Integrated vent WZs 400/250 integrated standard UNIWERSAL329

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.
