Replacement Membranes
Suprafilt is the leading aftermarket supplier of replacement membranes for all brands and types of diffuser. Membranes are manufactured using the same high quality materials we use for our own products. For high resistance to fouling and for longer term efficiency we offer PTFE coated EPDM as an option. We also manufacture backer plates which enables us to transform old inefficient ceramic domes into efficient and effective membranes. We recommend that membranes are replaced every 5 to 8 years as typically, over this period, the efficiency reduces due to deterioration of the rubber and fouling of the membrane surface.
