High temperature duct series KVB-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.
High temperature duct fans are made of sheet steel. The anti-corrosion protection is by phosphating and painting with temperature-resistant silicone paint and 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.
The various types and type-dimensions of duct-fans bear the following marking: Class, Nominal diameter off impeller, Fitting dimensions, Art and version of impeller, Current type (Tree phase or Single phase), Number of poles and Version.
