Wedge wire filters are primarily made of stainless steel and alloys resistant to corrosion and abrasion. The most common materials include:
-
AISI 304 / 304L
-
AISI 316 / 316L
-
Duplex SAF 2205 / Super Duplex SAF 2507
-
Special alloys on request (904L – 926 – Titanium Gr2)
Naturally, wedge wire filters can also be produced in a wide range of dimensions and adapted to various sizes:
-
External diameters: from Ø50 mm up to over Ø1000 mm
-
Heights (axial lengths): from 50 mm up to 2000 mm
-
Angles for conical shapes: from 3° to 45°
-
Filtration slot: from 25 µm (0.025 mm) to 3000 µm (3 mm)
The unique design of wedge wire filters optimizes flow and separation thanks to:
-
Self-cleaning effect: The geometry promotes the downward fall of solids and prevents their accumulation.
-
Active external filtering surface: The triangular wire shape and the calibrated opening between the wires allow solids to be retained on the outside, while the liquid flows inside.
-
High structural strength: They maintain integrity even under high pressures and flows, thanks to a construction featuring wires welded onto longitudinal supports (support rods).
-
Optimized flow and reduced turbulence: Ideal for continuous or high-flow processes.
Other Advantages of Wedge Wire Filters
-
Narrow surface profiles available: Maximize the number of slots and increase separation capacity.
-
Inclined wires: The wires can be slightly inclined, offering a sequence of even sharper edges for greater separation efficiency.
-
Design flexibility: A wide range of customization options in terms of dimensions and curvatures.
-
Large open area: Facilitates a high flow rate.
-
Ability to create very narrow slots: Ideal for fine and precision filtration.
