Cleaner & Drier Air for More Efficient Performance
VEVOR 1/2" NPT air compressor filter regulator combines precise filtration, stable pressure regulation, and water-oil separation. With 25μm brass filter element, 5μm brass filter element and 0.3μm sponge filter, it effectively removes moisture, impurities, and particles for cleaner, dry air.
With 3-stage precision micron filter element and oil-water separation, our air filter regulator combo efficiently removes moisture and particles from the air. And the pressure control knob allows for easy pressure adjustment. (Max Working Pressure: 175 PSI)
VEVOR 1/2" NPT 3-Stage Air Compressor Filter Regulator Combo
Clean, Dry & Controlled Air for Maximum Tool Performance
Upgrade your compressed air system
with the VEVOR 3-Stage Air Filter Regulator Combo—engineered to deliver ultra-clean, moisture-free air with precise pressure control. Designed for both industrial and professional workshop environments, this high-performance unit ensures your tools operate at peak efficiency while extending their lifespan.
Why This System Matters
Compressed air is only as good as its quality. Moisture, oil, and particles can damage tools, reduce efficiency, and compromise results.
This system solves all three problems in one powerful unit:
✔ Multi-stage filtration
✔ Oil-water separation
✔ Precision pressure regulation
Advanced 3-Stage Filtration System
From Heavy Particles to Micro Contaminants – Fully Eliminated
This system uses a layered filtration approach to progressively purify compressed air:
- Stage 1 – 25μm Brass Filter
Removes large particles such as dust, rust, and debris - Stage 2 – 5μm Brass Filter
Captures fine particles and airborne contaminants - Stage 3 – 0.3μm Sponge Filter
Eliminates moisture, oil mist, and ultra-fine impurities
Result: Clean, dry, and stable air before it reaches your tools
Integrated Oil-Water Separation
Protect Your Tools from Moisture & Oil Damage
Built-in oil-water separator efficiently removes:
✔ Condensed water
✔ Oil residues
