The Vertex Air 1 Plus is an inexpensive solution for small, 1-2 acre ponds with irregular shapes and depths that impede normal diffuser circulation. This is a package price that includes 2-100 foot lengths of bottomline Tubing. The Air 1 Plus has the same powerful compressor system and cabinet as the standard Air 1 system, but includes a valve manifold and second CoActive AirStation for extra circulation. This additional AirStation can be placed in cove areas, finger canals, behind shallow sandbars, or anywhere in the water body where the pond’s shape or bottom contour will limit oxygen flow from a single diffuser. The Air 1 Plus utilizes Vertex’s MicronBubble technology allowing vital oxygen to be absorbed and poisonous gasses expelled. With no electricity in the water, Vertex’s aeration systems are safe for any type of water recreation. Our systems have an industry leading two-year warranty plus a five-year warranty against rust and corrosion on the cabinet, five-year warranty on the AirStations and a 15-year warranty on BottomLine supply tubing.
