To increase air intake, a front air intake shroud was designed to replace the previous exhaust mesh (the previous exhaust mesh had an outer diameter of 74cm, which can be found in the files uploaded to nexprint on my homepage). It supports fans with a length and width of 9.2cm and a thickness of 2.5cm. The shroud is integrally molded and can be directly fitted onto the exhaust mesh. It is recommended to use a potentiometer to control the fan speed for optimal performance.
