High Temperature Circulation Fan for Coating, Galvanizing and Drying Lines
A high temperature circulation fan is used to move hot air inside coating lines, galvanizing lines, drying ovens, curing ovens, and other industrial heating systems. Compared with a general exhaust fan, this type of fan must handle temperature, thermal expansion, bearing protection, insulation, vibration, and long-term continuous operation.
This is a strong product direction for Zhichengfans because it shows real manufacturing capability: welded housing, reinforced impeller, bearing seat design, insulation structure, belt or coupling drive, and customized inlet/outlet direction.
Typical Applications
- Color coating production lines
- Galvanizing line hot air circulation
- Drying oven and curing oven systems
- Food, material, and chemical drying systems
- Building material drying and heating systems
- Furnace hot air recirculation
Important Design Points
High temperature circulation fans should be designed according to actual working temperature and installation layout. The following points are especially important:
- Impeller material and strength at operating temperature
- Thermal expansion allowance for shaft and housing
- Double insulation or external insulation structure
- Bearing protection, cooling, and distance from hot air zone
- Belt drive or coupling drive arrangement
- Dynamic balancing and vibration control
- Maintenance access for bearings, belts, and impeller inspection
Selection Data Required
- Airflow and static pressure
- Working temperature and maximum temperature
- Gas medium and dust condition
- Continuous or intermittent operation
- Installation position and inlet/outlet direction
- Material requirement, such as carbon steel or stainless steel
- Motor position, voltage, frequency, and protection grade
Why This Fan Is Not a Standard Small Fan
Hot air circulation fans for production lines often work inside a complete process system. If the fan is selected only by airflow and pressure, problems can occur later, such as bearing overheating, impeller deformation, vibration, insulation failure, or insufficient hot air circulation. The fan should be matched with the process temperature, oven structure, duct layout, and maintenance plan.
Zhichengfans Custom Options
Zhichengfans can customize high temperature circulation fans with double insulation housing, stainless steel impeller, reinforced shaft, belt drive, coupling drive, special inlet and outlet direction, and different motor arrangements according to the production line layout.

FAQ
Can the fan use stainless steel?
Yes. Stainless steel can be selected when temperature, corrosion, or process requirements need it.
Is double insulation necessary?
It depends on temperature, installation position, operator safety, heat loss requirements, and bearing protection needs.
What should I send for a quotation?
Please send airflow, pressure, temperature, gas medium, installation layout, inlet/outlet direction, voltage, frequency, and material requirements.
