SSI Fine Bubble Disc Diffuser

We manufacture our disc diffusers with compression molded membranes.Standard materials are EPDM and fluoroelastomer layered EPDM.There is an art to using just the right amount of plasticizer in an EPDM membrane. Use too much, or the wrong type, and emulsifying fats can leech plasticizer and cause shrinkage and increase hardness. Use too little, and the rubber loses its memory, bubble size increases, and the membrane is at risk for flexure failure. SSI has had a great deal ofexperience experimenting with different types and amounts of plasticizer, as well as other components of formulated EPDM rubber, such as fillers and curatives, and we put this experience to work.SSI uses a specially shaped tool to punch holes in the diaphragm from the inside out.This minimises the size of the holes in the diaphragm surface. Through specialised  synthesis and surface treatment techniques, we are able to machine smooth holes in hydrophilic surfaces, checking the uniformity of the perforation depth of each diaphragm to ensure uniform air release, and quickly release small air bubbles as small as 1-2mm in diameter.

Single mold technology to reduce costs.
