Products and Technologies

High precision filter technology

A standard of the solid-liquid separation with the world's narrowest slit

Wedge Wire Screen

●Wedge wire screen

-A screen (sieve) in which "▽" shaped wires are arranged at equal intervals to form slits.

-The widened slit structure reduces clogging of solids and enhances the cleaning effect.

-Higher strength and durability than wire mesh.

Cross section of wedge wire

●Fine Wedge®

-A metal filter realizes slit formation in units of several microns while maintaining the characteristics of wedge wires.

-With high slit accuracy, slit guarantee is possible with stricter quality control than JIS standard for industrial woven wire mesh.

-Environmentally friendly because it can be used repeatedly instead of disposable filters such as filter paper and filter cloth.

Original equipment using wedge wire

Manufacture equipment related to "filtration and separation"


●Ultra TN screen

・ More than 20,000 units of cumulative shipment as SS (suspended substance) removal equipment for wastewater treatment.

・ Wedge wire can remove solids of 0.1 mm or more.

・ In addition to food-related factories, the products are used at various locations, such as chemical processing, paper manufacturing, dairy farming, snow melting equipment, etc.



-Removes finer solids and supports not only wastewater but also production processes and filtration of circulating water.

-Equipped with a fine wedge, it can remove solids less than 0.1 mm.

-Many applications such as removal of resin and fibers in circulating cleaning water,
papermaking white water collection, blue-green algae collection, and concentration of sludge.

In-house integrated production from test evaluation / design to manufacturing
