Eheim USB Interface for Professional 3e & 4e External Filters (4020740)

The Eheim USB Interface (4020740) is a genuine Eheim accessory that allows you to connect your Eheim Professional 3e or 4e external canister filter to a Windows PC via USB. Using the free Eheim ControlCenter software, you can program, monitor, and update your filter settings directly from your computer — giving you greater control and convenience over your aquarium filtration system.

The 3-metre USB cable provides flexible placement between your aquarium cabinet and computer, and the ControlCenter software is available as a free download from Eheim's website.

Important note regarding model 2075: The Eheim Pro 3e range uses model numbers 2074, 2076, and 2078 — the 2075 designation does not exist in the Pro 3e line. If you own an Eheim Pro 3 2075, please note this is a standard Pro 3 model and does not have electronic USB connectivity. This interface is compatible with the Pro 3e electronic filter models only.
