Aeration Tube Diffusers

The aeration tube diffuser unit is a fine pore, flexible membrane diffuser capable of providing a high level of oxygen transfer efficiency with maximum mixing capability.

Standard configuration includes 3/4-inch stainless steel nipple installed. The stainless steel nipple can also be shipped loose, or a thru- mount connection can be provided for mounting units on square tubing.

T-Series threaded units are also available in saddle mount style configuration for special design applications.

Standard diffuser membranes are EPDM and PU, with Silicone and PTFE membranes available.

Multiple lengths and diameters available. Membranes held in place with 304 SS clamps. 316 SS clamps available. For special applications, nonmetallic clamps are also available.

For industrial and non-standard domestic applications, alternate membrane materials are including polyurethane, silicone, and other specialty polymers. These units may be operated over a wide range of airflows. The external triple-check valve system eliminates solids and minimizes entry of liquid into the diffuser unit and air supply piping under normal operating conditions. Standard aeration Tube diffusers with 3/4-inch NPT (male) stainless steel nipples are factory assembled and ready for installation.
