ARB twin compressor: Is a manifold required for inflation?

[LJDC]

I have installed the ARB twin compressor, which I am using only for tire inflation.

I read in one installation guide (https://arbusa.com/arb-twin-compressor-installation/) that either a manifold *or* a remote coupling is required for tire inflation.

Then I read in another installation guide (https://arbusahelp.zendesk.com/hc/e...ompressor-Installation-Guide-CKMTA12-CKMTA24-) that a manifold is required for tire inflation.

Do I need to install a manifold? I currently have a one-meter hose routed from the compressor to a remote coupling. The ARB docs are either contradictory or totally sensible in a way that I don’t understand.

Pretty sure the manifold isn't necessary to air up tires. Just put a dual comp in my buddies Gladiator and we just ran a line to the remote coupling on his fender, air up all the time with it. If you want more, like air lockers, then I think it becomes necessary.

I checked with ARB and was told it isn’t necessary:

The manifold is not required, but it does help to reduce the heat build-up from running the compressor for long periods of time.

What we've found is that if you have the coupler mounted directly onto the compressor, with nothing in between, the air hose can get too hot and actually melt the air line.

I would recommend keeping the installation as is, unless you're finding that the air hose is getting too hot.

A manifold is just a way to split the air into multiple pathways.

Cording to ARB it isn’t just that — it’s also a way to dissipate heat. Their instructions say to use a manifold situations; so it seemed prudent to check.
