Description

Properties flow rates up to 15,000 m³/h size: 250 - 630 mm (impeller diameter) asynchronous external rotor motor backward curved impellers terminal box design ; alternatively, lateral or axial cable outlet compact, space-saving design Properties Free running impellers ; Type: DKHR The fans are designed mainly for device installation and are preferably used in air-conditioners, hygiene equipment, clean room filter units and HVAC systems. During the development of the backward-curved impeller for use without a spiral casing, special emphasis was placed on optimising efficiency over a wide characteristic curve with high power density, whilst having as optimal a noise level as possible. The fans are designed to convey air and other non-aggressive gases or vapours. As drive motors, asynchronous external rotor motors from our own production are used. In addition to the modular design (DKHM), these fans are also available as a motorised impeller (DKHR). Impellers The impellers with 8 backward-curved blades are made of aluminium sheet (AIMg3) and statically and dynamically balanced together with the impeller hub or the external rotor motor used according to the quality grade G2, 5/6, 3 as per DIN ISO 1940. If desired, the wheels can also be manufactured from sheet steel with a plastic coating. The direction of rotation of the impellers is standard clockwise rotation (seen from the suction side). Counter-clockwise operation will cause overload damage to the motor. Therefore, the direction of rotation should always be checked before starting up. Electrical connection Electrical connection via external terminal box protection class IP44.
