just had a play in the garage to work out some rough times.

Two tyres 275/55R20 at the same time:

18 psi to 40 psi - 1:47
40 psi to 18 psi - 1:55

One tyre 275/55R20:

18 psi to 34 psi - 0:37
18 psi to 40 psi - 0:58

So, slightly faster doing two at the same time - 1:47 for two versus 0:58 for one, so 9 seconds faster, not a lot, but more convenient, and I am sure they are at the exact same pressure.
