Embodiment Construction

[0022] A device and a method for minimizing the noise generated in the blower filter device are described below. In the following description, in order to thoroughly understand the present invention, many specific parts such as guide bodies and baffles are proposed. For other examples, for the sake of clarity of the present invention, well-known parts such as the motor used for the blower impeller and the duct connected to the blower filter device are not shown.

[0023] Fig. 1 is a right exploded perspective view showing the present invention assembled as a part of a blower filter device 10 (filter not shown). The blower filter device includes a blower impeller 12 mounted on a base plate 14, a top housing 16 and corresponding side housings 22. The blower impeller is supported on the base plate by a fixing member 20 on the bottom surface of the base plate. Not shown in the figure but what is required for the normal operation of the blower filter device 10 is an electric motor inst...

Abstract

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.

Description

Technical field [0001] The present invention relates to a device and a method for minimizing the noise generated by an air flow device. In particular, the present invention relates to a system for reducing noise generated by blower filter devices in indoor cleaning facilities. technical background [0002] Generally, in order to ensure the quality of output, modern production and testing equipment must control particles in the air circulating in indoor clean facilities. Whether it is a wafer mold, a DVD player, or a storage disk drive, an effective blower filter device is required, which can not only keep the particle content in the clean room at an acceptable level, but also circulate the air that the workers breathe. [0003] However, such a powerful blower filter device can generate a lot of noise. It is well known that sound insulation materials can be lined along the duct or in the blower filter device to reduce the noise generated by the blower impeller. However, after a ce...
