## Questions & Answers

**Q: What tools is the ZN312 compatible with?**
A: 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.

**Q: How often should I drain the filter bowl?**
A: 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.

**Q: Will this remove enough moisture for HVLP spray painting?**
A: 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.

**Q: How do I install it correctly? Which direction does air flow?**
A: 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.

**Q: How long does the filter element last?**
A: 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.

### ⭐⭐⭐⭐⭐ good product

very good product

### ⭐⭐⭐⭐ Works great
*by J***6 on November 22, 2024*

I have a ton of moisture from compressor (separate issue) and this filter does the job extremely well. My only nit-picky complaint would be the sticker in the center of unit is difficult to remove and leaves a residue behind. With gasoline cleaned off easy though. This has no impact on functionality, just throwing it out there. Highly recommend.
