LE LEMATEC Digital Air Regulator for HVLP Paint & Spray Gun

Item comes with manual for detailed instructions, is able to connect with standard 1/4 inch NFT threads. However the lower adapter comes loose to push-fit the inner ring with screwed on pressure. Mechanics thread tape is needed to secure air leaks, although it became fussy and difficult to stay on as the outer NFT connection is not directly secured by the screw in, it is secured by the “differential pressure applied” by screwing it on. May be fixable by applying head to ring seal as it doesn’t come with a ring seal of its own. Other than that the functions are great and works better than originally thought. I have mine fixed with quick disconnects and reconnects to allow hose and attachments to be taken off and on. As well as an in-line filter for water and oil separation. The Psi adjustments work as well and to specification allowing lower output Psi and higher outputs as well as a button lock.

I have this unit on an HVLP gun and also the same but non-locking adjuster unit in my Iwata LPH-80 for doing Cerakote. It works very well and is very well constructed. I am now only going to be using these Lematec gauges/regulators on all my air guns. Simple to use, and appears to hold settings accurately. I've gotten acetone on one of them, and accidentally submerged the other in water during cleanup. I know it's not recommended, but they both still work like on day one.

I have this air gauge on the air assist for my laser cutter. We use it to make sure the remote compressor is working and providing enough air. Typically we run around 60PSI so it's not the highest pressure going through but it does seem to work pretty well. Up until now we've been partially opening a ball valve and guessing the pressure - now we can be repeatable about it. The lock on the pressure is also good to prevent unintentional changes. Having quarter inch threads is useful since we just installed it after a flow switch and a quick connect.

This little gauge is pretty awesome. Some may say it doesn't exactly work with pressure standards but that may be because they are working with inferior compressors. With a large compressor and knowing how much tank pressure you have definitely helps when to stop spraying or using any tool. This gauge works well to limit and know the pressure at which you are using near the tool. I like it because if you have a sensitive tool or a job you want to stay at a specific air pressure for then this works awesome.

This product works well for what it is, but it’s not quite what it’s advertised as.. It’s a simple line gauge, and will not let you adjust the PSI to your tool accurately unless you adjust it while using the tool. In other words, it has no built in diaphragm, like a true regulator would/should. I really wanted to like this product but I’d have to waste air setting the psi. And as the tank gets lower, so does the psi reading in the meter.. So it just is not accurate at a professional level. If you’re ok with constantly adjusting it, this is an ok gauge. The digital read out is nice to have. But for me, ultimately I got frustrated with it and replaced it with a true line psi gauge with a diaphragm that allows you to raise and lower the psi to your tool without any air running through it to the tool.. For reference, I got this for use with an sand blast cabinet. I cannot recommend it for this use-case. Maybe it would be better for a small etching air brush, though.

Awesome product gives pretty accurate readings, also gives working air pressure from tool your using, very easy to adjust

REVIEW CHANGED AFTER LONGEVITY!!! READ!!! Ok, so I’m a painter, in a professional shop, painting high end cars. I bought 5 of these regulators. I put one on an iwata lph400. Two on 2 SATA 5000b RPs, and two on 2 GTI pro lites. At first they seemed pretty good. Within about a month, every. Single. Regulator. Malfunctioned. All of these are anywhere from 5 - 12 psi off the mark, seems to be on the low side. If you are working in a professional atmosphere, do not buy these. They will cost you time and reshoots. You may be able to get by on a little project or something, but when your trying to match a factory finish it’s a big help to be able to trust your equipment. Just bite the bullet and buy the regulators from the gun manufacturer. I have replaced all of these crap regs with the regulators made by the respective manufacturers. Problems are gone

I used my new Lematec digital pressure gauge with my Iwata LPH-400LVX and my Fisheye filter. I used the gauge for the first time the other day. It helps if you follow the instructions just prior to using it. I first read the instructions a month before I used it and had to reread them to adjust the pressure correctly. Once you get the hang of it, it's really simple. I had some questions and concerns about the gauge, so I reached out to Lematec customer service. They were very responsive and easy to deal with. I highly recommend the Lematec gauges. Thanks

Adjustment screw completely backs out, can’t adjust air flow. Not suitable HVLP pressure regulation even if it worked
