## 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.
