What version for Under seat ARB Twin- issues with brushless version?

Was looking to put an under seat ARB twin compressor in. I see at least three versions? Owl, Agile and XSpec? I asked about the OWL version and was interested in the new brushless version, since it’s spec sheet is pretty impressive and its the newest hotness. OWL said that the brushless has issues with over heating? Is that true. Is it just moving so much air it gets hotter?
 
The ARB brushless are relatively new to the market, so no meaningful long term reliability data as yet - I think they have been out around 6 months in AU. Their big plus is 50% increase in air output, plus lots of built in tech. The ARB video suggests it handles overheating and temp variations - at least that was my impression watching it.

The older ARB twins are almost bullet proof. I had mine under the seat for 10 years with no issues in very harsh conditions (in my Nissan Patrol). Same model installed on my Grenadier, again no issues.

These two videos may help you decide.

Is there any functional differences between the different installs? They all look pretty similar?
 
What might be very interesting is a speed comparison between the older style dual compressor and the new single brushless.

The new single brushless may give you around 75% of the old dual compressor's air capacity, for less.

And if in place of the second cylinder, you had a small tank…. Did I also read that the new twin brushless would run in single mode for a redundancy aspect?

Dual air advantages include air capacity (saving you time), durability and redundancy. But a single ARB compressor is also reliable, just slower. But the new single brushless ARB compressors have increased airflow and may appeal to the occasional user, instead of the costly dual compressor (new or old models).

If you use a multi-tyre inflate system, dual is really the only practical option. If you are doing 2, 3 or 4 tyres at once, a dual compressor is the way to go.

Just decide what meets your needs and budget the best.

I had the small ARB tank on my dual compressor in the Nissan Patrol under the seat. I switched to the larger tank in the Grenadier. My compressor is mounted in the cargo area, up high (above the ORS drawers).

They do look very similar, but there maybe fuse and wire gauge differences based on the current draw (I am still looking for the ARB brushless installation guide). Looks like a big jump in draw but also a big jump in air flow. The new single compressor is 130L/m verse 174.4L/m for the old double air compressor (comparing 12v models). The new single gives you nearly 75% of the old doubles air flow, that is impressive.

The Brushless version does not fit under the front seat, at least not when using the Owl mount. Ask me how I know…

Would the brushless single fit, maybe with a tank? The biggest I’ll have is 35s, so I would think that would work pretty well? Maybe have a simple 12V ‘consumer’ pump for back-up.

I think the brushless dual is overkill for what I need, but I like the low maintenance and the redundancy- but is wicked expensive. The brushless single seems like a nice compromise. The dual brushed won’t run in single mode, will it?

I would think the single would fit, if spun 90 degrees

Food for thought, the brushed dual is bulletproof, and the new model should make it even less expensive.

I understand, but the new BRushless is supposedly to be super-bullet proof??? I get tired of marketing that says that the new thing is perfect, when the old one was ‘perfect’. It does seem that the new one is faster. What kind of maintenance does the brushed need? Granted, I’m probably looking at tens of hours or operation a year. The speed I really don’t care, from the single brushless up, they are all fast enough. If I could find a twin old one for a good price, I might go that way.

What’s more reliable the brushless single or the brushed twin? I can’t seem to find a lot about that comparo.
