CHP Series
High Pressure Air Filter

The Omega Air CHP Series is purpose-built for extreme-pressure compressed air systems operating between 100 and 420 bar. With BSP screwed connections, robust high-tensile housings, and a choice of P, M and S filter grades, the CHP delivers clean, oil-free air for breathing air panels, CNG filling stations, diving equipment and high-pressure industrial processes.

Available Grades

Filter Grades for CHP Series

The CHP Series is available in three grades optimised for high-pressure service. Together they form a complete P + M + S filtration train capable of producing breathing-quality or instrument-quality air at pressures up to 420 bar.

P
General Particulate — 3 µm
Removes bulk particulate, compressor wear debris and pipe scale from high-pressure air streams. Essential first stage before coalescing elements.
M
Coalescing — 0.1 µm
Removes oil aerosols from high-pressure compressor discharge. Residual oil content ≤0.1 mg/m³ at operating pressure.
S
High-Efficiency Coalescing — 0.01 µm
Final polishing to ≤0.01 mg/m³ residual oil. Mandatory for EN 12021 breathing air compliance and pharmaceutical HP air.
