Vertex XL4 AirStation Aeration Diffusers (Best Depth: 16'+) for aeration systems. Each CoActive AirStation consists of four self-cleaning, 9" diameter flexible membrane diffusers of EPDM compound with 100% rebound memory, each producing millions of fine 500 to 3000-micron bubbles. Each diffuser station is equipped with a vacuum-formed HDPE base; sonic spot-welded to provide unit integrity. The base unit has a hollow chamber design for the addition of gravel ballast and a lipped design to prevent settling into soft bottom sediments.
