There are many changes in the design and placement of the ventilation components on the back of the machine.
PSU fans. There are changes in the placement of PSU fans in the controller box.
PSU air intake fans. Dust filters have been added to the PSU air intake fans on the right side of the controller box.
Vertical, Horizontal Ventilation Ducts. The vertical ventilation duct [A] and horizontal duct [B] have been modified to make them stronger and easier to remove.
Transverse ducts better constructed. A seal has been added at [A] for a tighter fit at the joint to prevent air leakage. The duct [B] has been enlarged to increase the volume of air moving through the duct. The joint [C] has been changed to a “snap-fit” design to make re-assembly easier and to provide a tighter seal.
Vertical duct. The duct has been enlarged to increase air flow. The bracket [A] of the ozone exhaust fan has been enlarged to provide better stability. A dust filter with a tight cover has been added at [B]. The joint at [C] between the vertical and horizontal duct has been changed to a “snap-fit” design to make re-assembly easier and to provide a tighter seal.
Horizontal duct. The horizontal duct of the previous machine [A] and this machine [B] both have two dust filters and one ozone filter. However, the dust filters [1] and [2], and ozone filter [3] are closer together in the previous machine [A] but they are spread farther apart in the new machine [B]. Fan [4] was replaced with a new type of fan and with its own cover to provide a better seal between the fan and duct.
