Canister Drainer

The Canister Drainer is a building whose Element Filter is used to designate areas for the storage of specific gases. By setting the Element Filter you define which gas type the Canister Drainer will accept or target for storage in the designated zone. This makes the building a straightforward way to segregate gas storage by element, preventing unwanted gas types from occupying the same storage area.

Use the Element Filter to mark particular tiles or a contiguous region where only the selected gas should be collected into canisters. The filter operates as an explicit designation: when configured, the Canister Drainer treats the designated area as the intended storage location for that element. This behavior allows you to organize storage areas by gas species and keep volatile or valuable gases isolated from ambient mixtures.

Practical notes and usage considerations:

• Configure the Element Filter to match the exact gas you intend to store so the Canister Drainer designates the proper area for that element.
• Use designated areas to prevent mixing of incompatible or low-priority gases with higher-value stocks; the Element Filter enforces storage targeting rather than leaving storage selection implicit.
• Plan storage zones spatially to make transfer and retrieval predictable: a clearly designated area per gas simplifies logistics and reduces accidental storage of the wrong gas.
• The Element Filter is the primary control for storage designation; ensure it is updated if your storage needs change or if you repurpose a zone for a different gas.

The Canister Drainer’s Element Filter provides a direct, game-mechanical method to control where specific gases are stored, enabling organized and reliable gas management when handling multiple gas types within a base.
