Centrifugal Single Inlet Fans

MBA

APPLICATION
Fan designed for transporting non-aggressive and non-explosive gases
without contamination. Typical applications:
∙ pneumatic transport,
∙ blowing in drying systems (eg. graphic machines and plastics processing),
∙ air blowing systems in combustion / heat treatment systems (eg. melting furnaces).
CONSTRUCTION
∙ medium-pressure centrifugal fan with direct drive,
∙ riveted impeller from aluminium sheet with forward curved blades, 
dynamically balanced according to ISO 1940-1,
∙ aluminium cast housing,
∙ galvanized protective mesh at the inlet,
∙ model 600 is equipped with a motor support,
∙ fan painted grey RAL 7042,
∙ maximum temperature of the transported medium is 80ºC,
∙ ambient temperature range from -20º C to + 40ºC,
∙ figure LG270.
MOTOR 
∙ asynchronous, single-phase, 230V, 50Hz (power from 0.75 to 1.5kW),
∙ asynchronous, three-phase, 230 / 400V, 50Hz (power from 0.75 to 1.5kW),
∙ asynchronous, three-phase, 400 / 690V, 50Hz (with power 4.0kW and 11.0kW),
∙ efficiency class IE3 (power from 0.75 kW) or IE1 (0.75 kW, 230V),
∙ degree of protection IP55,
∙ insulation class F,
∙ three-phase motors are adapted for frequency converter,
SPECIAL EXECUTIONS
∙ optional configuration LG/RD,
∙ colour other than standard,
∙ impeller made of galvanized steel sheet,
∙ impeller made of stainless steel 1.4301,
∙ impeller made of acid-proof steel 1.4404,
∙ motor with voltage and frequency of power different than standard,
∙ for voltage regulation (single-phase motors),
∙ motor with other than standard degree of protection,
∙ motor equipped with sensors or additional cooling,
∙ sealing between the housing and the motor, 
∙ maximum temperature of the transported medium above 80ºC,
∙ ambient temperature range below -20ºC and above +40ºC
