Ventilation Fan

The main use of large circulation fans in livestock housing is to offer comfort cooling to the animals. For this very purpose, it is wise to use specifically designed circulation fans to provide the maximum cooling footprint at the dairy cow level.

EM50 is the ideal air recirculation fan whenever extra high air movement capacity is required. The unique propeller design is self-cleaning and allows the highest efficiency to be reached.
The square fan housing and air conveyor (venturi) are made of robust Galvanised sheet steel. The 6-blade propeller is statically and dynamically balanced for low noise and low vibration. The propeller is available in stainless steel, galvanised steel and pre-coated and galvanised steel.


The propeller is attached to a large v-belt pulley embedded in a double ball bearing protected against water. The belt transmission ensures low propeller rpm, which ensures high efficiency, low energy consumption.
