Media Chemical Compatibility

The chemical composition and temperature of the process fluid must be considered in order to ensure the integrity of the filter media construction for the specified application.  Certain chemicals and temperature combinations can cause degradation of the filtration media resulting in failure of the media and downstream contamination in the process.

The attached chart provides a general guide for temperature and chemical compatibilities of the filter media Flow Tech offers.

Contact your Flow Tech Account Manager for further information and guidance on filter media selection.
