Providing bottom-diffuses aeration in shallow ponds and lakes can provide a unique challenge to pond owners. Less water depth means smaller plate coverage which usually translates to bigger, more expensive, multi-plate systems. Airmax SW series Shallow Water Aeration Systems provide multiple plates to provide evenly distributed aeration in shallow water applications without forcing customers into large cost-prohibitive aeration units. Designed specifically for use in shallow water, SW series aeration systems aerate ponds up to ½ surface acre at 6' deep.

SilentAir Standard Composite Cabinet

Attractive composite cabinet houses and protects the SilentAir Compressor from outdoor elements. An integrated cooling system utilizes a UL-listed high-flow cooling fan and high-density air intake pre-filter to distribute air evenly throughout the cabinet keeping the interior components clean, cool and dry. An elevated base protects the aeration hardware and electrical components from flooding and rainwater accumulation while the removable top ensures quick and easy access for inspection and maintenance. Every SilentAir Standard Composite Cabinet in SW series comes complete with a pre-wired one-gang duplex electrical box and 6 foot power cord to provide power to the enclosed cooling fan and aeration compressor.

SilentAir Series Aeration Compressor

The heart and soul of each SW Aeration System, our powerful yet energy efficient SilentAir diaphragm compressors push oxygen through your pond while remaining whisper-quiet and costing as little as $3 a month in electricity running 24/7. Each SilentAir aeration compressor is fitted with an integrated air regulator to provide easy airflow-management and is mounted on vibration reducing rubber feet to ensure quiet operation.

ProAir-2 Diffuser Plates

Designed for maximum oxygen uptake, our ProAir-2 Diffuser Plates incorporate high-efficiency low-maintenance membrane sticks to release tiny oxygen bubbles into the water column. Membrane diffusers posses the synergy of air stones without the headaches of cracking and acid-washing. Our new non-stick Teflon coating prevents debris accumulation and performance reduction. A self-weighted black powder-coated steel base elevates the diffusers off of the pond bottom and out of muck and debris. Combined with a one-piece air distributer and one-way check valve the ProAir diffuser plates truly provide maximum output with virtually no maintenance.

EasySet Self-Weighted Airline

Designed to stay submerged underwater and out of sight, EasySet self-weighted airline is guaranteed not to float. A thick wall and lead-free construction make EasySet airline the perfect pond-safe choice. Resistant to rips and tears, EasySet airline is resilient against fishing hooks and foot traffic from swimmers, pets and wildlife.
