Application

Medium-pressure, radial directly-driven fans. The rotor is provided with backward-tilted blades, riveted, made of aluminum sheet, and dynamically balanced according to ISO 1940. As a standard, the inlet of the fan is provided with a steel casing. The fans are designed for transporting non-aggressive and non-explosive, dust-free gases.

On request, the rotors can be welded of steel or made of acid-resistant steel sheet. As a standard, the MBA fans are manufactured in LG270 configuration; any other LG configurations are available. On request, the fans may be supplied in RD configuration. On request, the device could be supplied in any color from the RAL palette (RAL 7042 - grey is the standard color).

Construction

Asynchronous, three-phase 230/400V or 400V, 50Hz, or single-phase 230V, 50Hz, with a capacitor. The motors are manufactured in accordance with IEC 60072 and IEC 60034 standards, and have been awarded with a CE mark. Insulation class F, degree of protection IP55.


On request, we can deliver motors driven by another voltage or frequency, adapted for voltage control or for a frequency converter, provided with an independent cooling system and/or with sensors (either bimetallic or posistor).

Electric motor

Pneumatic transport systems (e.g., PET processing), air supply in various drying systems (e.g., print shops and plastic processing), air blast systems in combustion/thermal processing systems (e.g. melting furnaces), etc
