Filtered nonwovens are used in wet filtration to separate solids from liquids. For the filtration of cooling lubricants and washing media of all kinds.
The quality of the nonwoven is measured at the separating capacity, the suspended particles / microparticles, ideally in the absence of pressure-loss, during filtration.
Two types of filtration will differ between surface and depth filtration.
During surface filtration, all microparticles are deposited in the surface of the filter fleece. There the pressure-loss, of the liquid to be filtered, is increased.
Compared to this, deep filtration is the case. For this purpose, more voluminous filter webs are used in which the suspended particles are collected or collected in the fiber labyrinth. This increases the degree of filtration.
The accumulated layer of metal cuttings, fine particles and other processing waste on the filter medium, both in surface filtration and deep filtration, is also referred as filter-cake.
This filter-cake contributes decisively to the improvement of the filtration.
Filters are used on many common belt filter systems such as gravity filters, pressure band filters, vacuum filters, round filters, tube filters, bag filters and basket filters.
Filter fleece of any kind, density, quality and strength as well as structure can be delivered from us. Individual cutings and filter bags, especially for your machine, are possible and various application possibilities in painting processes can be realized. You can profit from our many years of experience.
