How to filter items out in a itemduct

[Stimo]

Is there anyway possible to filter items that go through the item duct?

For example I have a zombie pigman farm using auto-spawner and grinders.. but i dont want the swords or the rotten flesh, is there a way to filter this to go to the void but get the golden nuggets still?

Easily. Add pneumatic servos then right click a connection to use the GUI on the ducts to filter.

Add a nullifier to your network and it'll take care of it. Just set your filters up correctly.
