Product Description

Product Overview
fine bubble disc diffuser has the features of U&D fine bubble membrane diffusers. Its 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 customer
needs, silicone rubber membrane and polyurethane membrane are also supplied as substitutes.
