Description

Technical Field

[0001] The utility model relates to the technical field of FFU fans, in particular to a silent FFU fan component. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. FFU fan filter units can be connected and used in modular ways, making FFU fan filter units widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms and laminar flow hoods.

[0003] Prior Art Authorization Publication No. CN218511099U discloses a novel FFU (Frequency Function Unit) fan comprising a housing with an air inlet and an air outlet positioned opposite each other. The housing is provided with a first vertical panel and a second vertical panel, which, together with the housing, form four equally spaced ventilation chambers. The air inlet and air outlet are located at either end of the ventilation chamber. Each ventilation chamber is provided with a mounting plate, on which a fan is mounted. A filter is provided on the housing, which forms the air outlet, and covers the four ventilation chamber outlets. The fan and filter are located on either side of the mounting plate. The two vertical panels, first and second, which, together with the housing, form four ventilation chambers. This allows the four fans to provide high airflow while ensuring that the air flow within each ventilation chamber is independent of each other, eliminating the problem of localized filtration variations within the filters. A pressure differential monitor monitors the pressure differential between the inside and outside of the housing in real time, facilitating timely adjustment of the fan's wind speed.

[0004] The prior art generally adopts a fan-type blower for use, but when it is used, some noise is generated due to the rotation of the fan, and the user experience is poor. Utility Model Content
