EMS50 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 a strong galvanised sheet-steel. The 6-blade propeller is statically and dynamic balanced for low noise and low vibration. The propeller is available in stainless steel, galvanised steel and pre-coated and galvanised steel. To improve aerodynamic efficiency, the fan has been developed in Munters R&D lab. The test chamber has been built according to ANSI/AMCA 210-85 Figure 15 specifications. Construction details and airtightness have been verified by personnel of the BESS Lab at the Agricultural Engineering Department, University of Illinois – USA.
