FRIULAIR presents flanged FW filters, in carbon steel, for high compressed air flow rates.

Filter body is pre-treated inside and outside with electrophoretic coating to increase corrosion resistance. - Lower flange is provided with a hinge and handle mechanism to allow a single operator to open the vessel for replacement.
Four levels of filtration.

Filters are complete with:
Float drain SCG20 on models FWP, S, X
Manual drain MDR04 on models FWZ
Differential gauge DIG04 1

Vessel CE marked in accordance with PED 97/23/EC Directive. ASME Section VIII Div. 1 standard is also available.

Easy to read DIG04 differential pressure gauge, supplied as standard to monitor the filter element performance.

Filter body is pre-treated inside and outside with electrophoretic coating to increase corrosion resistance. External surfaces are powder coated.

Lower flange is provided with a hinge and handle mechanism to allow a single operator to open the vessel for replacement.

Condensate drain port G 3/4".

SCG20 automatic float drain supplied as standard on models FWP,S,X. Manual drain on models FWZ.
Four grades of filtration (P,S,X and Z) to cover all requirements for clean compressed air in respect of ISO 8573.1.

Only one cartridge size for each filtration grade covers all filter models.

Push on element with double o-ring for speedy replacement and air tight connection.

Screwed tie rod for cartridge fixing in stainless steel.

Each element has double (inner and outer) polyester felt sock making it suitable for high temperatures and resistant to synthetic oils.

Stainless steel inner and outer supports for maximum \strength.

Silicon free manufacturing.

Filter grade Air quality Application example Identification color
Series P
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.
3 MICRON
Series S
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.
1 MICRON
Series X
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.
0,01 MICRON
Series Z
Activated 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 0,003 mg/m³. Used in the pharmaceutical industry, for dental applications, in photographic workshops, packaging and galvanic treatments.
