The Aquabox Professional has been revised and improved in various aspects compared to the previous model. Features include G1/4 connection threads, two additional connection threads on the top of the Aquabox, and a recessed stainless steel panel with sunk screws in the front panel. The Aquabox Professional is machined from solid Delrin material, making it extremely durable. The proven coolant inflow through the front panel of the Aquabox has been retained, keeping the front panel fog-free and creating a very nice visual effect. The amount of water flowing through the front panel can be easily adjusted using two stainless steel set screws in the inflow channel.
