Our paddlewheel aerators are greatly improved and produced according to the newest international technologies. Adopting whole plastic floats, these aerators have stainless steel transmission shafts and frames.In April 2000, these products were examined by the China Fishery Machinery Instruments Equality Supervision Center. All 9 models were evaluated as reaching the SC/T6017-1999 standard.With oxygen transfer rates of 2.59kg (O2)/h, 36.3% higher than the standard, power efficiency is 1.71kg (O2)/kWh, 36.8% higher than the standard.Features:1) Actual-bevel gears are used instead of worm gears, thereby economizing on energy with high efficiency, and saving over 20% electric energy over traditional models2) The actual-bevel gear is made of chromium-manganese-titanium with carbon-nitride surface treatment. This ensures long usage life spans and high rigidity3) A mechanical seal is available to prevent oil leakage4) Inside protectors are available to avoid the motor being accidentally burnt out5) PE floats, nylon impellers, and stainless steel shafts and frames are available6) adjustable shaft support, plastic palte
