Wedge Wire Filters

Our wedge wire filters, cylinders and slot tubes are made from our profile wedge wires. The wedge wires are rolled and welded to support rods at regular intervals. Therefore, this gives maximum open area and strength offering you optimum opportunity for filtration. We offer a wide range of profiles and support rod options. In addition, we are able to manufacture to your bespoke specification. Wedge wire filters, cylinders and slot tubes are mainly used for filtration of liquids in industries. For example; Food and beverage, pharmaceutical, petrochemical and chemical, waste water treatment and backwash/cleaning systems. The profiled ‘v’ shaped wires give the wedge wire filters, cylinders and slot tubes, a low risk of clogging. Also, it gives them a  self cleaning effect.

We offer three different options when it comes to our wedge wire filters, cylinders and slot tubes:

Wedge Wire Filters – Axial slots

Axial Slot specification works by filtering from the inside to the outside. The profiled wedge wires are run down the length of the tube and the support rods are welded on the narrowest point of the wedge wire giving a smooth internal working surface.  In addition, the support rods are welded to the outer surface of the wedge cylinder giving profiles which are pressure welded to form the connection.

Wedge Wire Filters – Radial slots – Standard

Standard radial slot specification works by filtering from the outside to the inside. The profiled wire is welded to the support rod at the narrowest point. This gives the working outside a smooth surface.

Wedge Wire Filters – Radial slots – Special

Special radial slot specification works by filtering from the inside to the outside. The profiled wire is welded to the support rod at the widest point. As a result, this will give an interrupted internal surface due to the support bars.

We also offer a range of nozzles, laterals, centrifuge baskets and filter baskets.

FILTRATION SCREENS

CASE STUDY – WEDGE WIRE CYLINDER

Screen Systems have recently completed a project for a wedge wire cylinder used as a separator in a drainage channel in a food factory. The cylinder was created at 126mm long and 56mm O/D, made with Stainless steel 316L. It was open at both ends to be used as a separator in a drainage channel in a food factor.

CASE STUDY – WELDED WEDGE WIRE TUBULAR FILTER

Screen Systems recently completed a project for a welded wedge wire stainless steel dewatering screen. It was a welded wedge wire tubular filter with a 1mm aperture x 12S B profile. In addition, it was created using Stainless steel 304 and had external support rods, 12 SB at approx. 12mm pitch plain cylinder.
