Problems solved by technology

Many of these filtration systems pose a number of problems: in order to provide the proper degree of filtration, the life of the filter may be reduced
Likewise, if one wants to increase the working life of the filter, it is likely that at some stage the efficiency of the filter will be reduced

Embodiment Construction

[0016] figure 1

[0017] What is shown in FIG. 1 is an air purification system, wherein purification branch pipes 101 , 102 , 103 are connected to a central purification system 104 through a pipeline 105 . 50 purification branch pipes can be connected on the pipeline 105 . On the other hand, by installing multiple porous systems, the life of the filter can be extended, or by connecting a small number of systems, a rapid purification process can be achieved.

[0018] figure 2

[0019] The purification system 104 is shown in FIG. 2 , and its basic structure includes a stainless steel cabinet whose size is equivalent to that of a household refrigerator. The polluted air enters from the air inlet 201, and the purified air is discharged from the air outlet (shown in FIG. 3). LCD display 203 displays operating status, such as filter capacity that can be filtered, gas sensitivity, particle sensitivity, days until next maintenance, and warning indication temperature. Also on the f...

Abstract

A filter for air extraction apparatus is disclosed, which is assembled from a porous material arranged to collect contaminants. The filter comprises a bag with a constricted inlet for receiving contaminated air. The bag is formed from a plurality of envelopes having filtering side walls and each of the envelopes has at least one orifice connected to an orifice of an adjacent envelope.

Description

technical field [0001] The present invention relates to: a filter for an exhaust device, an exhaust device, and a method of manufacturing the filter for an exhaust device. Background technique [0002] Exhaust systems for exhausting and filtering air to remove particulate matter and gases entrained therein are well known. Such devices are used in many industrial settings, for example in the electronics industry and the pharmaceutical industry. In such assembled workstations there will be operations that generate fumes and / or dust, such as the manufacture of electronic circuit boards, requiring an exhaust system. The present applicant manufactures and sells under the trademark "Purex" a fume extraction device comprising a plurality of articulated branch pipe assemblies for the various workstations which are connected together by suitable plumbing to the pump and filter assemblies. [0003] Many types of filter assemblies are known and it has been recognized that the filter ...
