Application

MBB Ventilators:

Construction

Medium-pressure, radial directly-driven ventilators. The MBB ventilators – provided with backward-tilted, profiled  blades. Both types of rotors are made of welded steel or aluminum sheet and are dynamically balanced according to ISO 1940. Housing is made of welded steel sheet.

On request, housing and rotors can be made of acid resistant or galvanized steel sheet. As a standard, the ventilators are manufactured in the LG270 configuration (the MBB-2-560/180-3000 and MBB-2-560/180-3700 fans are routinely available in the RD270 configuration). Other configurations of the ventilators are available on request. On request, we can supply the equipment in any color from the RAL palette (RAL 5010 - blue is the standard color).

Electric motor

Asynchronous, three-phase 230/400V, 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 IP 55.

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