FlexBowl™ Filter Pressure Vessel System product photo Primary L

FlexBowl™ Filter Pressure Vessel System

The FlexBowl single-cartridge filter pressure vessel system has been specifically designed for the challenging ultrapure chemical applications used in semiconductor manufacture. It meets Pall’s same high standards for cleanliness, purity, compatibility, and mechanical strength as its Megaplast™ housings and Kleen-Change® assemblies. The system’s extremely flexible design allows for easier and safer filter handling, and reduces cost of ownership.

The key to the flexibility of the FlexBowl system design is a universal manifold, which can accommodate a fully disposable capsule assembly or a reusable housing. Either of these connects easily to the manifold with a quarter turn of the locking ring.

Pall offers the FlexBowl pressure vessel system with many housing and capsule assembly options to maximize flexibility. Housings are available in 4 in (102 mm), 10 in (254 mm), and 20 in (508 mm) sizes. The 10 in (254 mm) housing is designed to fit standard 10 in (254 mm) filter cartridges with a diameter of up to 3.25 in (82.5 mm) and a nominal length of 10 in (254 mm). Standard semiconductor industry inlet and outlet connection fittings for this system are also offered in a variety of different sizes and styles.

5 The part number suffix K3 indicates that the filter is prewet and packaged with DI water. Replace K3 with K7 for the low metal ion Me-KleenSM pretreatment option.
6 The manifold and the capsule must be ordered separately.
7 Contact your Pall representative for additional information about the G3 option.
8 Add K6 to the end of the part number for the low metal ion Me-Kleen pretreatment option.
