A METHOD AND APPARATUS FOR MINIMISING NOISE FROM FAN FILTER UNIT

摘要

The present invention is a system of geometric guides and baffles for directing and diffusing the external air drawn from a fan blower before distributing the flow evenly to the outlet of a fain filter unit. This arrangement not only reduces the turbulence within a fan filter unit but also maintains the particle count of air drawn through the same system. Furthermore, the present invention is implemented in dimensions substantially similar to that of the fan blower. As such, the present invention minimises noise of a fan filter unit even in confined clean room facility.
