Low Noise Fan Filter Unit Feature

1.The low noise fan filter unit has direct-drive high-efficiency centrifugal fan. It has the advantages of low noise during operation, small vibration, and stepless speed regulation. The energy efficiency ratio is high and the heat generation is small, which further reduces the heat generation of the additional work area.
2.The cabinet and high-efficiency filter are designed in a split design, making installation and replacement more efficient and easier.
3.It is especially suitable for assembly into ultra-clean production lines, which can be arranged as a single unit according to the process requirements, or multiple lines of assembly lines with high cleanliness level.
