QSB0.75 – Submersible Jet Aerator 0.75 kW
High-efficiency gas-liquid mass transfer system designed for mid-to-deep aeration applications in wastewater treatment and aquaculture.
Product Overview
The Lanjiang QSB0.75 is a compact submersible jet aerator engineered for small-scale wastewater treatment, equalization tanks, and aquaculture aeration. This unit utilizes an advanced jet aspiration principle to deliver superior oxygenation without external air compression systems.
Technical Specifications
Power Rating:
0.75 kW
Current:
2.9 A
Air Flow:
10 m³/h
Max Operating Depth:
1.5 metres
Operating Principle
The pressurized water jet creates negative pressure in the diffuser throat, drawing in atmospheric air without requiring any external air compressor or blower. The air-water mixture discharges at high speed through the aerator outlet, creating wide and deep vortex mixing patterns that ensure effective oxygenation throughout the tank.
Key Features & Benefits
- Unidirectional flow generates strong circulation currents preventing sludge settling
- Maintains uniform dissolved oxygen levels throughout the tank
- Constant shaft power characteristic - motor load remains stable regardless of water level fluctuations
- Non-clogging impeller design ensures reliable operation in challenging wastewater conditions
- Ideal for tanks with varying water depths
- FQSB floating variant available with stainless steel pontoon for surface installation
