Below in the table you can find an indicative filter distribution for different filtration purposes.

For more information about filter applications, please contact us.

In case of interest we can send you Validation lists for selected filters.

If you are not sure about the appropriate choice of filter, do not hesitate to contact us. We also offer you the option of purchasing test LVD disc for testing the filterability of your products.

TURBOSEP

•  Specifically designed for the removal of foam aggregate and aerosol from fermenter off-gas, TURBOSEP improves the overall efficiency of the fermentation process and facilitates the effective operation of final sterilizing grade filters.
• This highly efficient mechanical separator has no moving parts and very low pressure drop. Foam, aerosol and entrained liquid removal from the off-gas are returned to the fermenter housing thereby minimizing product loss.
