The EVAK series vacuum air knife is not only designed to remove water from the strands, but control the water after it has been removed. A conventional air knife only blows the water off the strands, whereas the EVAK uses vacuum induced airflow to aid this removal. The specially designed cyclone separation system removes the water from the air and collects it before draining the water through a check valve. This water can then be reclaimed and re-used in the system.

The EVAK is designed with a, chrome coated, hardened stainless steel vacuum comb that allows each strand to occupy its own slot producing optimal water removal and control. Be sure to ask a BPM representative for a list of upgrade options.
