gas circulation fan

A gas circulation fan is designed to recirculate process gases or clean air within closed-loop systems such as dryers, reactors, and heat exchangers. By maintaining a consistent flow, it ensures uniform temperature distribution and efficient heat transfer.

Featuring backward-curved impellers and corrosion-resistant alloys, these fans handle temperatures up to 200 °C and deliver flows of 5,000–80,000 CFM at static pressures up to 4 kPa. Precision balancing reduces vibration and noise.

Integration with variable frequency drives (VFDs) provides flow control based on temperature or pressure feedback, optimizing energy usage and process stability.

Maintenance is simplified via split-casing access, sealed-for-life bearings, and external lubrication points. Gas circulation fans are essential for chemical, food processing, and pharmaceutical industries requiring closed-loop gas management.
