FILTERS FOR COMPRESSED AIR

Filters for compressed air, spin-on type. Interchangeable filter body, airflow rate up to 9.800 Nl/min. Maximum operating pressure 16 bar.

Four levels of filtration.

Friulair has designed disposable filter cartridges with the filter grade and the flow rate clearly mounted on the casing; maintenance is easy and reliability high.

FOUR LEVELS OF FILTRATION

Filtration grade	Air quality	Application example
P SERIES – 5 MICRONS	Filter capable to separate emulsion and particles down to 5 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 MICRONS	Filter capable to separate particles down to 1 micron, liquid an oil included. Maximum contents of residual oil 0,1 mg/m3	Normally used on outlet of dryers as (X) grade pre-filter. Used to prevent the deterioration of the pipes of compressed air plants, for surface treatment, on vacuum pump exhaust, on compressed air motors, and as post-filter for adsorption dryers.
X SERIES – 0,01 MICRONS	Oil removing filter capable to separate residual oil and extremely small particles down to 0,01 micron. Maximum contents of residual oil 0,01 mg/m3. It produces air technically free from oil.	Used for the protection of control system, pneumatics haulage, painting system and as pre-filter for adsorption dryers.
Z SERIES – ACTIVATED CARBON	ctivated carbon filter for the elimination of oil vapours and odour. When installed, after a (X) grade filter, it lowers the maximum contents of residual oil 0,005 mg/m3.	Used in the pharmaceutical industry, for dental applications, in photographic workshops, packaging and galvanic treatments.
