  • Roots blower AAT-50SD (1.1kW - 1.5HP, 220V/380V, 3 phase, 50Hz) in a Nursery pond.

  • Roots blower AAT-50S (2.2kW - 3HP, 220V, 1 phase, 50Hz) in a Nursery pond (2000 m2).


Simple, high capacity

The blower impeller adopts the original curve track and the optimized design to improve the full-adiabatic efficiency as well as the volumetric efficiency, which makes the capacity and pressure superior. The screen lines adopt the helical construction which used the method of casing at the suction and discharge sides to be cut to a helical shape.

AAT-50 blower often used to increase dissolved oxygen in the water for shrimp pond

Nursery ponds

Post-larvae resistance in stocking period is very low until day 25. For preventing and control diseases on shrimp as early mortality syndrome (EMS), acute hepato-pancreatic necrosis syndrome (AHPNS), white spot disease... New proactive method is used nursery ponds before moving shrimp grow-out ponds. AAT-50 blowers are the best choice to enhance dissolved oxygen nursery ponds.

Enhanced dissolved oxygen to the tilapia farms

Low dissolved oxygen can be caused by many factors. The most common is overenrichment (excessive feeding or inflow of nutrients) of ponds, which causes heavy phytoplankton blooms resulting in high respiration or consumption of oxygen. Phytoplankton can die off quickly causing a rapid decomposition of algae by increased bacteria concentrations that consume more oxygen. Hot weather naturally will result in lower oxygen concentrations because warmer water holds less oxygen. A turnover can occur if the cooler and more dense deeper water of ponds (which often also have lower oxygen concentrations) is suddenly mixed to the surface due to a heavy rain or strong winds.
