High temperature centrifugal fans series VB-H
GENERAL TECHNICAL DATA
High temperature duct fans are designed to transport relatively clean air up to 250 ° C. They are suitable for servicing various technological processes, dryers, ovens and others.
Depending on the type of part, the corrosion protection is galvanizing or phosphating and painting with temperature-resistant silicone paint. The fans are equipped with a radial impeller fixed to the axis of the 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 "F", level of protection IP54 - according DIN IEC 34, part 5, flange-mounted construction - according DIN IEC 34, part 7.
Kram reserves the right to make any dimensional design changes in accordance with their improvement program.
