HTFC-IV series fans adopt box design, and the impeller is mainly composed of twisted blades and circular-arc back disk in the matching space of streamlined inlet. Gas is sucked into the impeller through streamlined inlet and directly pressurized, thus reducing the efficiency loss caused by turbulence, thus having better aerodynamic performance. At the same time, the structure is more compact, saving installation space, making it the first choice for box fans with high cost performance.

High-streneth frame structure, light weight, good sealing, and better appearance. At the same time, sound attenuation measures can be configured according to reguirements. Direct drive has higher transmission efficiency, no wearing parts, low maintenance rate and more compact structure.

A variety of different air outlet directions can meet the design requirements of various pipe networks, making site construction more simple and flexible. The balance grade of impeller is as high as G2.5, which is much higher than that of G6.3, which greatly improves the stability of impeller operation.

3C certified product, which can run normally at 280℃ for 60min.
