Subsurface aerators are a great solution for many of our customers, especially since Deep Aire subsurface aerators do not require electricity to be in a pond. We broke down all you need to know about one of our best pond aerators to help your pond stay clean and healthy.Subsurface aerators, or diffused aeration systems, are designed as an alternative source of aeration, taking oxygen to a pond’s lowest depth along the bottom. Diffused air systems utilize an air compressor, located on the shore, that delivers oxygen through a hose to a special diffuser lying on the pond bottom.A submersible aerator or large pond aerator like this one keeps the pond or lake clean and healthy without a large spray pattern. A Deep Air subsurface aeration system is perfect if you’re looking for something that requires no above surface water spray, surface obstructions, or installations that prohibit the use of electricity in the water.PERFECT FORPonds on golf coursesPonds in public placesAny body of water that needs to regulate water aerationAnyone wanting an aerator but not a big spray patternBody of water installations that prohibit the use of electricity in the waterRecreational bodies of water like lakes or swimming areas.PERKSNo electricity required at the water’s edge. Your compressor needs electricity, but the compressor can be located wherever you desire.No floating object on the water surface enabling you to go boating or fishingLower maintenance and service costs due to no moving parts in the waterSafer swimming. These systems do not require electricity to be in the pond.Eliminates thermal stratification, making it ideal for deep-water applicationsOne compressor aerates one long, narrow pond, or two small pondsImproves water quality and clarityLow operating cost.HOW IT WORKSThese Units are a subsurface aeration system with a piston type air compressor, air hose, and an air diffuser. Designed to improve oxygen levels and destratification in deep bodies of water.The shore mounted rocking piston compressor produces compressed air through a air tube to a membrane diffuser located on the bottom of the pond. The compressed air is released into the water through the membrane diffuser releasing thousands of fine bubbles, which rise to the surface. As the bubbles of air rise, oxygen is transferred into the water. Simultaneously, as the bubbles rise, water is pulled upward, creating a flow of water from the bottom of the pond to the surface.THINGS TO CONSIDERWhen selecting a subsurface aeration system, consider the shape, surface area, and depth of the pond. The amount of surface area the diffused system will effectively cover is dependent on the depth of the shape of the pond. The area of coverage increases the deeper the diffuser is located in the water.The shape of a pond also affects the number of diffusers needed. An irregular shaped pond, (i.e. kidney-shaped), rectangular, or one with an island or peninsula, will require multiple diffusers to adequately disperse the oxygen.
