PRODUCT DESCRIPTION

This is without float or bottom screen. The bottom screen is primarily purchased to protect swimmers from props. But you are not supposed to have swimmers in pond. The float is not needed if you have a mount already.

Kasco Aerators, or High Oxygen Transfer Units, are designed to withstand the rigors of commercial aqua culture operations. With more vertical pump type aerators in use in North America than any other manufacturer, Kasco Aerators have been field tested and proven superior. Aerators are used when a decorative fountain pattern is neither necessary or desired. Kasco Aerators agitate high volumes of water at the surface to maximize exposure of water to the air for gas exchange. Kasco Aerators are in use around the world in commercial aquaculture applications to farm ponds; from municipal waste water plants to your back yard, Kasco Aerators are designed to perform under a variety of conditions to ensure quality to you. Bottom Screen not included in price. Auburn University has performed tests on Kasco Aerators and has found that Kasco's Aerators SAE (Standard Aeration Efficiency) for all models is at least 3.0 lbs. of oxygen per horsepower per hour of operation.
