Vortex Dynamic Filter

Highly efficient filtration without the need for replacement media.

The Vortex Dynamic Filter is a media free coolant filtration system which achieves filtration through centrifugal force eliminating the need for disposable paper or cartridge filters

How it Works

Fluid containing sludge flows from the supply pump into the VDF via the side port and through the inlet, which is positioned tangential to the periphery at the top of the separator.The fluid flows along the inner wall of the cyclone and the pressure energy is converted into rotational energy. Whilst turning under the strong centrifugal force, the heavier sludge descends the tapered body towards the narrow nozzle in the base of the VDF. After passing the nozzle the sludge is discharged into the sludge pod

The discharged sludge rapidly loses its rotational force, is collected in the sludge pod and collects until discharging, either manually or via a solenoid valve. Any ultra fine sludge which is unable to generate sufficient centrifugal force and descend down the inner wall of the separator, is discharged along with the cleaned fluid from the top port. During this process an area of low pressure is present in the center of the separator.
