Description
Product Overview
The GX PCP compressor filter is engineered for high-performance air filtration in demanding environments. Constructed from seamless aerospace-grade aluminum alloy with 10mm thickened walls, it withstands pressures up to 5800 PSI. The filter includes a dual-layer purification system using activated carbon and molecular sieves to remove 99% of oil, water, and microparticles as small as 0.01μm, ensuring breathing-grade air output. Key specifications include dimensions of 260mm x 50mm (10.23″ x 1.97″), a 21.65-inch hose, and a tank volume of 3 liters. It operates at a maximum pressure of 400 bars and features M10×1 thread and 8mm quick-connect design for broad compatibility. The set comes with a hose, filter, and five replacement cotton filter elements, all in a durable black metal finish.

Usage
This filter is designed for use with PCP compressors in various settings, including home workshops, professional airgun maintenance, and outdoor shooting activities. It is ideal for airgun enthusiasts, paintball players, and industrial users who require clean, dry air to protect their equipment from contamination.
