DZF 40 / 4 B, Axial wall-in fan DZF 40 / 4 B

Axial wall mounting fan DZF 40 / 4 B underplaster, rotary current, DN400

Spin current version: Axial wall installation fan for undercleaning installation, in spin current version. Short description: To the underfloor assembly. Installation possible in any location. Wall sleeve made of galvanized steel sheet. 8-leaf wing wheels made of glass fibre-reinforced polyamide. Plastic protection belts on the suction side, pearl white, contact protection according to DIN EN ISO 13857. Thermal overload protection as standard. 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. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. Rotary current motor: type series DZF. Asynchronous motor. Rating voltage 400 V, 50 Hz. Protection type IP 55. Derogation DZF... D IP 54. Speed controllable. Devices can be switched gradually 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. exception: DZF... D. The connections are free of potential to clamps and must be connected to an engine full-length protection switch e.g. MV 25-1 or the control circuit of a protection. Not suitable for the production of steam-saturated air. Electric connection: on the terminal bar in the engine's final cover. Safety instructions: In the case of free suction, the fan may only be put into operation if the contact protection of the wheel is guaranteed in accordance with DIN EN ISO 13857.
