Following these points, you can decide the specifications of your filter!
①Outer diameter ②Height ③Mesh size (instructions are provided below). ④The size of the object you want to capture(Vantech can advise you on the most suitable mesh size for your filter). ⑤Mesh material ⑥Mesh plate material and thickness relating to the materials used for the plate.
Japanese standard mesh size is determined as the number of openings in 1 inch (25.4mm) of a screen. 100 mesh means there are 100 openings in 1 inch. If you are not sure of the optimum mesh size, please let us know the filter’s opening size or the size of the object being filtered. We can consult with you on what mesh will work best for you.
Opening is the size of the hole. Pitch is the distance from the wire core to the next wire core.
Above is the formula for calculating the opening rate of a filter. Even if the mesh is the same, the opening and opening rate can change according to the wire diameter.
Regarding the type of mesh
Plain weave type
Standard weave of the woven wire mesh .The vertical and horizontal lines keep a certain interval with each one of them intersecting. This is used with a many variety of products.
Twilled weave type
Twilled weave is used in the instance when it’s relatively difficult to weave with a plain weave, such as high mesh or a weaving wire mesh with a large net size wire diameter. Vertical lines and horizontal lines keep a constant distance, and two or more lines mutually cross over each other.
Plain dutch weave type
It is weaved in the same manner as linen is. Horizontal lines are aligned in a linen style. Since a fine mesh can be obtained with a thick wire diameter, it is excellent with drainage performance under low pressure and has outstanding durability under high pressure.
Twilled dutch weave type
Weaved in a linen-like shape using the twill weave. Horizontal lines are arranged with a twill weave. It can be produced more densely than the plain dutch weave, thus especially used when high filtration accuracy is required.
Sintered mesh type
We can sinter depending on the mesh size, number of layers, thickness you require. Sintering from single layer to 6layers. * Maximum Size: 100 × 500 mm
Sintered metal fiber cloth
Metal fiber cloth is a material that compress and sinter small metal fibers. Composed of metal fibers diameter between 0.5 and 2.0 micrometers. They itself have a high filtration rating from 2µｍ and low pressure loss. We use weaved mesh for reinforcement.
