The DA-20 Display Aerator combines pond aeration with a decorative trumpet-shaped water display for medium residential ponds. It circulates up to 500 gallons of water per minute while adding oxygen to the water.
The 1 hp configuration produces an approximately 7-foot-high by 25-foot-wide spray pattern. The added oxygen helps control algae growth and insects while supporting a healthy environment for fish and other pond wildlife.
The unit uses a stainless-steel, oil-free submersible motor designed for continuous operation in fresh water and salt water. It can remain installed during winter after the power is turned off and can be restarted after the pond thaws.
