Description
Features
- Though the filter membrane is intrinsically hydrophobic, it is further processed and ultra hydrophobic, ensuring absolute sterilization under dry or wet conditions.
- Exceptionally high flow rates with low pressure drops
- Adopting temperature-resistant PP thickened core with superior temperature and pressure resistance.
- High temperature resistant, with options for in-line, autoclave repeated steam sterilization.
- The filter is 100% integrity tested before delivery and can be tested during use to ensure the integrity of the filter and the effect of bacteria removal.
Applications
- Aseptic air intake and exhaust filtration for fermenters, storage tanks, batch tanks, etc.
- Aseptic packaging gases sterile filtration
- Compressed air and nitrogen sterile filtration
- Corrosive gases sterile filtration
Quality
- 100% Integrity testing in manufacturing
- Each filter is fully traceable with unique serial number
- Manufactured in a facility which adheres to ISO 9001:2015 Practices
