Em30-exhaust Fan 30inch Dia With Shutter

FOLLOWING ARE THE FEATURES OF EM30-EXHAUST FAN 30INCH DIA WITH SHUTTERl
EM30 is the ideal exhaust fan whenever high airflow 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 euroemmeA-s R&D lab. The test chamber has been built according to ANSI/AMCA210-85 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 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 and low energy consumption as well as low noise. 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.
