Product Description
DUBHE 215/270/350 (7/9/12") Disc Diffuser systems combine engineering excellence, superior component quality,and a technically advanced product concept. Unibody plastic construction means the diffuser is a single piece. Because of unique developments related to product design and production automation you can purchase this high quality diffuser for an economical price. You get the same high quality membrane that is known for its durability, The plastic material is made from the highest-quality, sorted recycled polypropylene resin. When the time comes to replace the diffuser, simply unscrew the old one and screw a new one in. Replacement is clean and quick, and because it is made of recycled plastic, it is also environmentally friendly. Oxygen transfer and head loss performance are equal to the current product line, because we have not changed the membrane or the orifice diameter of diffuser
