Also, since the leak was on the output side, it only leaked when the regulator was open, there was no observed leakage when the regulator was closed which is much more important to me. Pressures seemed to be somewhat accurate based on the behavior of my sprinklers, but I don't have a way to check super precisely if that's important to you. Review: Excellent point of use regulator. - Works awesome to regulate the air down for my Co2 laser. I but a valve right behind it and viola, perfect. ## Features - Thread: 1/2 NPT - Rated Flow: 141.2 SCFM(4000 L/min) under the pressure of 0.7MPa - Temperature Range: 5~60 ℃(41-140 ℉) - AW Series air filter regulator combines a filter and regulator into one unit, it’s more compact and with smaller mounting space - Brass filter element with 5 micron filter standard- excellent filtering performance and much longer working life - It has good performance in air filtration and pressure regulation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08B3CK1FF | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #2,898 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Compressed Air Regulators | | Color | Aw | | Customer Reviews | 4.4 4.4 out of 5 stars (1,038) | | Date First Available | June 11, 2020 | | Item Weight | 3.15 pounds | | Manufacturer | China SNS Pneumatic Co.,Ltd | | Material | Aluminum | | Package Dimensions | 11.57 x 5.47 x 3.74 inches | | Part Number | AW4000-N04A | | Size | 4000-N04 | ## Images ![1/2”NPT Compressed Air Filter Regulator Piggyback Combo, Semi-auto Drain, 5 Micron Brass Filter, Gauge and Bracket, Poly Bowl with Metal Guard AW4000-N04A - Image 1](https://m.media-amazon.com/images/I/61Ocfi8wlzL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Minor leak at output, but worked for sprinkler blowout *by T***. on December 3, 2025* This had very minor leak on the output side (even with teflon tape) but it worked well for me to regulate air out of a portable tank (that doesn't have a regulator) for blowing out my sprinkler lines.
