Abstract
A filter comprises a set of bristles 1 through which the flow of gas or liquid passes, trapping particles of impurities between the bristles. Preferably the bristles are flexible and are fixed to filter base 2. The filter may take on any shape and the bristles may be of any length, shape, diameter and density. Preferably, fluid such as air passes from an open side 4 of the filter, along the bristles, through base holes 3 to the filter inside 5. Advantageously larger particles (6, Fig 2) are collected in the filter upper levels and smaller particles (7, 8, Fig 2) penetrate deeper into the filter before being trapped where the gap between the bristles is smaller. Advantageously particles are collected or trapped throughout the entire length of the filter thus providing greater filtration capacity in comparison to a conventional mesh filter.
Description
Filter
Background
This Invention is related to a Filtering Device which collects dust throughout its body.
When gas or liquid passes through a conventional filter the dust particles are mainly stopped by the surface of the Filter. These types of Filter use a filtering material working as a mesh.
After a while dust particles will block the filter's surface thereby obstructing the flow of gas or liquid.
Only a relatively small amount of the filtering material, on its surface, is utilised.
Example.
To overcome this problem the Invention is proposing a Filter which catches dust all the way through its body, from its surface right through to its core. The Filter is a Brush Filter as opposed to a conventional Mesh Filter. The filter is suitable for both gas and liquid applications.
For the sake of simplicity gas (air) filtration will be described here but liquid filtration works in the same way. The Brush Filter collects dust particles in a set of bristles which form the filter's body.
Unfiltered air is passed into the filter and through the bristles from an aperture on the side of the filter.
Filtered clean air is exhausted through the filter's permeable base.
Air will find many ways of passing through the bristles thereby avoiding blocked passages, unlike conventional mesh filters which, once their surfaces are covered, rapidly lose effectiveness and restrict flow. This design is practically free from blocking so it will remain effective for much longer.
The Brush Filter is easier to clean than convention filters. It can be cleaned simply by reversing the cycle, i.e. passing compressed air in the opposite direction from the normal flow of unfiltered air and, because the bristles are flexible, they will not trap the dust within them. Alternatively the bristles can simply be washed with water.

Introduction to Drawings
The Invention will now be described by referring to accompanying drawings: Fig. 1 shows a cross section of a Brush Filter shaped like a cylinder. Fig. 2 shows an enlarged part of this cross section. The bristles 1 are fixed at one end into the base 2. The base 2 is permeable to air.
The base 2 forms a cylinder. The base 2 has holes 3 that let ajr pass through the Filter from the open side 4 to inside 5 along the bristles as it shown on Fig 1, 2,,3.
The bristles 1 do not have to be straight or to be the same length or thickness.
If the gap between the bristles 1 is smaller than the size of a dust particle then the particles will be stopped at this spot 6. But the flow of air 4 will find alternative paths around the blocked bristles, thereby maintaining the efficiency of the filter and air flow. Larger particles 6 are likely to be collected in the Filter's upper levels whereas smaller particles 7, 8 will penetrate deeper into the filter before being trapped where the gap between the bristles is smaller. Particles will be collected, or trapped, throughout the entire length of the filter body, from the open side 4 to inside of the base 2, not just on the surface as in a conventional mesh filter; thereby providing greater filtration capacity whilst maintaining good air flow.
A Brush Filter capacity depends upon on combination of the following properties: 1. The bristles lengths * the longer the bristles the more dust can be trapped 2. The thickness of the bristles -the thinner they are the smaller the dust particles that can be trapped 3. The density of the brush bristles -the higher the density the better the filtration 4. Combination of the above A Brush Filter can be of any shape. As an example, a cylinder shape filter, is shown on and Fig. 1, 2.
