The materials used to manufacture Excel® Cartridges, Housings and Accessories are carefully chosen for their resistance to a wide range of chemical solutions and can be modified to further extend this range.   However, due to the number and combinations of chemicals available, knowledge about compatibility between the fluid to be filtered and the filtration system employed is essential.  Chemical compatibility is affected by many variables including time, temperature, pressure and concentration. Please contact us regarding chemical compatibility for your applications.
