摘要 |
<p>The present invention is a system of symmetric guides (25A, 25B) and baffles (26, 28) for directing and diffusing the external air drawn from a fan blower (12) before distributing the flow evenly to the outlet of a fan filter unit (32). This arrangement not only reduces the turbulence and minimizes pressure loss within a fan filter unit (32) but also maintains the even distribution of air when discharged through the same system. Furthermore, the present invention is implemented in dimensions substantially similar to that of the fan blower (12) in terms of heights. As such, the present invention minimises noise of a fan filter unit (32) even in low clean room ceiling height. Finally, the present invention's guides (25A, 25B) and baffles (26, 28) are symmetrical surrounding the fan blower (12), which allows either the clockwise fan or the anti-clockwise fan to be used for the same fan filter unit (32) for user's convenience.</p> |
