About us
Lenzing Technik: Filtration and Separation


30 years experience in liquid filtration, continuous improvement, high vertical integration due
to diverse manufacturing groups in house and stringent quality standards made us an inter-
national market leader in many industrial sectors.

Our applications:                                                       Our systems are filtering following fluids:

Besides a large number of applications for solid-liquid filtration in   „ Spinning solutions
various industrial sectors we are offering systems specially de-          (Viscose, acrylic, polyimide, cellulose acetate, spandex, aramide, PVA)
