Filter Leaf

Filter Leaves with A Longer Replacement Cycle

Filter leaves are filter elements installed in pressure leaf filters. Generally, 10 to 60 filter leaves are stacked inside a vertical or horizontal pressure leaf filter and filter leaves are the heart and the most critical part of pressure leaf filters.

  • Suitable for both vertical and horizontal pressure leaf filters
  • Every filter leaf consists of 5 layers of stainless steel woven mesh (2 layers of fine wire mesh, 2 layers of supporting mesh and 1 layer of drain mesh). All layers of wire mesh are bound together by a tubular frame and are made leak proof by machine riveting or bolting to offer a long service life.
  • Longer replacement period means every filter leaf enjoys a longer service life and requires a lower maintenance cost.
  • Made of stainless steel wire mesh, our filter leaves offer great corrosion and rust resistance.
  • Suitable for precoat filtration systems

Weave Type

Stainless steel woven mesh for filer leaves generally adopts plain weave, plain dutch weave, reverse plain dutch weave and reverse dutch twill weave. Generally drain mesh and supporting mesh adopts plain weave, fine mesh adopts plain weave, plain dutch weave, reverse plain dutch weave or reverse dutch twill weave.

Application

Pressure leaf filters are a closed type automatic solid-liquid separation device and can work with variety of filtering aids. They apply to decolorization and filtration, pharmaceutical oil filtration, crystallization separation process, etc. in the production of oil and grease and chemicals and are mainly used in the following industries.

  • Food & beverage. Edible oil coarse filtration, bleached oil filtration, gelatin, vinegar, starch, sugar juice, sweet water, etc.; beer, juice, wine, milk, etc.
  • Petrochemicals. Diesel oil, lubricating oil, petroleum wax, mineral oil products, etc.
  • Fine chemicals. Resins, varnishes, dyes, lacquers, etc.
  • Organic chemicals. A variety of organic acids, alcohols, benzene, aldehydes, etc.
  • Inorganic chemicals. Bromine water, potassium cyanide, fluorite, etc.
