Vehicle mounted twin air compressor

archerwolf said:

Since I got the grenadier, I’ve been trying to find a good place to install the ARB twin without wasting too much space. The last few trips I’ve just been using in a pelican case and hooking it up to the NATO plug when needed. Owl Offroad just released a bracket for mounting the ARB under the drivers seat. That’s probably the easiest option but that’s where my radio is and I like having extra storage there.

On Grenadiers with the optional inverter, the inverter is installed in the left rear cargo area behind a vented trim piece. The trim is also larger to accommodate the inverter. I ordered just the left rear cargo area trim piece for the inverter option from Sierra INEOS. Underneath the trim below the rear window are 4 M6 and M8 welded nuts used for mounting the inverter. I used some CAD (cardboard aided design) and made brackets from 3/8” aluminum to mount the ARB twin. It fits just right and the vents in the trim piece give the compressor cool cabin air. There’s a channel that runs from there down to the electrical area under the seats so wiring is straightforward. I used a chassis ground and the positive is connected to a free slot in the INEOS 5 stud accessory fuse box and 80A fuse.

For air I used the ARB surface mount QD mounted directed to the plastic trim near the factory bottle jack. This way the air outlet and compressor are completely hidden when the cover is on.

Well done. The $700 for the new liner is a bugger. My install may have a checker plate extension

Indid a similar thing, though with thicker ali plate and I installed the ARB pressure control system. I haven't completed the air coupling install yet as the planning to put it to fill panel beside drawers at rear. But what have done was my same thought also

I also did the same with the 80 amp fuse. But I found some inconsistencies during compressor operation that I feel has some smart alternator issue connect. I plan to try straight off battery terminal and see if it helps.

The trim panel being expensive was an initial concern, but when you consider the cost of a bracket from blacksheep, it was a much easier decision and it uses free real estate.

The control module that is install in there presented a slight problem. I wish ineos would just have open this are up with the option to factory install, pre wire and switch a compressor and small 4l tank in this location. It is the perfect location

Twin ARB under-driver seat Owl Mount

Looks pretty slick. I’d like some kind of trim piece to keep stuff from falling into the gap between the seat frame and the mount.

Plus/minus on this kind of mount versus other locations? I guess you’d have to have your door open while you use it, which might not be good on the side of the road or in bad weather?

Is it bad that I’m disappointed that it doesn’t use one of the overhead switches?

You need to insert/remove the air hose, so you are always near the On/Off button.

For me, that space is better served for other storage needs.

Is that a positive or a negative? I’m starting to lean towards and under-the-hood mount. Would that have a switch at the pump, or one inside the cabin?

It is a nice space. I keep the tool and some First Aid kit stuff under the passenger seat. The only issue I have is that you have to get out to use it, so everyone can see what you are hiding and where, and so I’m not sure what I would use it for.

I think this is the best solution to date, I would mount it on the passenger side so you can leave the door open if pulled over on the side of a road.

I sent them an email asking if the RHD version would work in a LHD passenger seat. Seems like a better idea?

In the video text, They talk about the air compressor working better here than under the hood due to temps. That makes sense, but there are of mechanical parts under the hood…. You’d need the hood up to use, n’est-ce pas?


ETA: I see some dual compressor installs also have a small air tank. I assume that evens out the usage? This OWL install doesn’t have one. What is the downside?

While I like the underseat, I have three potential vehicles, so maybe potable would be better, I just really don’t want to screw with clamps and battery posts- but to be universal to a Jeep/4Runner/IG, clamps to a battery is about as universal as it gets.
