💨 Streamline Your Air Flow Control with ARO R37221 100 Air Regulator Gauge Review

As a hesitant buyer, I was pleasantly surprised by the quality of this air regulator. It works great for my industrial and scientific applications, and I've noticed a significant improvement in the air quality. Based on my experience, I highly recommend this product for anyone in need of compressed air treatment. The one con is that it's a bit pricey, but it's definitely worth the investment for the improved air quality.

This regulator holds the set outlet pressure better than any regulator I've seen. For example, if you set the outlet pressure to 60psi when the tank pressure is 80psi, the outlet pressure will be 60psi even if the tank pressure increases to 150. With every other regulator I have used the creep outlet pressure as the pressure in the tank rises. increases.

I bought this regulator to replace the regulator on my California Air Tools compressor that failed (split diaphragm) 60 days after purchase. I'm not a pro at these things, but I'm a DIY toolmaker. This is a durable regulator that doesn't leak at all; after two days the manometer does not catch my eye. Side by side it's much stronger than what I had before. Likes: Sturdy construction and lockable handle. Dislikes: Not yet.
