Product details
Ⅰ. Product Overview
U&D fine bubble disc diffuser has the features of U&D fine bubble membrane dffusers. lts support is made of ABS or PP+ fiberglass materials. Its standard membrane is EPDM membrane with precise pores favorable for high oxygen transfer and utilization. In order to adapt to different requirements of sizes for aeration system, different slit lengths, distances and pore opening density are used to regulate the working pressure. According to customerneeds, silicone rubber membrane and polyurethane membrane are also supplied as substitutes.
