The ProAir™-4 Weighted Diffuser is for use with the Airmax® Shallow Water Series™ Aeration Systems. The innovative sled design keeps the diffuser submerged while maintaining an upright position. The included check valve prevents back pressure on the compressor. Winterization Caps are recommended if you shut down your aeration system during the winter, as they prevent debris from entering the airline.
