Inline compressed air filter series, to 1130 scfm


Cost-effective solutions for optimal compressed air quality

Kaeser inline compressed air filters are the key components for producing compressed air to all purity classes as per ISO 8573-1—and all with exceptionally low differential pressure. Moreover, their service-friendly design not only allows simple, error-free opening and closing of the filter housing, but also enables quick and clean element changes.

  • Flow rate: 20 to 1130 cfm
  • Max. working pressure 232 psig
  • Max. operating temperature 150 °F

Your advantages

  • Standard-compliant purity:
    The KAESER FILTER range uses modern deep-pleated filter media to remove particles and aerosols. A highly effective carbon fiber mat traps oil vapors. The outstanding performance data of KAESER FILTERS were calculated according to ISO 12500 and validated by Lloyd's Register, the independent certification organization.
  • Low pressure loss – high savings:
    KAESER FILTER products feature generously sized housings and filter surfaces, innovative flow dynamics and high-performance filter media. They feature up to 50% lower pressure loss than other available filters – a value which remains virtually constant over the entire service life of the filter element. This means lower costs and CO2 emissions as well as reduced load on upstream compressors.
  • Service-friendly design – straightforward handling
    KAESER FILTER products feature a corrosion-resistant aluminum housing and a stable filter element. The practical bayonet lock ensures automatic positioning of the housing and element seals, which prevents the filter housing from being sealed unless a filter element has been inserted. A locking screw prevents unintentional opening of the housing when under pressure and also provides housing venting.

Life cycle cost savings

Pressure loss is the most significant factor affecting the efficiency of compressed air filters. KAESER FILTER products feature generously sized housings and filter surfaces, innovative flow dynamics, and high-performance filter media. These features result in up to 50 % lower pressure loss in comparison to other typically available filters. Moreover, this outstanding filtration performance remains virtually constant throughout their entire service life. This reduces the load on upstream compressors, thereby offering the potential for significant reductions in costs and CO2 emissions.
