Item Filter (GregTech 6)

The Item Filter is a machine cover added by GregTech 6 that allows or forbids a single item from entering or leaving the machine. To filter multiple items, the Filter (Items) may be used instead.

Initially, the Filter has no item set and is in "Allow only" mode, and will not allow any item to pass. To set its item, right-click the item on the Filter after installing it on a machine. To clear its item setting, use a Soft Hammer on the Filter. To invert the filter such that it will allow any item except the specified item, use a Screwdriver on the Filter. The Filter will retain its item setting when removed from the machine using a Crowbar.
