Centrifugal Single Inlet Fans

MPA 

APPLICATION
Fan dedicated to polluted air exhaust systems and pneumatic transport.
Examples of use:
∙ local exhaust systems, dehumidifiers, drying systems,
∙ transport of shavings, sawdust, granulates,
∙ combustion gases exhaustion systems.
CONSTRUCTION
∙ medium-pressure, directly driven centrifugal fans, 
∙ the impeller is made of aluminium alloy, provided with straight blades 
is dynamically balanced according to ISO 1940-1 (in models to 290, in 
models from 350 and 600 the impeller is welded of steel sheet),
∙ the housing is cast in aluminium alloy,
∙ motor support in the 600 model, 
∙ galvanized mesh on inlet in models 200 and 600
∙ standard colour of the fan is gray RAL 7042,
∙ maximum temperature of the transported medium is 80ºC,
∙ ambient temperature range from -20ºC to +40ºC,
∙ figure LG270 (model 350 in the figure RD270).
