High-purity filtration for aggressive chemicals

Paul Boughton

Dependable and economical high-purity filtration systems for even the most aggressive chemicals can easily be implemented using the new TruFluor and TruFluor+ filter housings from the Process Filtration Division of Parker Hannifin.

With wetted parts manufactured from chemically inert solvent-resistant PFA, the new filter housings are suitable for a wide range of demanding applications, including those associated with the manufacture of semiconductors and printed circuit boards.

Available in 4-in and 10-in versions with standard 0.25-in gauge connections upstream and downstream, TruFluor housings feature a simple but rugged design, which means that they provide a long service life in even the toughest of environments. In addition, their two-piece construction guarantees easy installation and positive sealing.

For critical high-purity filtration applications involving aggressive media, Parker offers TruFluor+ housings which combine broad chemical compatibility with ultra-high purity construction. For maximum user convenience, they feature a stationary bowl and locking ring, which ensure that the filter cartridges are easy to replace, and that positive sealing is readily achieved.

TruFluor+ housings can be supplied in 10-in, 20-in and 30-in versions with a wide variety of port and vent/drain configurations. All types are packaged in a clean-room environment to eliminate the need for pre-cleaning before they are put into service.

Both TruFluor and TruFluor+ housings provide excellent flow performance with minimum pressure drop. With pressure ratings of 4.5 bar at up to 95 deg C and 5.2 bar up to 20 deg C, they can be used under a wide range of operating conditions.
