KF-Series Compressed Air Filters (F350 to F3360) - 35.4 to 336.3 m³/min

KF Series Filters

Reliable purity for high flow rates

KF-Series compressed air filters (F350 to F3360) with flanged connection have been specially designed for high air requirements. Their sturdy design and generously dimensioned 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 35.4 to 336.3 m³/min
  • Max. working pressure 16 bar (F-221 13 bar model)
  • Max. operating temperature 60°C


  • Compressed air to all purity classes:
    Six different filter grades are available for F-Series flanged filters. This highly-precise gradation enables high filtration efficiency perfectly suited to the application – with low pressure loss
  • Straightforward installation:
    The compressed air connections on the filter housings are variably selectable and fit perfectly onto the compressed air outlets of HPC KAESER compressors. This means an end to expensive on-site pipework diameter adjustments. They also deliver optimised flow dynamics with low pressure loss and outstanding filtration efficiency
  • Reliable condensate drainage: 
    Upon request, F-Series coalescence filters can also be equipped with an HPC KAESER ECO-DRAIN electronic condensate drain, which ensures a highly reliable drainage of retained condensate – all without pressure loss.

The right degree of filtration for every compressed air need:

FB Coalescence Filter
>  Intended for pre-filtration of solid matter particles and also for separation of larger quantities of condensate

FC Coalescence Filter
>  Intended for pre-filtration of solid matter particles and also for separation of larger quantities of condensate
>  For best results, a centrifugal separator or air receiver upstream is installed upstream in order to separate condensate

FD Dust Filter
>  Intended as a dust filter for solid matter particles, often installed downstream of desiccant dryers and activated carbon adsorbers
>  External to internal flow direction for superior operational reliability even with high dust loads

FE Coalescence Filter
>  Intended as a fine filter for superior compressed air quality
>  FE grade separates out solid matter particles, condensate droplets and oil aerosols

FF Coalescence Filter
>  The high-performance filter for the most demanding compressed air quality requirements of the pharmaceutical, electronics and foodstuffs industries
>  Preferably only for use with low-condensate compressed air
>  During installation, ensure that an FE filter or refrigeration dryer is installed upstream

FFG Microfilter/Activated Carbon Filter Combination
>  Combination of FF and FG, filtration of aerosols, solid matter particles and oil vapours
