Sterile Air Filters
Segmented Design The Micropure Segmented design (shown above) offers significant advantages over conventional filter cartridges. Air or gas flows through the filter media into an adjacent segment. Filtered air or gas exits through openings at the center of the cartridge and out the sterile side of the housing.

Why you need sterile air filters

Sterile air filters reduce batch contamination, spoilage and product loss, effective sterile air filtration is a necessary part of your process. Especially important in the food, beverage, and pharmaceutical industries, sterile air filtration protects your product from harmful submicron particle contamination and bacterial transfer or growth.

It also helps protect production yield, especially in high-tech industries (electronics, plating, magnetic media, etc.) where submicron particle contamination can significantly reduce yields, resulting in product and dollar loss. The use of high efficiency submicron air filters have become a standard "current good manufacturing practice" allowing for more productive and economical processing.

MicroPure Segmented Sterile Air Filters feature a patented design that offers significant advantages over conventional filter cartridges. 

Self-sealing PTFE membranes with a 0.1 micron retention efficiency for air are sandwiched between perforated stainless steel segments within an stainless steel housing.  The independently functioning modular segments are clamped together by a stainless steel tension rod that provides continued support upstream and downstream of the filter membrane.  The required cartridge length and diameter are determined by your application.

Unlike conventional pleated cartridges that degrade with each sterilization, MicroPure filters can be steam sterilized in place up to 150 times with no loss of filtering effectiveness, as validated by an internationally recognized food laboratory. Other sterilization or cleaning methods commonly used are autoclave, hydrogen peroxide, steam, or a variety of sanitizing agents.*

When membrane replacement becomes necessary, the operational-and disposal-cost is considerably lower than for other filters.   With MicroPure filters, only the small membrane media are replaced-not the entire cartridge.

Due to the porosity of our double-layer PTFE membrane, MicroPure filters permit higher flow rates than conventional filters, while maintaining submicron, bacterial retention efficiency.**
The rugged, reliable design of MicroPure Segmented Filters has been subjected to extensive testing in Europe and the United States, with more than 5,000 systems installed in food-and beverage-processing applications.

The results are unquestionable: MicroPure Segmented Filters, designed for two-way flow, ensureconsistent, uncompromised security for any application.

Mini Filter Series If you have a small application or a small budget the Mini Filter Series might be the solution to your filtation needs. The same great quality and exceptional features at a lower cost to you.
