Kasco pond aerators (also called high oxygen transfer units) are designed to withstand the rigors of commercial aquaculture operations, industrial applications, and municipal waste water plants.

With more vertical-pump-type aerators in use in North America than any other manufacturer, Kasco is the clear market leader in products proven to deliver outstanding performance and reliability. Kasco pond aerators dramatically agitate high volumes of water at the surface to maximize exposure of water to the air for valuable gas exchange, greatly improving your pond or lake aeration. Kasco's surface aertaors are designed to deliver up to 3.0 lbs of oxygen per HP per hour. Kasco's 5.1AF surface aerators are 5HP, single phase, low voltage (208/240V) units designed for optimal efficiency (18 amps). 5.1AF units require a minimum water depth of only 26". 

The 5.1A package includes: 

• 5HP, single phase aerator unit
• Power cord (available lengths: 100',150',200',250',300', or 400')
• Float and hardware

Optional bottom screens and hardware, light kits, and C-230 control panels are also available!
