Quad Membrane [CM-4] Self Sinking airBASE Diffuser Assembly

The airBASE™ complete self sinking diffuser assemblies are by far the best built units available in the industry. And we just don't say that. We actually purchased diffusers from many of our competitors and did our own testing. We found our airBASE™ diffuser assemblies to made from far superior HDPE materials and much thicker thermoplastic components. The performance of the units in operation was also far superior to many of the competitors diffusers. And our diffuser membranes are a fine bubble type making them much more effective over stone type diffusers. We believe this is just another example of our company demanding the best components in the industry. At AerationSupply.com we're not about offering the most products, we're all about offering THE BEST!
