RapidAir K3015 AutomaticShutoff 175 PSI DigitalDisplayPreset Tire Inflator Gauge

This really works good. Just set the pressure you want, press start and it fills your tires to the exact preset pressure. Works great for filling multiple tires, like on field cultivator or disk. Would definitely buy again. The only downfall is it takes 7 batteries.

Fantastic! I regularly fill large tractor tires and now I simply set the air pressure, hook it up and walk away. A real time saver! Highly recommend.

Worth every penny. Very easy to use. Looks and feels well built.

Such a time saver, as a diesel mechanic I have a lot of tires to check pressures on during PMs, this saves me so much time. I built an air manifold so I can do 4 wheels at a time and this does it no problem. Set and forget, love it. One caveat and reason for 4 stars is..I have to place it down carefully or it turns itself off, maybe the batteries slightly move when it gets bumped.

The instructions are no help, it's unnecessarily complicated. If the tire is large and the pressure is too low to start with then it gives the error beep and stops. You have to go through this several times until it decides to work normally and fill up the tire. I had hoped to be able to hook it up and walk away while it fills the tire to the desired pressure but it doesn't really work like that, sadly. Now, after less than a year of using it maybe once a month, it has stopped working completely. I changed the batteries, didn't help. Big waste of money! It's a shame too because I really need something like this that actually works!

Great tool

I bought this after having been given the gift of a Milwaukee tire inflator. The Milwaukee inflator allows you to set desired tire pressure and stand back while tire inflates. You don't have to stay down there on your knees while waiting for a tire to inflate. I thought it would be great to have the same type of inflator for use with my air compressor. I farm and have some very large tires that sometimes take 10-15 minutes to inflate using my old inflator. With the RapidAir, I can set my desired pressure and walk away for a bit while it inflates my tire. With the old inflator, I had to continuously hold the inflator on the valve stem while on my knees for a lengthy time if the tire was nearly deflated. I have a few tires that will lose air over the winter to the point where they're nearly flat. I love to be able to clip the hose on the valve stem, set my desired pressure, and let the inflator take over. It's an excellent purchase.

Would be perfect if I didn’t have a Duelly truck I had to change the tip to one that would fit the inside tire but that being said I highly recommend especially if you’re airing up trailer tires at the same time
