Long Lifetime Steam Boiler Backward Centrifugal Ventilation Fan
Introduction
The Long Lifetime Steam Boiler Backward Centrifugal Ventilation Fan has moderate pressure and large flow, belongs to the low noise series fan and has stable performance.
It’s suitable for conveying normal temperature or high temperature non-flammable gas (normal air, high temperature gas, corrosive gas, dusty gas), and conveying granule/powder/chip/fiber material.
It’s a widely used medium-pressure heavy-duty centrifugal fan, which is commonly used in industrial systems such as boilers, dust collectors, desulfurization systems, cement, chemicals, metallurgy, electric power, and gas and material transportation. It can also be used for general ventilation.

Advantages and Features
1. Long Lifetime Steam Boiler Backward Centrifugal Ventilation Fans can output higher outlet pressure and provide more gas flow with lower noise. Ability to work stably at higher media temperatures.
2. Customized design according to customer's performance requirements, and optimized by CFD technology, the energy consumption is lower than similar models.
3. The airflow channel and the impeller have been optimized several times, which is more efficient and energy-saving than ordinary large-flow fans.
4. For the material of impeller and main shaft, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature resistant high-strength alloy steel for different working conditions temperature and working speed, so that the impeller and main shaft can still maintain a reliable strength at high temperature.
5. For dust-containing gas, we can meet various working conditions from a small amount of dust to a very large dust content. After special treatment, the surface hardness of the blade can reach HRC60~70, which can extend the life of the impeller by more than 3 times.
6. The Long Lifetime Steam Boiler Backward Centrifugal Ventilation Fan's impeller is subjected to high standard dynamic balance correction to ensure stable operation of the fan.
7. The Long Lifetime Steam Boiler Backward Centrifugal Ventilation fan system adopts a detachable design, which greatly reduces the transportation cost of customers.
8. Each part has an installation number and can be successfully assembled under the guidance of the installation manual.
9. Provide on-site installation guidance services.
