Review: Works great and looks to be high quality and solid - I always use upstream oil-water filters but nonetheless I believe this did an awesome job on any that might have formed in the line as I did three panels in Texas humidity and no water issues
Review: Easy to Use and No Clumps - An online video suggested we purchased this separator when we bought our sandblaster gun, seems that compressed air tends to be moisture rich. I never knew the air was that "moist" we just used it for cleaning vacuum filter housings and the sawdust cyclone in our shop. Using our sandblaster gun, I have to drain this about once an hour. This little device was easy to install, easy to drain and evidently, it works perfectly as we never have media clumping. Definitely glad we got it.

## Questions & Answers

**Q: "Will this filter leak at the drain valve or threaded connections?"**
A: Install the AI303 using 2-3 wraps of Teflon tape for a secure, leak-free seal. Precision aluminum housing prevents leaks common in cheaper filters. Includes our 12-month Protection.

**Q: "Does it restrict air flow or reduce pressure to my tools?"**
A: No. Zero performance loss. The AI303's optimized flow maintains full pressure delivery (5–150 PSI max). Handles airbrushing to impact wrenches without slowdown. You'll notice cleaner air, not slower tools.

**Q: "What fittings do I need? Will it work with my air compressor line?"**
A: The AI303 uses standard 1/4-inch NPT connections (F inlet, M outlet) for most hoses. Use a brass adapter for other sizes. Install in under 2 minutes—simply thread it inline between compressor and tool.

### ⭐⭐⭐⭐ Good Filter. Great service.
*by S***E on July 17, 2024*

The first filter worked well but there must have been a manufacturing defect because it blew apart after a few weeks. I run a 135 psi mcgraw compressor from harbor freight and the filter is rated to 150 psi. The air is very humid where i live and the filter kept a lot of water out of the line. I contacted the manufacturer and his first question was if anyone was hurt. Luckily no one was near the compressor. He proceeded to refund my money and overnighted a new filter to me. Great service!
