Tech Support Documents
Aerosart®
 

Aerosart® air filter is a high flow rate, low differential pressure, hydrophobic membrane filter. The unique single layer filter construction also reduces Blow-Down-time. Both the high flow rate and the short Blow-Down-time lowers the energy cost of air supply operations.

Product Information

Aerosart® high performance air filter cartridges can significantly reduce operating costs.

Applications

  • Large-scale fermentation inlet and exhaust gas filtration
  • Storage tank venting
  • Filling equipment venting
  • Any dry gas filtration

Microbiological Testing

They have been tested and passed:

  • Aerosol bacterial and viral challenge tests. Tests were conducted using Bacteriophage MS2 (NCIMB 10108) and bacillus subtils var. niger spores (NCTC 10073) at a challenge level of greater than 2.5 × 10⁷ under worst case conditions of greater than 90% relative humidity. No Bacteriophage MS2 or B. subtilis spores were detected on the downstream side of the Aerosart® filter cartridges.
  • Each membrane lot, liquid bacterial challenge test with the retention of ≥ 10⁷Brevundimonas diminuta/cm² according to current ASTM F-838 guidelines.
  • 100% integrity tested before to be released.

Performance

The unique single layer pleated filter construction of the highly hydrophobic PTFE membrane provides low differential pressures, excellent flow rates and the fastest blow down times of any gas service filter.

Long Service Life Time

The mechanical and thermal stresses experienced during steam in place sterilization pose the highest risk to any filter cartridge. In many cases, Aerosart® filter cartridges will be used for more the 120 steaming cycles. Tests have shown Aerosart® cartridges to pass integrity tests with greater than 150 steaming cycles.

Traceability

Clear labelling with lot number and individual unit number. All information lazer marked on each cartridge.
