HAVER & BOECKER

HAVER Spinneret-Filters are used for the fabrication of fibres made from polyester or polyamid.

Our filters are produced as discs, longfilters and cylinders. The ring fixture is generally made from aluminium, although stainless steel is also possible.

HAVER Spinneret-Filters consist of several layers of woven wire cloth. The specification is predetermined in accordance with the clients demands. Woven wire cloth with square mesh weaves up to aperture widths of 25 micrometers (= 500 Mesh) are applicated as well as Minimesh Filter Weaves in the weave types BMT-ZZ and RPD.

In order to enlarge the filtration surface area, woven wire cloth may be pleated and fabricated to spinneret-filters, too. The sequence of the different layers and the pleat geometry is individually coordinated with the filtration process.
