Leaf Filters with Low Pressure Drop & High Filtration Efficiency

Leaf filters, also known as filter leaves, are the most important parts of pressure vessels with permanent filter leaves for liquid & solid filtration. Made of stainless steel construction, our filter leaves commonly consist of 5 layers of stainless steel woven filter cloth made of different wire gauges upon your request. Generally, there are 2 layers of fine filter mesh, 2 layers of supporting mesh and 1 drainage mesh. Then, the 5 layers are held together by a tubular frame to form a complete filter leaf.

Filter leaves are supplied in groups to increase the filtration area of the leaf filter, thereby improving the filtration rate and product clarity. Filter leaves can be made into various sizes and shapes to satisfy the specific requirements of your pressure leaf filters.
