Double Inlet High Temperature Circulation Fan for Industrial Drying Ovens
A double inlet high temperature circulation fan is used when an industrial drying oven or curing oven needs large hot air circulation with stable airflow distribution. Compared with a single inlet fan, a double inlet design can support higher airflow in a compact arrangement when the oven layout allows air to enter from both sides.
This product direction is useful for Zhichengfans because it highlights practical manufacturing capability: reinforced housing, high-temperature impeller design, shaft and bearing protection, insulation, dynamic balancing, and customized installation dimensions.
Typical Applications
- Industrial drying ovens
- Paint curing ovens
- Coating line hot air circulation

FAQ
When should a double inlet fan be selected?
It should be considered when the system needs large circulation airflow and the oven structure can provide balanced inlet space on both sides.
Does high temperature require special bearings?
Often yes. Bearing position, cooling, lubrication, and heat isolation should be checked according to actual temperature.
What information is needed for quotation?
Please send airflow, pressure, temperature, oven layout, inlet/outlet direction, material requirement, voltage, and frequency.
