Introduction
We are a professional supplier of high-temperature centrifugal fans, which are industrial ventilation equipment designed for high-temperature working conditions. Their working principle is based on the centrifugal force generated by high-speed rotating impellers.
Features
High-temperature Resistance
The key components of high-temperature centrifugal fans are made of heat-resistant stainless steel or carbon steel structure, and the bearing area is equipped with a double-layer insulation layer, which can stably work at 100℃ to 1300℃.
Efficient Aerodynamic Performance
The fan adopts a backward-inclined impeller structure to effectively reduce airflow resistance and energy consumption, ensuring high-efficiency operation during high-temperature gas transportation, which is 20%~30% more efficient than traditional fans.
Stability
The fan volute and frame are made of high-strength steel plates, and the dynamic balance calibration reaches the G4.0 level. The vibration speed is controlled within 1.0mm/s, ensuring long-term stable operation, and the structure is not easy to deform.
Easy Maintenance
The key parts of the product, such as the bearing area, reserve sufficient operating space for easy disassembly and daily maintenance.
Applications
High-temperature centrifugal fans are widely used in industrial systems that require high-temperature gas transportation and hot air circulation, and are suitable for:
- Industrial furnaces/heat treatment furnaces: discharge high-temperature exhaust gas to ensure a stable temperature in the furnace.
- Boiler system: provides combustion air or induced draft exhaust.
- Metallurgy/chemical industry: ventilation and exhaust of high-temperature reaction equipment to improve equipment safety.
- Glass and ceramic kilns: exhaust smoke and dust, control temperature and atmosphere.
- Drying system: circulate hot air to improve drying efficiency.
Storage and Maintenance
- Cleaning inspection: Please clean the casing, impeller, and inlet and outlet before storage to ensure that there is no oil, dust, or dirt.
- Rust protection: Metal parts such as shafts and impellers should be coated with rust inhibitors or special grease.
- Packaging and transportation: It is recommended to wrap with foam cotton and place in a customized wooden box to prevent damage from collision.
- Environment selection: Store in a dry and ventilated place to avoid condensation and component corrosion caused by temperature differences.
- Periodic inspection: Check the packaging, rodent prevention, and whether the impeller can rotate flexibly every month.

FAQ
Q: Are you a manufacturer or a trader?
A: We are a manufacturer specializing in providing different types of customized fans/blowers for the market.
Q: What are your terms of payment?
A: TT 30% as advance payment and TT 70% paid before shipment.
Q: What information should I provide when inquiring?
A: Air volume, wind pressure, and whether there are any heat resistance requirements, explosion-proof requirements, anti-corrosion requirements, or any other requirements, etc.
Q: What is the working principle of a high-temperature centrifugal fan?
A: The high temperature centrifugal fan drives the impeller to rotate at high speed through the motor, so that the gas is thrown from the center of the impeller to the edge of the impeller under the action of centrifugal force, obtains kinetic energy and is discharged, and at the same time, the center of the impeller forms a negative pressure to inhale new gas.
Q: What high-temperature environments are suitable for a high-temperature centrifugal fan?
A: High-temperature centrifugal fans are suitable for high-temperature environments such as industrial kilns, drying equipment, smelting, etc.
Q: What are the key points for installing high high-temperature centrifugal fan?
A: When installing high high-temperature centrifugal fan, ensure that the foundation is firm and flat, and the connection between the fan and the pipeline is well sealed to avoid air leakage. The motor wiring is correct, and the overall levelness of the fan meets the requirements to ensure smooth operation.
Q: What should be paid attention to when starting the high-temperature centrifugal fan?
A: Before starting the high-temperature centrifugal fan, check whether the connection of each component is firm and whether the lubrication is good, close the outlet valve, and slowly open the valve after the motor starts smoothly to prevent excessive starting current.
Q: What is the function of the sealing device of the high-temperature centrifugal fan?
A: The sealing device of the high-temperature centrifugal fan can prevent the leakage of high-temperature gas, ensure the stability of the internal pressure of the fan, improve the transmission efficiency, and avoid the adverse effects of gas leakage on the surrounding environment and equipment.
Q: What preparations are needed to restart the high-temperature centrifugal fan after a long-term shutdown?
A: It is necessary to check whether the components of the high-temperature centrifugal fan are rusty or damaged, re-lubricate the bearings, test the insulation performance of the motor, clean the impeller and the debris in the pipeline, and put it into use after the no-load test run is normal.
Q: What are the functions of the control system of the high-temperature centrifugal fan?
A: The control system of the high temperature centrifugal fan has the functions of start and stop control, which can monitor the operating parameters of the fan, such as temperature, pressure, speed, etc., and can alarm and automatically shut down in case of abnormality, and can also realize remote control.
