EC IL | Yes. You can even dump both airlocks at the same time if you figure out the flows.
Every airlock added is a source of air leaks due to the clearances required for rotation.
Any time you are using just the 1st airlock alone in sequence the second airlock will have debris pass backwards through the gaps until it seals off completely or finds a path for the air to continuously escape. If it is a continuous leak, there is less available volume to convey. If the second airlock fills up with debris/dirt and is not cleared, it corrodes internally from atmospheric moisture so it must be cleared out each time the system is shut down.
Any time you are using just the 2nd airlock in the sequence, there is slightly less available volume to convey as some air escapes through the first airlock.
Even if you plate off the out-of-service airlock when the opposite is in service, there are still corrosion issues. If you use these airlocks often enough that they don't corrode such as in a feed operation, then corrosion is not too much of an issue. But if airlocks sit most of the year, they should be fogged with oil.
Can you section the 6" line & use Morris couplings for piping connections to move the same 6" airlock (and patch piece) back and forth? | |
