matched equipment
　　BDW-87-3 type roof ventilator could be matched with ZK type auto valve developed by ourselves. When it is getting cold , the valve will close automatically to prevent the inlet of cold air. The types of valve are the same with matchable ventilators. The height of ventilator will keep the same after installing the valve.
　　 BDW-87-3 type roof ventilator could also be used with XS type sound attenuator case, which could make the noise level lower 3-15DB（A）. The size and type of them are matched with ventilators, the height is 2 times of the chosen ventilator.
