At Aurora we’ve reimagined the G81 delivery process, which defines the technical specifications of equipment you need to use. This gives you more choice, while speeding up delivery and reducing costs.
In the coming months, we’ll be making things even more flexible by releasing voltage specific G81s. Click the sections below to check their availability.
