Venting, Air and Gas Filtration Applications
Sterile VentingIncluding tanks, vessels and transport containers, autoclaves, lyophilizers, incubators, and isolators.
Sterile Air or GasIncluding biotechnical air supply, exhaust air filtration, filling and Blow-Fill-Seal operations, and transport of liquids.
Filtration ProductsEmflon® PFR Sterile Air Membrane Cartridges
These are hydrophobic, sterile filters for removing microorganisms, viruses and particles. They are integrity testable using a Water Intrusion test and validated for long-term use. Emflon PFR filters are also available in Sealkleen and Junior configurations.
Pall Advanta™ AGT Gas Filter Housings
GMP-compliant housings which support high air flow rates for economic system design.
Mini Kleenpak™ 20, Mini Kleenpak™, Kleenpak™ and Kleenpak™ Nova capsules with Emflon II membrane are recommended for single-use venting applications where gamma-irradiation is the preferred method of sterilization.
Sterile Filtration of High-Flow Fermentor Air SupplyOperation of large fermentors up to 100 m3 or more demands very high flow rates of sterile air in order to allow effective cell growth. Historically, large glass fiber towers have been used.
Filtration ProductsEmflon® PFA Filter Cartridges
Sterile filters that provide flow rates of up to 400 Nm3/h/cartridge. Small system size, low capital costs and ease of use are key benefits. The filters are integrity testable and validated to ensure an economic, safe and efficient alternative to packed towers and traditional multi-cartridge sterile air filters. Prefilters are also available to ensure long life and low pressure drop.
Venting/Sterile Filtration with High Temperature/Enriched OxygenSome processes in biopharmaceutical industry applications for sterile air filtration or venting operations operate at higher temperatures or require oxygen enrichment. Process safety may be affected if standard materials are not compatible against extreme environmental conditions.
Filtration ProductsEmflon® HTPFR Filter Cartridges
Special air filter elements with improved material resistance are able to provide safety and long service life in environments with higher temperatures or elevated oxidation stress.
