Sanco Air Blower Series BRF / BRH are rotary vane systems. Small and compact Used for aeration in fish ponds in shelters. Good quality, durable products

Rotary Air Blower Product Description The Rotary Air Blower utilizes an involute profile integral shaft ductile iron impeller design. The head plate, gear cover, end caps and rigid one-piece housing are made of gray cast iron. Carburized and ground alloy steel timing gear tapers are mounted on the shaft and secured with locknuts. Cylindrical roller bearings are used on the drive end and ball bearings on the gear end. The characteristics and advantages of rotary blowers 1. Small size, large air volume, low noise, and low energy consumption (the rotary blower adopts the principle of operating compressed air, although small in size, it has high air volume, energy saving, and operates quietly) 2. The operation is smooth and the installation is very convenient (for small models, as long as they are placed properly, the vibration is minimal and there is no need to install anti vibration devices, making the installation very convenient). 3. Resistance to load changes and stable air volume (for example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume also changes very little with the pressure change). 4. Equipped with an air chamber for smooth air dissipation (all models are equipped with an air chamber to prevent air pulsation and ensure smooth air dissipation). 5. The material is excellent, the structure is clever, and the performance is excellent (all blowers are made of high-quality materials, the structure is exquisite, sturdy and durable, and the performance is excellent, with few faults occurring during long-term use). 6. Simple maintenance, few malfunctions, and long service life (low speed, low wear, and long service life).

1. Low noise, due to the helical suction and discharge, the blower air flow in and out according to the direction of spiral line, all these prevent the pulse noise and vibration. What's more, by using the Impedance complex muffler, the noise of our blowers are further reduced. 2. High volume and anti-heat efficiency, so it is energy-saving. The blower rotor adopted the advanced Composite curve, the meshing is more reasonable, and further increases the volume efficiency. 3. Stable performance. The blower rotor, casing, wall panels, shaft and other key components are all produced by the advanced digital-control processing equipment thus make the interchangeability of parts and components increased. 4. Low vibration. Although the rotor has been processed precisely, and are all in balancing condition, we still adopted the high precision balancing equipment and grinding machine to make it more balance. Therefore, the blowers are almost no vibration. 5. With high precise and hardness Synchronization gear, we not only extension blowers life, but also reduce its noise.
