## Description

desertcart.com: LE LEMATEC Air Compressor Water Separator & Air Dryer with Push-Button Drain Valve, 1/4" NPT Inline Moisture Remover for HVLP Spray Paint Gun, Sandblaster, Plasma Cutter - AI303-C1 : Industrial & Scientific

Review: Convenient and good value - This is a great little filter/dryer! I purchased this air dryer for use with an old 3-gallon horizontal air compressor that a friend gifted to me, and which I use for low-flow applications. Rather than installing the dryer right at the tool, where if would increase the overall size of the tool and could be snagged, or be subject to the weight of the hose, I installed it at the compressor outlet quick coupler, where it is out of the way and not subject to excessive pulling. When I'm done with the task I simply rotate the dryer around so that the drain button is at the low end and press the button to expel the condensate. Quick, easy, totally effective, and great value.
Review: Must have - works great and was easy to install. The filter has reduced the amount of condensation in my air take and seems to be well built with no issues.

### ⭐⭐⭐⭐ 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!
