OIL-Xplus 0003G Compressed Air Filters
Grade AO General Purpose & Grade AA High Efficiency
Coalescing & Dry Particulate Filters
Grade ACS Oil Vapour Reduction Filters (8mm Push In)

High efficiency compressed air filters for applications requiring very low flow rates, up to 11 m³/hr @ 7 bar g, with a maximum operating pressure of 10.5 bar g.
The Parker OIL-Xplus 0003G high efficiency compressed air filter is available in coalescing filter grades AO, AA & AX for the removal of water and oil aerosols, solid particulates and micro-organisms, grade ACS for oil vapour removal and grade AR dust filter for the removal of dry particulate and micro-organisms.
Widely used throughout industry, compressed air is a safe, powerful and reliable utility which can be the most important part of any production process. All compressed air systems use atmospheric air, which is highly contaminated with dirt, water vapour, unburned hydrocarbons and bacteria. Additionally, the compressor can add wear particles and oil from its lubricating system. The OIL-Xplus 0003G is ideal for providing contaminant removal to compressed air used in applications requiring very low flow rates, up to 11 m³/h @ 7 barg.
