Hello, In a membrane generator there are almost no moving parts. So, the maintenance would be to replace the active carbon filter, and seals, about every 2~3 years. Normal life should be 10+ years. To prevent problems, the compressor must be oil-fre

The problem you create by soldering from solder destination side (presuming you have already soldered from other side) is that you will trap air in PTH so you have virtually no continuous solder in PTH from one side to other. This will not meet IPC-A
