1/2" NPT Air Compressor Filter Regulator Combo with Semi-Auto Drain, Double 5 Micron Brass Elements, Air Drying System, Compressed Air Water Separator, 105 SCFM, 0-145 PSI

Product Brief This 1/2" NPT Air Drying System integrates double 5-micron brass filter elements with a self-relieving pressure regulator to deliver superior compressed air filtration and precise 0-125 psi outlet pressure control from a 145 psi max supply. The dual filters remove liquid and solid contaminants more effectively than single-filter designs, while reusable brass construction ensures extended service life and economical operation. Achieving 105 SCFM (3000 L/Minute) flow at 90 PSI across a 41-140℉/5-60℃ temperature range, the system features a reliable semi-auto drain that operates without power—offering lower lifetime costs and simpler maintenance than electronic alternatives. The impact-protected polycarbonate bowl enables visual condensate monitoring, and the comprehensive installation kit includes a 0-150 psi gauge with bracket, air coupler & plug kit, two 1/2" NPT fittings, and thread seal tape for immediate industrial deployment.Specification： - Air inlet size: 1/2" NPT - Flow: 105 SCFM (3000 L/Minute) @ 90 PSI - Max working pressure: 145PSI(10.0BAR) - Operating Temperature Range: 41-140℉/5-60℃ - Drain type: Semi-Auto Drain - Body material: Aluminum Alloy - Filter element material: Brass - Bowl material: Polycarbonate (with Metal Guard)Package Contents: - 1 × 1/2" NPT Air Drying System (Double Filters & Regulator Combo) - 1 × 0-150 PSI Pressure Gauge with Bracket - 1 × Air Coupler & Plug Kit (1 pair) - 2 × 1/2" NPT Fittings - 1 × Thread Seal Tape - 1 x User ManualProduct Usage Notice: - Pre-Installation Requirements: Verify component specifications meet maximum flow demands. Thoroughly cleanse all ports and fittings to prevent contaminant ingress. Confirm airflow direction matches the arrow indicator and ensure port/thread compatibility. - Pressure Regulation Procedure: Lift the adjustment knob—rotate clockwise to increase pressure, counterclockwise to decrease. Upon reaching the desired setpoint, fully depress and secure the knob to prevent pressure drift and potential seal leakage. - Semi-Automatic Drain Management: The mechanical drain assembly automatically opens at zero pressure and closes during operation—requiring no electrical power. When condensate exceeds the bowl's upper limit, manual drainage is necessary to maintain dehumidification efficiency, delivering superior reliability and lower lifetime costs versus electronic auto drains. - Gauge Integrity Check: Ensure the pressure gauge is firmly mounted to the main body. During adjustment, observe that the needle responds smoothly without fluctuation or hesitation. - Initial Startup Note: First-time installation may exhibit temporary air discharge due to initial internal/external pressure imbalance. This is normal venting—not leakage—and will stabilize within minutes. - Operational Precautions: Always tighten fittings with a proper wrench to prevent leakage.
