High-Dust Industrial Environments
In workshops or factories with elevated airborne dust levels, the 0.01 µm borosilicate micro glass fibre media captures sub-micron particles that could otherwise clog downstream equipment. This keeps sensitive tools and instruments running smoothly without frequent filter changes.
Continuous-Duty Compressor Operations
For compressors running 24/7 in production lines, this filter's 80 mbar differential pressure ensures low energy loss while maintaining consistent air quality. Operators can schedule maintenance around planned downtime rather than reacting to unexpected pressure drops.
Seasonal or Intermittent Use
Facilities with variable air demand, such as seasonal packaging plants, benefit from the filter's robust construction that withstands temperature swings between 1.5 °C and 65 °C. It remains effective even after periods of inactivity.
Multi-Brand Fleet Consolidation
Service teams managing compressors from Alup, Atlas Copco, and Kaeser can standardise on one filter type, reducing inventory complexity. This filter fits all three brands without requiring different part numbers for each machine.
Check your current filter's outer diameter (52 mm) and body height (104 mm). If those match, this filter will fit. For Alup, Atlas Copco, or Kaeser machines, it is a direct replacement. If your filter has different dimensions, contact our support with your old part number.
The 0.01 µm rating means the filter removes particles as small as 0.01 microns, including fine dust, oil aerosols, and bacteria. This meets the requirements for ISO 8573-1 Class 1.2.1 air quality, suitable for sensitive applications like pneumatic controls and painting.
The filter has a standard 1/4 inch BSP thread for inlet and outlet connections. This is the most common thread size for small in-line filters in compressed air systems. Always verify your existing filter's thread type before ordering.
Yes. It is built to the original dimensions and ratings using high-quality borosilicate micro glass fibre media. It offers the same filtration efficiency and pressure drop as the original parts from Alup, Atlas Copco, or Kaeser, but at a lower cost.
Installation is straightforward: unscrew the old filter, apply a thin layer of oil to the new O-ring, and hand-tighten the new filter onto the filter head. Do not use tools as overtightening can damage the seal. Check for leaks after installation.
We offer worldwide shipping with tracking. Your purchase is covered by a 30-day money-back guarantee and our price-beat guarantee. If you find a lower price on an identical aftermarket filter, we will match it.
