FH Compressed Air Filters | High-Performance Filtration by Friulair

HIGH PRESSURE FILTERS FOR COMPRESSED AIR 50 BARG

Flow rate: 381 ÷ 6 000 m³/h

The FH filter range for medium pressures is available in four filtration grades under ISO 8573.1.

The FH filter range for medium pressures is available in four filtration grades under ISO 8573.1. Filters are made of die-cast aluminium or carbon steel (FH*1000). Bodies are treated to resist corrosion and manufactured under PED 2014/68/UE. Filters can be equipped with a timed or capacitive drain and differential pressure gauge on demand.

Main Components

Strong cast aluminium or carbon steel construction (only for FH*1000 model) powder coated.
Filters produced in accordance with directive 2014/68/UE.

Vessel design conditions:

[*] Filtration grade: P (3 micron); S (1 micron); X (0.01 micron); Z (carbon attivo).

Filtration Grade	Air Quality	Application example
P SERIES 3 MICRON	Filter capable to separate emulsion and particles down to 3 micron.	Normally installed on the inlet of dryers. Ideal as pre-filter for on-line filters (series S-X-Z), and for vacuum pumps, pneumatic blowing plants.
S SERIES 1 MICRON	Filter capable to separate emulsion and particles down to 1 micron (series – S).	Ideal as a protection filter of the downstream line, in case of compressed air with a high oil, condensate and/or dusts contamination: as a pre filter for line filters with a superior filtering degree, vacuum pumps, pneumatic pumps for inflation, etc.
X SERIES 0.01 MICRON	Oil separator filter capable of removing oily residues and small particles down to 0.01 microns. Max residual oil content 0.01 mg/m³. Provides technically oil-free air	Normally used as a pre filter at the entrance of the dryer by absorption and active carbon filters; post filter at the delivery of the frigorific cycle dryers. Also ideal for the protection of the control systems, pneumatic transport, varnishing systems, etc.
Z SERIES Activated carbon	Activated carbon filter for the elimination of oil vapours and odour. It lowers the maximum contents of residual oil to 0,005 mg/m³	Used in the pharmaceutical industry, for dental applications, in photographic workshops, packaging and galvanic treatments.
