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.
