FFA Series Compressed Air Line Filters (23 – 1645 CFM)

The FS Curtis FFA Series Compressed Air Filters are high-efficiency inline filtration systems engineered to remove particulate contamination, oil aerosols, and moisture from compressed air networks. Designed for industrial air treatment applications, the FFA platform ensures technically oil-free compressed air suitable for pneumatic equipment, process machinery, and instrumentation systems.

Constructed with robust aluminium housings, the filters incorporate pleated high-surface-area filter elements delivering low pressure drop and high dirt holding capacity. Integrated differential pressure monitoring enables timely element replacement, maintaining filtration efficiency and system performance.

The series supports multiple filtration grades including particulate, coalescing, and high-efficiency microfilters capable of removing particles down to 0.01 micron and oil aerosols to ultra-low ppm levels. Nominal initial pressure drop ranges from approx. 0.03 to 0.10 bar depending on filter grade.

Automatic condensate drains ensure continuous removal of collected liquids, preventing re-entrainment into the air stream. Manual drain options are also available for higher pressure applications.

FFA filters are designed for working pressures up to 16 bar(g) as standard, with special configurations available up to 50 bar(g). Maximum recommended operating temperature is 60°C with minimum at 10°C.

Available in capacities ranging from 23 to 1645 CFM, the FFA Series is ideal for compressors, dryers, pharmaceutical plants, food processing, electronics, automotive, and general manufacturing industries requiring clean compressed air distribution.
