## Questions & Answers

**Q: "Is this a true air regulator or just a flow restrictor?"**
A: The DAR03B is a needle valve regulator with digital display—it actively regulates airflow to maintain your set PSI. For diaphragm-style regulation (pressure holds with no airflow), see our DAR02B model.

**Q: "Does the display turning off affect my pressure setting?"**
A: No—the display auto-sleeps to save battery, but your pressure setting stays locked. The timer is adjustable (30 sec to 3 min) via instructions. Just tap the button to wake the display and verify.

**Q: "What's the CFM rating? Will it restrict flow to my spray gun?"**
A: Rated at 16 CFM—more than enough for professional HVLP guns (typically 8-15 CFM). Won't choke airflow or affect your spray pattern when sized correctly for your compressor.

**Q: "How accurate is it at low pressures for airbrush work?"**
A: Optimized for 10-160 PSI range typical of spray guns and pneumatic tools. For precision airbrush work under 10 PSI, consider a dedicated airbrush regulator designed for that range.
