Next generation ventilation solution
Clima-Flow DM 36, DC 50, DM 50 and DC 57 is the ideal exhaust fan whenever high air flow 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 Italy’s R&D lab. The test chamber has been built according to ANSI/AMCA210-85 Figure 15 specifications. Construction details and air tightness have been verified by personnel of the BESS Lab at the Agricultural Engineering Department, Universityof Illinois – USA
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 and low energy consumption as well as low noise. The shutter is made of galvanised steel for all models, which is stronger than aluminum 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 hinders the shutter from being closed by air pressure, keeping the efficiency of the fan at a peak at all times by keeping the shutterfully 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.
