Here's a fill tank I put together last month. I fill it from a 25 gallon upright Craftsman oil-free. I think it maxes at about 120 psi. I haven't run tubeless, but thought I'd share.

I had been using a small freon tank, kitted up for inflating tires, which was more than adequate for bikes, or bringing up one flat vehicle tire (great for seasonal topping off of one or two vehicles), but I retired it, largely due to it's age. Disliked the 18v Rigid inflator-not ideal. I also wanted more volume for vehicle tires. So, this

Picked this one up today at Harbor Freight for $39.99.

i converted mine to a ball valve, with a 90* swing ... instant full flow, depending on the air chuck/gun/nozzle installed...

i've used that tank for impacting blade bolts off of industrial mowers, and truck wheel lugs, etc.

drain excess water from any air tank, occasionally.;)
if no drain is provided, just tip it so that the tank's air outlet is the low point, then let'er rip.

I had the same issue years ago. I sold the one w/o the tank and got one with a tank.

I Just bought the AirShot. It worked like a charm, and doesn't take up much space to store. Great tool!

I have found that with careful installation and attention to detail, a plain hand pump is enough for tubeless.

I had my doubts when I first did it without a compressor but I was thousands of miles from home. It worked fine.

I've done it a dozen times since then. Never failed me.

I will say that if you're using narrower rims or doing an off label tubeless setup, the compressor helps. Otherwise, it's just necessary.
