How it works ↓
What is a sterile filter?
A filter that retains micro-organisms at the point of use, in a stainless steel housing, with a steam-sterilisable cartridge. It comes last, after drying and filtration: it replaces none of the earlier stages.
Made for
- Pharmaceuticals, cosmetics
- Food, bottling, brewing, fermentation
- Any air that touches a product people consume
Not made for
- Retaining oil vapoursActivated carbon tower

The sterile filter holds back micro-organisms at the point of use, with a steam-sterilisable cartridge: food, pharma, brewing, any air that touches a consumed product. From 1.5 to 30 m³/min.
It comes last in the chain, after drying and activated-carbon filtration: it replaces none of the previous stages.
A sterile filter is the last barrier between the network and the product. It does not hold back dust: it holds back the micro-organisms that fine filtration lets through, with a bacterial retention greater than 99.99998%.
The cartridge is pleated PTFE, steam-sterilisable in place at 127 °C: it is sterilised without being removed, as often as the process requires. The housing is 304 or 316L stainless steel, mirror-polished to 0.4 µm so that no roughness can hold deposits.
It is fitted at the end of the chain, after the dryer and fine filtration. The air reaching it must already be dry and free of oil: a sterile cartridge placed too early loads up, and its service life collapses without adding anything.
Pharmacy, cosmetics, food processing, bottling, fermentation: wherever air touches the product, its container or a clean surface. Nine sizes, from 1.5 to 30 m³/min, 16 bar.
Retention > 99.99998%
Bacterial retention of the pleated PTFE cartridge, the level expected for air in direct contact with the product.
Sterilisable in place
Steam at 127 °C without removing the cartridge: sterilisation follows the rhythm of the process, not that of maintenance.
0.4 µm polished stainless steel
Mirror-polished 304 or 316L housing: no roughness where a deposit could settle, easier cleaning and inspection.
Always last
After the dryer and fine filtration. Placed earlier, it loads up with water and oil and adds nothing more.

Refrigerant dryer vs adsorption dryer: when should you switch to adsorption?
A refrigerant dryer covers most industrial applications with a +3 °C pressure dew point. Adsorption goes down to −40 or −70 °C but consumes compressed air. When should you switch?
