The fan is always leaking; please help with the selection

Dear teachers, the fans used for extracting nitrogen oxides generate leaks in their seals, which causes liquid to accumulate on the floor slabs. What kind of equipment would be suitable for such conditions? The gas flow rate is 200 Nm3/h; it’s an acidic gas composed of nitrogen oxides, and there must be no leaks. The gas needs to be transported to an incineration unit located 1 km away.
It seems to have a water seal; it would be better to look for the cause in terms of operational process control. For example, the pressure control of the water seal, for reference.
The fan is fine; the issue is mainly with the sealing. If resistance to acidic gases (corrosive gases) is required, a zero-leakage sealing design is preferred. 1390-1520-390
First, address the issue of liquid presence by separating the liquid; replacing it with a mechanical seal can achieve leak-free operation.
