Stainless Steel Wedge Wire Filter OD 40mm With 0.075mm Filtering Slot
Item code: OD40FOTI0.075MM-316L
 
Brief introduction

OD40FOTI0.075MM-316L wedge wire filter which is made of 316L stainless steel. The filtering slot is 75 micron . The OD is 40mm, The filtering direction is from Outside to Inside. 

Wedge Wire screen filter is a sieve made tram looped wires formed into deep wedge-shaped section. Individual wedge wires are built into 'Panels" by threading cross rods of suitable diameter through the loops. The whole is then clamped and made secure usually by riveting or putting ring nuts over the cross rod ends or by welding.
The Wedge Wire Screens can be supplied in various shapes and forms as per the requirements such as FLAT PANELS, CURVED SIEVE BENDS, CONICAL BASKETS, CYLINDERS, TROUGHS DISCS either in one piece or in segments. For curved, cylindrical and conical screens in most cases the cross rods lie along the circumference and profile wires run parallel to the axis. Occasionally this arrangement is reversed.

ADVANTAGES 

Wedge Wire Screens provide a unique combination of the most important features required for maximum screening efficiency.
1. Free Clearance 
The wedge-shaped sections of the wire form apertures that become progressively wider in a 
downward direction, thus ensuring rapid flow of material through them. Clogged and blinded apertures are reduced to an absolute minimum. 
 
2. Lateral Strength 
In our opinion no form of screening surface with apertures as fine as those of wedge wire screens, can compare with the mechanical strength and working efficiency of wedge wire. 
 
3. Percentage Open Area 
For a given aperture size, wedge wire screens have a much larger percentage of open area than conventional sieves. 
 
4. Wearing Life 
Owing to a greater wearing area being provided by flat top surfaces, wedge wire screens retain their aperture for a longer duration than round wire screens.

* Some other advantages of Looped type of wedge wire screens over other type of screens and also other type of wedge wires are 
a) Self Supporting 
b) High Abrasition resistance 
c) Low pressure drop 
d) High resistance to Vibration 

FRAMING AND REINFORCEMENT 
Wedge wire easily lends itself to a variety of Screen Panel Constructions. Many different side finishes are available, some of which are given below : 
1. Cross rods riveted at both ends. 
2. Side angle. 
3. Single side flat. 
4. Spaced double side flats.
5. Side rubber with ferrules. 
The screens are reinforced with single reinforcing flat, double reinforcing flat and combination of single and double reinforcing flats welded to end flats. However framings should be as per fitment design in the deck. Customers are required to specify framing pattern with the order. 
Special screens can be developed for customised applications not covered by the methods mentioned above.
