Martins Industries Flatematic Handheld Automatic Tire Inflator - up to 174 PSI, Inflate and Deflate automatically, Rechargeable Lithium-ion Battery - Loud signal and stop when set pressure is reach

Works perfectly. Very happy with the tire inflator. Makes airing up class 8 fleet not as annoying.

Saves time is spot on accuracy

I liked it it was working good but there is one problem after a few times it started not to work and I can’t get hold of technical support. That’s why I gave one star on overall and five star on the three items easy to use easy to read, etc.

The only thing I would like to change is that the head is quite large and it’s not fit for tight places

It works well for truck tires and farm equipment tires just set it and keep working on other things

Wish I would have bought one years ago

Best inflator I used for semi and work perfect!

Every time we use it, we have to reprogram it. Missed the return window so throwing in the trash.

We used a Martin's auto system at a previous dealer I worked at. When I saw a handheld auto, I had to give it a try. Hands down best tire inflator I could have asked for. With pricing similar to tool truck guages it has actually made me more than a manual guage would. When doing initial inspection it is easy to just set it and leave it till it beeps at you, allowing other tasks to be done at the same time as adjustment of tire pressures. Especially useful on HD trucks where there is a 20 - 30 psi difference front to rear. It not only inflates but also auto deflates and will adjust to loss after sitting on tire for a while. Would recommend 100% Also quite durable. Will add a video when I have a chance

A must have for any shop! Works well and allows you to do other things when filling tires. I put a locking end on mine to increase the slippage off the valve with the original but the original worked.

Ses une très bonne affaire et ses très précis je le recommande

I bought this as it would save me time filling tires after mounting them onto rims. I usually stand at the machine to get the proper pressure in each tire for a minute or so. This allows me to put about 5 psi in a tire and then attach this to the tire and it continues to fill up to the pressure I have set it to. Also if I need a ton of pressure to seat the bead, it does the opposite and lets air out. I checked the pressure with my manual inflator, and it was within 0.5 of a PSI to the set pressure on each tire, I'm super happy with that. My only con is that the inflator shuts itself off after a minute or so of not being used. I wish I could adjust this setting. Highly recommend this inflator!
