Enhanced Efficiency: This PCP air compressor adopts a dual-cylinder two-stage compression design, with 4500 PSI / 30Mpa maximum pressure and 2200W high power, delivering 35 L / min high air flow rate. It takes about 3 minutes to fill a 0.5L tank from 0 to 4500 PSI and 45 minutes to fill a 6.8L tank from 0 to 4500 PSIMulti-Layer Filtration System: Equipped with an oil-water separator and gas filtration system (Activated Carbon + Molecular Sieve), this diving scuba tank air compressor effectively removes moisture, oil, and impurities, ensuring the delivery of clean, dry, and high-quality airEfficient Cooling System: This PCP diving compressor pump features an external water and fan cooling system, equipped with cooling fans, water pump, and water hoses for rapid heat dissipation, preventing overheating during high-pressure operation. (You need to separately prepare cooling water and an external water bucket.)Automatic Stop: This high-pressure paintball compressor is equipped with a pressure and temperature gauge for real-time readings. It automatically stops when the preset pressure is reached, preventing over-pressurization and enhancing operational safety and user convenienceWide Applications: Widely used in scuba diving, PCP rifles, paintball shooting, firefighting, leak detection, air - tightness testing, and more fields, meeting various high-pressure air needs. (PLEASE NOTE: Lubricating oil need use EC750 edible grade)
