Dust Fence for Dust Capture
A Dust Fence is a barrier that is designed to capture dust. This is different to a solid wall which throws the dust high into the air as it passes over the fence.
Dust Tex Net is the only material and securing system that provides this type of dust containment system. It is also commonly called a dust wall.
DustTexNet Material
The mesh structure of the Dust Tex Net makes it washable and resistant to wind and dust. The mesh allows
air to pass through the net but not the dust which is trapped in the inner
side of the containment net and cannot escape.
The Dust Tex Net also reduces the wind speed downwind reducing dust lift off so it provides a combined function of dust and wind fence.
The Dust Tex Net is designed to be self cleaning, resist UVA rays and doesn’t lose its colour. It also maintains its mechanical characteristics for at least 5 years. The wind that brings dust onto the Dust Tex Net will also dry and shake the Dust Tex Net causing the dust to fall to the base of the net itself.
Dust Tex Net looks like shade mesh which is commonly used for small scale dust walls. Dust Tex Net is different from shade mesh in the following ways:
- Dust Tex Net is non sparking and non flammable, ideal for coal
- Dust Tex Net is self cleaning
- Dust Tex Net has electrostatic attraction of dust particles
- Dust Tex Net has finer pores capturing smaller dust particles
The Dust Tex Net material is a critical part of the Dust Tex Net installation, but the installation provides additional benefits:
- up to 55m high walls
- up to 30m between supports
- Zig zag material installation option changes the angle of impact resulting in smaller dust particles captured
- Safety material release in very high winds reducing structural support requirements and costs
- Clips stay secured to cable after release so no airborne projectiles
- Easy and quick installation and re-securing and replacement of material
This photo of a demonstration unit shows how the Dust Tex Net is secured, although in most applications the top of the material would be permanently secured (cable runs through mesh seam) and would not have the release clips.
Dust Tex Net Advantages
- Designed to stop dust particles while allowing air molecules to pass through
- Wind braking effect reducing dust lift off and dust movement
- Electrostatic attraction of dust particles to capture smaller dust particles when they impact the material
- Self cleaning through the action of the wind
- Non sparking and non flammable
- UV stable for long lifespan
- Resistant to strong winds
DustTexNet benefits over solid walls
- Solid walls create wind turbulence which can cause dust lift off
- Solid walls are more expensive
- Solid walls do not capture dust they just throw it higher
Dust Fence vs Wind Fence
Wet Earth also offers the Wind Fences. which are designed to slow the wind speed to prevent dust liftoff. This page discusses the differences between Wind Fences and Dust Fences.
