EC50 cone fan, a 50" fan equipped with cone discharge, is the ideal fan for high air-flow capacity at high static pressures and low energy consumption. The unique propeller design is self-cleaning and allows the highest efficiency to be reached, while the discharge cone boosts the airflow dramatically. The square fan housing, cone discharge and air conveyor (venturi) are made of a strong galvanised sheet-steel. The 3-blade propeller is statically and dynamic balanced for low noise and low vibration. The propeller is available in stainless steel, galvanised steel and precoated, galvanised steel. To improve aerodynamic efficiency and reduce pressure losses the cone fan design 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. Propeller, cone discharge and shutter The propeller is attached to a large v-belt pulley in which is embedded a double ball bearing protected against water. The belt transmission ensures low propeller rpm, which ensures high efficiency, low energy consumption as well as low noise. The cone-discharge is made in 4 separate pieces to assist with knock-down transportation, and all in galvanised steel. The shutter is made of galvanised steel for all models, which is stronger than aluminium and plastic. The fan shutter is tightly closed when the fan is not working preventing any air leakage through the fan. The patented centrifugal system prohibits the shutter from being closed by air pressure, keeping the efficiency of the fan at a peak at all times by keeping the

shutter fully and firmly opened. The shutter does not have to be cleaned regularly as dust does not affect its opening and closing movement. All the plastic parts are made of acetalic plastic with UV protection.
