Axial fan DAS 90 / 8 rotary current, 22,000 m3 / h, DN900

Short description: Axial fan with steel wall ring, in rotary version. For wall mounting. Protection grid on the suction side, painted. 8- to 10-leaf wing wheels made of glass fibre-reinforced polyamide. Protected against weather effects by epoxy paint. Designed for the temperature range -10 ° C to + 50 ° C. 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. Easy to use with square wall plate (accessories). Support direction: The support direction is marked. Only for ventilation (right run). Rotary current motor: Asynchronous motor. Not suitable for the production of steam-saturated air. Rating voltage 400 V, 50 Hz. Protection type IP 55. Speed control, exceptions: DAS 71 / 8, DAS 80 / 6 and DAS 112 / 8. Devices can be controlled via optional frequency inverters e.g. type MFU. The fan engine must be secured against thermal overload with a current-dependent protection device. The protection shall be provided on-site. Overload protection with built-in motor protection switch. Electric connection: In the terminal box on engine. Safety: For fans with power consumption > 4 kW, a built-in star / triangle switch must be used for the start-up current limit. The fan may only be put into operation if the contact protection of the running wheel is guaranteed in accordance with DIN EN ISO 13857, for example with Maico protection grid SG. Not subject to a transformer. Article: DAS 90 / 8, design: steel ring, conveyor volume: 22000 m3 / h, conveyor volume: 11150 m3 / h / in the opt. Efficiency, pressure pps, name: 148 Pa - in opt.
