Introduction Of Centrifugal Fan
The 4-09 series large-flow centrifugal fan is the earliest used fan
in China, and it is also the most commonly used fan. No viscous
substances are allowed inside the gas, and the dust and hard
particles contained in the gas are larger than 150 mg/m3, and the
gas temperature does not exceed 80°C.

Application
1. Install centrifugal fans in mines and tunnels to re-enter fresh
air and exhaust dirty air to ensure air circulation in the mines
and tunnels.Centrifugal fans can help dust discharge, ensure air
transparency in mines and tunnels, and ensure the health of workers
in mines and tunnels.
2. A centrifugal fan is installed in the cooling tower, which not
only plays the role of ventilation and ensures the normal operation
of the cooling tower, but also plays a positive role in improving
the cooling effect of the cooling tower by the large flow wind
generated by the centrifugal fan.
3. Main ventilator in coal mine is an important equipment to ensure
normal ventilation in underground mine, which not only affects the
production capacity of coal mine, but also is very important to the
safety of mining industry.
Product Advantages
1. When the pressure requirement is met, a large gas flow can be
output, and the noise is very low.
2. The fan speed can be flexibly set by matching different
diameters of belt pulley to make the fan run at the highest
efficiency point and reduce energy waste.
3. Motor sliding guides are provided for easy tensioning of the
belt to reduce energy loss due to belt slack.
4. When the airflow resistance is increased, the motor load will be
automatically reduced and the motor will not be burnt.
FAQ
1. What parameters need to be provided when you design the Heat
Dissipation Power Plant Blower Fan?
Answers: Air flow, total pressure or static pressure, inlet
temperature, local voltage and frequency, Altitude etc.
If there is flammable and explosive gas, or big dust loading in the
medium, please also inform the designer.
2. How about your company’s pre-sales service and after-sales
service?
Answers: Before our cooperation, we have the professional technical
team to help you make the technical solution according to your
working condition, to make sure the centrifugal fan efficiency
operation.
