A full range of Filtration Solutions for all Sterile Gas applications

Sterile air and gas filtration is essential for preventing microbial contamination in food and beverage processing, pharmaceutical manufacturing, and other critical applications. Sterile gas filters remove microorganisms from air and process gases, ensuring that ingredients, products, and equipment remain protected from airborne contaminants. Coalescing filters, are the preferred prefiltration to ensure removal of liquid aerosols and fine particulates from compressed gases. These enhance the performance and service life of sterile gas filter by reducing the contaminant load, ensuring maximum protection in sterile gas applications.

Compressed Gas Sterilisation

Sterilisation of gases is especially important in fermentation, diaries, breweries where substantial amounts of compressed gas are in contact with the product. Sterile gas filters ensure that microorganisms or bacteria are not introduced to the product when it encounters the gas. SurePore Gas membrane filters are used to remove microorganisms, bacteria, and viruses. These are PTFE membrane filters that when running in dry gas conditions filtering down to 0.02 micron. These are provided in a range of cartridge formats and capsules that allow applications all sizes of to be treated. Healthcare and pharma prefer using membrane gas filtration. Also used are PurePore GF Air pleated depth filter cartridges which have superior flow characteristics compared to PTFE membrane, reducing either initial capital cost or reducing running costs.

Coalescing Prefiltration

Coalescing filters are indispensable for maintaining the purity and quality of compressed air systems, offering a range of key benefits. Firstly, they excel at removing contaminants, including oil aerosols, water vapor, liquid droplets, dust, dirt, and other particulates, thereby ensuring air of superior cleanliness and dryness. This enhanced air quality is particularly crucial for industries like pharmaceuticals, food processing, and electronics manufacturing. Moreover, by eliminating these contaminants, coalescing filters safeguard sensitive equipment such as pneumatic tools, machinery, valves, and more from wear, corrosion, and clogging, consequently extending their lifespan and reducing maintenance costs.

In gas filtration there are two key contaminates we need to remove prior to final sterile gas filtration. Firstly, condensate that forms in the transfer lines of the gas if there is any reduction in gas temperature. Secondly, oil and particulate that may already contaminate the gas, dependent on its source, or is added to the gas when it is manufactured, transported, or stored.

Any gas filtration installation needs to remove these contaminates, so that the gas is condensate, oil and particulate free, prior to the sterile gas filter. This then allows the filter to run at low differential pressure and its most efficient at removing microorganisms, bacteria, and viruses so that they cannot be transferred into the process or product that the gas contacts.

Understanding these issues helps ensure the correct filter for the application is chosen and sized correctly, and that once installed, runs without problem.
