Low-pressure centrifugal fan. High efficiency and low-noise reverse-blade impeller. Directly coupled motor. 

Air flow : 22-1,600 m3/min

Pressure : 10-390 mmwg

Use: for the removal of clean or slightly dusty air. 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.
