Description

LE LEMATEC: Leading and trusted in air compressor tools. Experience unmatched quality and innovation. Experience smooth, efficient sandblasting with LE LEMATEC's advanced tools. Perfect for precise, clean results every time. Le Lematec Sandblasters in Action on Restoration Wonders Le Lematec Sandblasters at Work on Flawless Surface Cleaning Breathing New Life into Classic Treasures The LE LEMATEC logo symbolizes excellence in air compressor tools, embodying innovation and precision. Representing top-tier pneumatic solutions, it's ideal for professionals and DIY enthusiasts. This emblem signifies reliability, enhancing productivity in various tasks with advanced functionality. Watch moisture collect in the clear bowl as you get bone-dry, oil-free air. The ZN312 1-micron filter removes debris from your line, protecting your spray guns and extending tool life. Quick push-button drain included. No confusion, no guesswork. Watch how the transparent chamber traps moisture in real-time while your tools stay protected. Install in under 60 seconds, drain with one press. Stop fish eyes & blemishes. The ZN312 delivers dry, oil-free air to your HVLP spray gun for professional-quality finishes every time. Moisture causes erratic arcs. The ZN312 ensures clean, dry air for consistent, precise plasma cuts through steel, aluminum, and stainless. Moisture ruins airbrush details. The 1-micron filter captures invisible particles, ensuring pristine air for models and custom artwork. Extend tool life. Oil & moisture cause premature wear. The ZN312 acts as a first line of defense for impact wrenches, nail guns & drills. What tools is the ZN312 compatible with? The ZN312 fits any 1/4" NPT air tool: spray guns, plasma cutters, airbrushes, impact wrenches & nailers. Operating at 2-150 PSI, it covers almost all home and professional compressed air needs perfectly. How often should I drain the filter bowl? Drain frequency depends on humidity and use. Check the clear bowl: if water hits the 1/3 mark, press the drain button. In humid conditions or for critical tasks like spray painting, drain before every single session. Will this remove enough moisture for HVLP spray painting? The ZN312 is a great first-stage filter for water, oil & debris. For most hobby/light pro painting, it provides huge improvements alone. For professional spray painting in humid areas, pair it with a desiccant dryer. How do I install it correctly? Which direction does air flow? Follow the flow arrow. Air enters the FEMALE inlet and exits the MALE outlet. Apply 2-3 wraps of Teflon tape to all threads. Hand-tighten, then add a 1/4 turn with a wrench. Full installation takes under 2 minutes. How long does the filter element last? The 1-micron filter is reusable. Clean monthly with warm soapy water and air-dry completely. With proper care, one element lasts 12+ months. Need more? Replacement elements are available in our Amazon store. ZN312 Air Filter Inline Filter AR-02 Air Regulator Premium Sandblaster Hose Fitting Kit

  • Easy to use, install, and maintain.
Size: 1 Count (Pack of 1) Style: Standalone
I picked this product for the ease of use and reuseablility. It has the schrater valve to release the mositure build up which can be operated with a finger. It came with the fittings I needed to connect it to an air hose and it was really easy to use and install. It is durable and has held up to my abuse of it. ... show more

  • No moisture
Size: 1 Count (Pack of 1) Style: Standalone
My compressor lines have moisture when running my big tools; I only use this separator/filter with my paint guns. Haven't had any water drops in my paint, but I haven't had to clear any water from this trap either... strange. I have >100hours without any droplets.

  • Keeps my pneumatic tools rust free and lasting
Size: 1 Count (Pack of 1) Style: Standalone
Received very fast in the mail. Package was in good condition and brand new. It fits perfect on my compressor hose. I'm in the middle of building a fence and cannot wait to use this. No more having to drain the water out of the bottom of my huge compressor and my pneumatic tools will no longer rust and will last much longer. This was a very good buy and I recommend it to anyone that wants to keep there tools clean, nice, and lasting. ... show more

  • Poor quality
Size: 1 Count (Pack of 1) Style: Standalone
Terrible quality. It failed just a few days after the return period. I purchased this to use with my plasma cutter. Total compressor run time with the product installed was about 2-3 hours under pressure over a 6-7 week period.
