Bathroom drainage, we are more worried about what? That is the serious problem of odour, because the bathroom drainage contains a relatively high proportion of organic compounds, so the problem of odour will be relatively serious, if the previous sewage lifting units, although the tank is fully sealed, but in order to balance the internal and external air pressure, there will be a passage has been kept open, which will lead to the sewage lifting units tank odour will be emitted, although there is activated carbon, but still limited, after a period of time to replace the activated carbon, more trouble. 

But with the change of the magnetic dynamic air valve, this situation can be better improved, that is, when we usually do not drain, the air valve at the ventilation port to maintain the closed state, in the drainage of a few seconds, the air valve open for the balance of air pressure, to ensure the normal drainage, and in order to reduce the odour in these few seconds out, the air valve added activated carbon, which is a double protection, the problem of odours during the discharge of sewage is solved.

Such a small detail will change the traditional sewage lifting units in the drainage of the odour problem, especially for small sewage lifting units, which can not be connected to the ventilation pipe, sometimes have the interference of odour, the design of this magnetic dynamic air valve will effectively solve the problems of odour of small sewage lifting units in the discharge process, there is no problem even if it is not placed separately in the equipment room, which is even more obvious for bathroom renovation or relocation, as it does not take up space and solves the problem.
