Integrated ventilator WZk 400/250 integrated acid-proof UNIWERSAL326

Integrated ventilators WZs, (k) and WZEx is a combined structure, consisting in the combination of mechanical ventilation with gravitational (natural) ventilation. Inside the proper vent, made of polyester-glass composite, there is a centrally mounted fan, which can be connected to a mechanical ventilation exhaust system, local exhaust hood, etc. with a channel ended with a mounting flange. As well as intensify it in his work. Possible places of application are rooms with high gains of heat and moisture, rooms where continuous natural ventilation should be maintained, while only periodically if necessary, mechanical ventilation is turned on (e.g. rooms with periodic pollution, warehouses during the operation of diesel forklifts, bus depots, etc. .). A frequent need in practice is the
