∙ the rotor is made of steel sheet with blades inclined backwards,
painted with primer paint, dynamically balanced according
to ISO 1940-1,
∙ rectangular housing made of steel sheet (models 250 to 400),
spiral housing made of steel sheet (425 models and larger),
∙ fan painted blue RAL 5010 (corrosivity category C3),
∙ maximum temperature of the transported medium is 80oC,
∙ ambient temperature of the motor from -20oC to +40oC,
∙ figure LG90 (models 250 to 355), figure LG270 (models 400 and larger).
MOTOR
∙ asynchronous, three-phase 230V/400V 50Hz or 400/690V 50Hz,
∙ degree of protection IP55,
∙ insulation class F,
∙ three-phase motors are adapted for frequency converter.
SPECIAL EXECUTIONS
