Housing The fan's robust construction is ensured by a combination of a steel frame and an aluminium casing, making the fans suitable for the most demanding weather conditions. The combination of casing and motor construction minimises maintenance requirements and enables long continuous operation. Impeller The noise-optimised impeller together with efficient motors is designed to deliver high performance with minimal energy consumption and maximum efficiency. Motor Fans up to size 311 are equipped with motors with built-in thermal contacts with manual restart. Fan speed can be controlled using a frequency converter with sinus filter, star/delta switch, thyristor or 5-speed transformer. Installation DVS/DHS fans can be installed in a prepared supporting structure or in a roof mounting frame supplied as an accessory. The fan can be installed with a maximum deviation of 15° from the horizontal position. - Additional Information
