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
