Sterile Tank Vent Filters
 |
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 tank vents
To reduce batch contamination, spoilage, and product loss, effective sterile submicron filtration is a necessary part of your process. Especially important in the food, beverage, and pharmaceutical industries, sterile filtration protects your product from harmful submicron particle contamination and bacterial transfer or growth.
To maintain safe,balanced pressure during the filling or emptying of a storage vessel, tank vent or breather filters are essential to reduce the possibility of contaminating your product.
How MicroPure Tank Vent Filters do it better
System Security
- Self-sealing PTFE membranes with a 0.2 micron retention efficiency for air and gas.
- Each Filter Membrane works independently allowing for maximum filtering capability.
- A stainless steel tension rod and parts that provides continued support upstream and downstream of the filter membrane.
- The design of Micropure Segmented Filters has been subjected to extensive testing in
- Europe and the United States.
Application Versatility
- The required segmented element length and diameter are determined by your application giving each application an individualized fit.
- Unlike conventional cartridge filters, Micropure's Segmented filters can handle bi-directional flow.
- Filters allow higher flow rates than conventional filters while maintaining submicron bacterial efficiency.**
- High Temperature Tolerance
Unlimited Reusability
- Stainless Steel segmented discs, which will out last the conventional cartridge style filters.
- Since each membrane acts independently, Increasing flow rate or pressure can be achieved by simply adding more membranes/segmented element discs.
Economical
- You only Replace the media discs. The element stays in the filter for its entire life.
- Cost of Ownership is significantly less than competitors.
Convenience
- MicroPure filters can be steam sterilized "in-situ" or in place up to 150 times with no loss of filtering effectiveness as validated by an internationally recognized food laboratory.
- Micropure filters can Also be sterilized using autoclave, hydrogen peroxide, steam or a variety of sanitizing agents.*
- Membrane Replacement is Simple and Easy.
- Simple, on-site visual inspection of individual filter membrane
- Membranes are easily removable for laboratory analysis or culture.
- easily mounts to tanks and containers
- excellent breathing properties with weatherproof cover
MicroPure Segmented Tank Vent Filters feature a patented design that offers significant advantages over conventional filter cartridges.
Self-sealing PTFE membranes with a 0.2 micron retention efficiency for air and gas 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.
No other filter offers this combination of features:
Perforated Stainless Steel Modular Segments
- allows for bi-directional flow during sterile breathing on tanks and containers
- Clean-in-place with steam (150 times) or common sanitizing agent*
Durable Materials of Construction—Stainless Steel and PTFE
- broad range of chemical compatibility
- autoclavable, high temperature tolerance
- low extractable levels
Unique Flat, Double Layer Membrane Design
- low replacement cost compared to conventional cartridge
- long operational periods due to high throughput,initial pressure drop and high capcacity.
- Simple, on-site visual inspection or “plating” or individual filter membrane; easily removable for laboratory analysis or culture.
Simplicity of Design
- Easily mounted on tanks or containers
- excellent breathing properties with weatherproof cover
- capacity increased by adding segmented discs.
