Air compressor reservoir??

[Nelspeth]

hiya folks, iv been weighing up the options of air compressors.
I know the majority go with the ARB compressor, unfortunately the budget won’t stretch to that luxury and as here in the uk ‘airing down’ is quite a rare occurrence I can’t justify the cost for how much it will be used.
My options are a cheaper version of the ARB, a T-max, still well respected and widely used, or a compressor with receiver tank attached like the kind used for air suspension systems.
My thinking is that I would always have a reserve of air in the 6litre tank for whatever is needed..
What’s your thoughts and opinions guys??

It sounds like using a compressor is a rare for you, so why the need for an air tank? Why not invest in a good compressor that provides air on demand? The tank is nice to have when you need large volumes of air. For airing back up my 33s and general air compressor use, my Vaiar unit works like a champ. I store mine and it attaches to my battery, but it would be more convenient to have it hard wired. A buddy hard wired his and installed it under the seat of his JK and I’m thinking of doing something like that myself.

Previously, I used a hardwired QuickAir, but when I failed after 12 years, I went to a portable one that connects via clips to the battery.
My thought was if someone other than I needed air, I could connect to their battery which could also be helpful if I couldn’t get my vehicle to theirs like on a tight trail.

I'm presently working on a similar project. I'm going to use an aluminum/carbon fiber wrapped used air tank. It's rated at 4500 psi, even with expired certification it's more than I need, that weighs next to nothing. It'll be mounted with quick fist clamps.

A reserve air tank is totally unnecessary for your application and 99% of people. If you're looking for a project or got the mod bug that's one thing, but a portable 12v compressor with alligator clips is all you need...

Are you planning to run air tools? If so, the tank will be necessary with a compressor of that size. If you are just going to use it for filling tires then then tank is unnecessary.

lots of good points guys.. and yeah as you say the tank is not really needed. The only things I need air for apart from tyres are a solar shower that runs on about 30psi and diff lockers.. but not got those fitted yet!
What I do have that needs air can easily be supplied by a stand alone compressor

Get a higher duty cycle compressor. No tank needed.

If you are going to run arb air locker or similar you will need a tank of some sort. I don't think an on demand type would hold pressure in the line to keep your locker engaged. I am pretty sure ARB requires constant air pressure on the locker. So at least a small reserve of air volume would be required. But for a shower cfm of air may be more of a concern than pressure. Not sure though I've never looked into the requirements of them.

You don't need a tank for an ARB locker. You run them right off the compressor with a solenoid. Putting one in this week.

Good to know mine is about 15 years old and has a tiny tank built into the compressor that the solenoid is threaded into. Makes sense that they would have updated the design in that amount of time. Mine is old and slow to fill tires. I'd be curious to know how the newer ones perform. Might be time to upgrade.

That's how this one is. I only will use it to fill tires and run a rear locker. But with research thats all that is needed. If you want to fill quicker and have front and rear lockers then the dual pump ARB is better. I didn't need that. They also sell a smaller pump just for lockers. But yeah...the solenoid is screwed into a "mini tank" but as long as the compressor switch is on and so is the locker then it will keep constant pressure. It may need to kick on to keep the locker locked...but OK. I'm not going to be filling tires while the locker is on.

You definitely don't need the tank. When selecting a compressor, you want the highest CFM (cubic feet per minute) rating and longest duty cycle. What size tires do you have, and what PSI do you run on trail/street?
