Product description
Application
Standard type of Alfa 16-100 fans are designed to force the movement of chemically inert medium within ventilation systems and technological lines on marine vessels, without any restrictions in the area of operation. The fans are intended for air exchange in cargo holds, engine room fans and closed compartments. The temperature of medium flowing through the fan should not exceed 318K (45°C) and the dust content should not exceed 0,3g/m3. Alfa type fans have a power consumption curve adapted to efficiency: the energy consumption decreases as the efficiency rises above the optimum efficiency point, so that the motor is protected against overload.
Design
Alfa type centrifugal fans are produced in 9 sizes: 16, 20, 25, 31,5, 40, 50, 63, 80 and 100. Each size can be made in 8 mounting positions: RD0, RD90, RD180, RD270, LG0, LG90, LG180 and LG 270. In standard execution, the impeller, the housing and the foot are made of black steel od standard quality.
Corrosion resistant and aluminium executions available on demand.
Alfa 16-100 fans are produced with direct drive (the impeller is mounted directly on the motor shaft) and are equipped with vibration dampers.
