High-Temperature Compressed Air Lines
In environments where compressed air temperatures reach up to 65 °C, such as near rotary screw compressors, this filter maintains reliable performance without degradation of the borosilicate media.
Fine Filtration for Sensitive Pneumatic Tools
When operating precision pneumatic instruments or spray painting equipment, the 0.01 µm rating ensures removal of sub-micron contaminants, protecting downstream components from wear and product defects.
Continuous-Duty Industrial Processes
For 24/7 manufacturing lines, the 80 mbar differential pressure allows efficient flow while capturing particulates, reducing the frequency of filter change-outs and minimizing downtime.
Cold Climate Installations
With a minimum working temperature of 1.5 °C, this filter is suitable for outdoor or unheated compressor rooms where ambient temperatures can drop near freezing, ensuring consistent filtration without media damage.
Check your equipment's filter housing dimensions against our specifications: outer diameter 87 mm, largest inner diameter 52 mm, smallest inner diameter 10 mm, and total height 770 mm. This filter is a direct replacement for many Atlas Copco models, but always verify physical fit.
The 0.01 µm rating indicates this filter captures particles as small as 0.01 microns, including oil aerosols and fine dust. It is classified as a high-efficiency coalescing filter, suitable for applications requiring clean, oil-free air.
The filter has a body height of 760 mm and a total height of 770 mm. The inner diameters are 52 mm (largest) and 10 mm (smallest). It is designed for in-line installation with standard pipe connections; consult your system's port size to ensure compatibility.
Yes, this aftermarket filter is built to match OEM specifications using borosilicate micro glass fibre media. It offers the same 0.01 µm filtration and 80 mbar differential pressure as the original, providing a cost-effective alternative without compromising performance.
Replacement frequency depends on operating conditions; monitor the differential pressure gauge and replace when pressure drop exceeds 80 mbar. Installation is straightforward: turn off the system, depressurize, unscrew the old filter, and install the new one hand-tight. Do not use tools to avoid damage.
