They have high efficiency and reduced noise level, the fans of this series are largely used, inventilation, conditioning, drying, cooling, mechnical draft, and toxic gas elimination plants. The temperature of the fluid transported must not exceed 80°C without cooling fan and 150° C with cooling fan. For higher temperatures it is necessary to modify the construction of the fan.
