Air compressor air filters, 1250 - 11,875 scfm

Reliable purity for high flow rates

F-series air compressor air filters with flanged connections have been specially designed for high air requirements. Their sturdy design and generously sized filter cases ensure a reliable stream of standard-compliant compressed air purity. They provide coverage for all purity classes as per ISO 8573-1 – with remarkably low pressure loss.

  • Flow rate 1250 to 11,875 scfm
  • Max. working pressure 232 psig
  • Max. operating temperature 140 °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 impressive performance data of KAESER FILTER products have been determined in accordance with ISO 12500 and confirmed by the independent German "Institut für Energie- und Umwelttechnik e. V.” (IUTA) testing agency.
  • Minimal pressure loss, maximum savings:
    KAESER FILTER products feature generously dimensioned 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 steel housing and a stable filter element. Threaded rods and positioning guides ensure rapid element replacement and reliable sealing of filter elements. KB and KE coalescing filters are equipped as standard with the electronic, level-actuated ECO-DRAIN 31 F Vario condensate drain

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.
