Centrifugal Fans range VCD
GENERAL TECHNICAL DATA
GENERAL TECHNICAL DATA
The centrifugal fans are made of powder painted (RAL 6019), sheet steel and are completed with radial impeller fixed on electric motor Тhe impeller and the motor are statically and dynamically balanced.and this ensure a long exploitation term and low level of vibrations..
The normal production is designed for 220/380 V ± 5% and frequency 50 Hz, class "B", level of protection IP44 or IP54 - according DIN IEC 34, part 5, flange-mounted construction - according DIN IEC 34, part 7.
Standard with fan inlet free of flange and by request with flange.
Optional: flexible connectors, air filters, heaters, attenuators etc.
Kram reserves the right to make any dimensional design changes in accordance with their improvement program.
