Bevpor PS
BEVPOR PS is an advanced membrane filter cartridge designed for the beverage industry to meet and surpass these criteria. Specifically developed as a beverage grade cartridge, BEVPOR PS utilizes an advanced polyethersulfone membrane configured to provide high flow and cost-effective performance. The membrane features an asymmetric pore structure that offers graded filtration throughout its depth, resulting in increased capacity to hold contaminants. The componentry is selected to maximize mechanical strength and chemical compatibility, enabling the filter to withstand repeated chemical cleaning and sterilization.

Cleaning and Sterilisation
BEVPOR PS cartridges can be repeatedly steam sterilised in situ or autoclaved at up to 130 °C (266 °F). They can be sanitised with hot water at up to 90 °C (194 °F) and are compatible with a wide range of chemicals. Capsules can be repeatedly autoclaved up to 130 °C (266 °F).
For detailed operational procedures and advice on cleaning and sterilisation, please contact the Technical Support Group through your usual Parker domnick hunter contact.
Retention Characteristics
The retention characteristics of BEVPOR PS have been determined by a combination of controlled laboratory tests and in-use monitoring for a number of organisms. Bacterial challenge testing is carried out to methods specified in ASTM F838-05.
Integrity Test Data
All filters are flushed with pharmaceutical grade purified water prior to despatch. They are integrity tested to the following limits:
Recommended Rinse Volume
Prior to use – 5 litres per 10” (250 mm) filter cartridge.
Features and Benefits
- Removal ratings from 0.2 to 1.2 micron
- Repeatedly integrity testable
- Cartridge can be regenerated and sanitised for extended service life
- Low adsorption of protein, colour, and flavour components
- Asymmetrical pore structure provides high capacity contaminant loading
