DZR 60 / 4 B, axial tube fan DZR 60 / 4 B DN600, current

Rotary current version: Axial pipe fan, in rotary current version. Short description: Tube case made of galvanized steel sheet, both sides with flange. 8-leaf wing wheels made of glass fibre-reinforced polyamide. Flange drilling according to DIN EN 12220: 1998. DZR 56 / 6 B and DZR 56 / 4 B: flange drilling according to DIN EN 12220: 1998. To avoid vibration transfer to the pipe system: use elastic connection pins, feet and vibration absorbers. Thermal overload protection as standard. Ventilators meet the requirements of European ecodesign Regulation (EC) No 327 / 2011 Directive 2009 / 125 / EC. Vibration-free run by dynamically weighted wing wheel and engine (wave rotor), according to quality level 6.3, DIN ISO 1940, part 1. High ventilation-side efficiency, low operating noise. Increased durability through high-quality materials such as low-noise ball bearings. Fans are maintenance-free. Reversible operation of the fans possible. Customer-specific special voltages as special versions available on request and at an additional price. Installation possible in any location. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. Rotary current motor: Asynchronous motor. Not suitable for the production of steam-saturated air. Rating voltage 400 V, 50 Hz. High protection type IP 55. Derogation EZR / DZR... D IP 54. Speed controllable. The exception for type DZR 40 / 2 B devices can be switched with an optional 5-step transformer. Reversible. Reverse operation: The volume flow rate is reduced by about 35% with an abnormal direction of transport. Thermal overload protection as standard. Exemptions for type DZR 25 / 4 D and polo-switchable axial tube fans available on request. The connections are free of potential to clamps and must be connected to a motor full-length protection switch e.g. MV 25 or the control circuit of a protection. Polo-switchable fans: ensure overload protection with the fully-designed engine protection switch. Electric connection: external terminal box with cable cases. Safety instructions: The fan may only be put into operation if the contact protection of the wheel is guaranteed in accordance with DIN EN ISO 13857, for example with Maico protection grid SG.
