(G) = Grade.
AC = Activated Carbon
00 = 0.01 micron
01 = 1 micron
05 = 5 micron
25 = 25 micron
Filter Example: ACFW44 = Activated carbon filter with 1 1/4" BSP female screwed connections, to flow up to 340 cfm FAD at 7 barg, with a maximum working pressure of 16 barg.
Element Example: 25C17 = 25 micron element, to fit the 1/2" BSP housing.

Filterworld aluminium filter housings are externally powder coated and internally surface treated to prevent oxidisation. Internal tie rods are stainless steel.
All filters, other than the (G)FW05, are fitted with a differential pressure indicator. All filters, including the (G)FW05, contain an integral float type condensate drain.
The connection to each filter is BSP parallel thread.

Pressure flow rate multipliers must be applied for working pressures other than 7 barg. Please click on the link shown above for the applicable multiplier.

*Filter housings (G)FW05 to (G)FW64 inclusive have a maximum working pressure of 16 barg at operating temperatures not exceeding 65 deg C (150 deg F) and not less than 1.5 deg C (35 deg F). Filter housings (G)FW72 to (G)FW85 inclusive have a maximum working pressure of 10 barg at operating temperatures not exceeding 65 deg C (150 deg F) and not less than 1.5 deg C (35 deg F). These filter housings can operate at higher or lower temperatures, however the maximum working pressure must be de-rated and special elements and seals may be required. Please contact the factory for further information.


Standard Pressure (16 barg) Welded Steel Housings.
(1st January 2005).

Filterworld standard fabricated filter housings are manufactured from carbon steel and are designed to work at pressures up to 16 barg* (232 psig). Each housing is CE marked in accordance with the relevant Directive, although a variety of other design codes - including PD5500 and ASME are available.

Filterworld ST grade filter elements and housings meet the requirements of HTM2022. Particle removal is down to 0.01 micron with a clean & dry pressure loss of less than 100 mbar. The element(s) must be autoclaved prior to the commencement of duty.

Pressure flow rate multipliers must be applied for working pressures other than 7 barg. Please click on the link shown above for the applicable multiplier.

*Filter housings STFW05 to STFW64 inclusive have a maximum working pressure of 16 barg at operating temperatures not exceeding 65 deg C (150 deg F) and not less than 1.5 deg C (35 deg F). Filter housings STFW72 to STFW85 inclusive have a maximum working pressure of 10 barg at operating temperatures not exceeding 65 deg C (150 deg F) and not less than 1.5 deg C (35 deg F). These filter housings can operate at higher or lower temperatures, however the maximum working pressure must be de-rated. Please contact the factory for further information. ST grade elements are designed for steam sterilisation at a temperature not exceeding 137 deg C (279 deg F) in accordance with the maximum temperatures (tolerances included) stated in BS-EN 285.


Standard Vacuum Pump Protection. Ported Aluminium Housings.
(1st January 2005).

Filterworld vacuum pump protection filters are suitable for low and high vacuum applications. The filters should be sited upstream of the vacuum pump, thereby protecting the mechanical workings of the pump. Flow rates quoted below are based upon air at atmospheric pressure and a correction factor must be applied if the air flow rate is not stated at atmospheric conditions.
