Filter Elements - Multilayer Wire-mesh Design For High Viscosity Melts, Supports Spin Pump Pressure Up To 60 Atm And Temperatures Up To 270°c

Our Filter Elements are used in the spinning process of high viscosity melts eg. Polyamide, Polypropylene, Acrylic, ABS, LDPE and Polyester. The filters affect firstly a homogenization of the melt and secondly a filtering-off of foreign bodies or hard particles, some of Microscopic fineness, which can lead to all blocking of the jets or to faulty threads.
The filters generally consist of wire-mesh layers of varying filter fineness. The mesh with the lowest transmissibility, for instance 25 microns, determines the filtering effect. Other mesh layers with larger apertures are incorporated in the complete filter. The sturdy support cloth gives the filter an optimum strength. The aperture gradings and the order of the cloth layers are decisive for the homogenization of the melts and are therefore of great importance. Spin pump pressure up to 60 at (850 psi) and temperature up to 270A C (520A F) are no exception.
Multilayer filters are generally fitted with a frame made of aluminum or stainless steel. This frame holds the layers together, guarantees the correct order of the layers and at the same time acts as a gasket or seal.
Our filters can be round , oblong or rectangular or kidney shaped or cylinder or have any other required form.
