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 aluminum 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 aluminum alloy,
• motor support in the 600 model,
• galvanized mesh on inlet in models 200 and 600
• standard color of the fan is gray RAL 7042,
• maximum temperature of the transported medium is 80^oC,
• ambient temperature range from -20^oC to +40^oC,
• figure LG270 (model 350 in the figure RD270).
