Ejector Upgrades can be added to machines to allow them to automatically eject their products, and are crafted like so:
Ejector Upgrades allow IndustrialCraft 2 (IC2) machines to automatically eject their products, which would only be possible with another mod which adds some form of item transfer (like pipes). Normally, Ejector Upgrades will eject to the first available side, but they can be set to only output from a specific side by shift right-clicking on any block, which will set the Ejector Upgrade to output from that side.
Adding more than 1 Ejector Upgrade to a machine ejecting to the same side has no effect, but adding several which eject to different sides will cause the machine to eject in the direction that the first Ejector Upgrade is in the upgrade slots, and will work down sequentially in descending priority.
Its counterpart for ejecting fluids is the Fluid Ejector Upgrade.
