Filter

An upgrade for the Transposer is the Filter, which can ingest item stacks.

Filters are similar to Transposers, but are capable of sucking full stacks from any container.

Right-clicking a Filter opens a GUI with nine inventory slots. A Filter without items in its inventory will ingest whole stacks of any item from the attached tube or adjacent container. Place stacks of items in its inventory and a Filter will only accept stacks of that type and number of items. This of course applies to sucking from containers too.

From prerelease 4d onwards, a Filter can assign a colour tag to items passing through it.
