Reviews for NITRA Pneumatic Air Preparation

Bring back the old version! These new units, with the twist-lock style gauge and opposing plug, are super junky. They are so tightly locked on to start with, that I needed pliers to 'unlock' the plug side, and almost broke the guage in the process of removal. The tiny plastic tangs that 'lock' these items in place do not look very strong, and I can just picture one flying off with 50PSI of pressure behind it: Not safe at all! Also, if the gauge (or plug) is broken, you may as well throw the whole thing out, because there are no replacements. Bring back the old style where I can add the threaded port for a normal gauge, and things like metal screws are used to secure pressurized add-ons.

Woah woah woah! These new style gauges are nearly impossible to read compared to the previous style. The new lens, reflection, glare, size of numbers and cannot read from an angle. I can already hear my customers complaining.

These regulators are defective on delivery. They have small set screws that hold the gauge and back plate in place that are stripped. This defect wont allow you to reverse the flow direction.

I can concur with the previous review on quality. I have had one of these fail in the field after only a few months of use. Replaced and has not been an issue since so I am hoping it was an isolated event. Other than that they are my go to for safety use in pneumatic systems. Quickly bleeds air on an emergency stop or loss of power and the soft start prevents actuators from hard crashes and or moving at dangerous speeds on startup. To be fair, I have at least 5 of these in various machines and I have only had a problem with one unit.

I would recommend this for most users, I just wish the lockout would support a larger diameter shackle for a normal lockout standard. I have typically seen in use, Master Lock - Keyed Different Nonconductive Lockout Padlock - 1-1/2" Shackle Clearance, 1/4" Shackle Diam, 1-3/4" Body Height x 1-1/2" The lock that comes with the unit is...pretty (with the flower).. but not quite a standard that I have encountered
