Elizar Aquaculture has been established with a vision to produce best paddle wheel aerator for aquaculture farmers. From a years of experience we observed that farmers are facing many problems with the aerator i.e. it creates low Dissolve Oxygen (D.O.), Motor takes more AMPS, It splashes low water current, Impeller depth has not much deep because of shape and design of impeller, Rust in motor and gearbox, Gears got damage after 1 year. Due to these problems durability of aerator decreases by 2 years.
