Description
To meet the increasing demand for small-scale filters for laboratory use and process development, Pall has developed the the Junior B series housings. These are some of the smallest stainless steel housings on the market yet can achieve very high-flow rates using specially developed Pall SBF-style pleated cartridges. For small-scale filtration this Junior range is less cumbersome than larger housings or difficult-to-use disc holders. All styles are suitable for in situ steam-sterilization in sterile processes.
Features and Benefits
Minimal size and weight makes these filter housings ideal for bench-top use, or for installing into processing equipment, for both gas and liquid filtration up to 10 bar (145 psi) operating pressure.- The electropolished crevice-free surfaces give maximum cleanliness for sterile processes. In situ steam-sterilization and steam autoclaving up to 140 °C (284 °F) can be employed
- Housings are made of 316L stainless steel, and are therefore resistant to a wide variety of chemicals
- Maximizes product recovery, particularly important when filtering small-batch or high value products
- Plug-in double O-ring cartridges in a selection of Pall filtration media are available to give maximum filtration quality, economy and performance for individual applications
- Available in T-flow or inline styles with butt weld or sanitary inlet and outlet connections

Pressure Drop
The water flow and pressure drop characteristics refer to the empty housing only for water flow at 20 °C (68 °F). For other liquids multiply pressure drop by the relative density. The air flow and pressure drop characteristics refer to the empty housing only for air flow at 20 °C (68 °F). Flow rates relate to air (in Nm3/hour/scfm) at 2 bar gauge (3 bar (43.5 psi) absolute). Pressure drops for other pressures may be obtained by multiplying the figure taken from the bar gauge graph with the factor shown in the following table:| Working Pressure (Barg)3 | 1 | 2 | 3 | 4 | 5 |
| Factor to Apply | 1.50 | 1.00 | 0.75 | 0.60 | 0.50 |
| Working Pressure (Barg) | 6 | 7 | 8 | 9 | 10 |
| Factor to Apply | 0.42 | 0.37 | 0.33 | 0.30 | 0.2 |
To obtain the total pressure drop of a complete filter assembly, the cartridge pressure drop must be added. Please refer to the relevant filter cartridge literature or contact Pall.
