Layer Stainless Steel Filter Leaf Panel For Pressure Filters

Our stainless steel filter leaves are custom-manufactured into two primary geometric designs based on your pressure vessel's manifold orientation:

 

Rectangular Heavy-Duty Design

It features a heavy-duty outer reinforcing frame and integrated top lifting handles to withstand extreme cake weight and intense mechanical vibratory cleaning cycles without sagging.

Circular / Disc Design

This circular disc configuration is engineered for specialized vertical pressure filters, nutsche filters, or multi-plate pilot systems. The rounded border ensures perfectly uniform pressure distribution along the entire rim circumference, eliminating high-stress concentration points during filtration.

 

The exceptional separation efficiency and mechanical durability of this specific panel are achieved through a high-precision, multi-layer synchronized wire mesh matrix. Depending on your process requirements, the structural sequence can be customized into 3-layer, 5-layer, or 7-layer configurations, with each layer fulfilling a distinct mechanical or hydraulic function:

Outer Active Filtration Faces: Woven in an ultra-dense Plain Dutch Weave or Twill Dutch Weave (such as 24 x 110 mesh). By combining thick warp wires with tightly compacted, fine weft wires, this layer establishes a precise micro-gap layout. It delivers exact nominal filtration ratings while presenting an ultra-smooth, low-friction outer topography that facilitates instantaneous cake release during discharge cycles.

Intermediate Binding & Drainage Support Layers: Fabricated from medium plain weave meshes (such as 20 x 20 mesh). These layers act as a fluid-permeable, protective cushion. They prevent the fine outer filtration mesh from sagging or stretching into the large openings of the central structural core when subjected to heavy differential pressures, completely eliminating localized mesh blinding.

Central Structural Drainage Core: Composed of a heavy-gauge, massive square mesh or crimped wire screen (such as 4 x 4 or 8 x 8 mesh) with thick wire diameters. This rigid internal skeleton prevents panel buckling under high-pressure spikes (up to 6.0 bar) and functions as a high-flow internal drainage highway, allowing clarified filtrate to drop rapidly toward the discharge nozzle.

Precision CNC-Machined Nozzles: The bottom discharge nozzle is the critical single point of exit for the filtrate. Our nozzles are CNC-turned from solid SS304/SS316L bar stock to match your manifold receiver precisely. Equipped with dual Viton or PTFE O-rings, they guarantee a 100% airtight, zero-bypass seal that prevents unfiltered slurry from contaminating the clean stream.

Riveted Border Integrity (Standard): For standard high-vibration systems, the multiple layers of wire cloth are uniformly tensioned and locked permanently into a heavy-gauge, U-shaped perimeter frame using heavy-duty stainless steel rivets. The rivet spacing is calculated to absorb continuous pneumatic shaking forces without stretching or loosening.

Bolted / Removable Frame Engineering (Optional): To optimize long-term operational budgets, we offer a bolted frame configuration. This allows your maintenance technicians to unbolt the outer profile on-site and replace only the outer filtration mesh panels if they become worn or punctured, salvaging the heavy internal drainage core and drastically lowering replacement costs.

Absolute Flawless Filtrate Purity: The integration of CNC frame alignment, automated spot-welding mesh fixation, and premium sealing gaskets guarantees zero bypass leaks, ensuring your process stream consistently meets strict clarity compliance.

Minimized Total Cost of Ownership (TCO): By utilizing mill-certified, premium-grade stainless steel alloys with optimized nickel and molybdenum content, our filter leaves withstand hundreds of aggressive chemical cleanings, acid steeps, and ultrasonic restorations without suffering from structural corrosion or wire thinning.

Maximum Throughput, Minimum: The open-area ratio of our internal structural drainage core is mathematically optimized to minimize internal hydraulic resistance. This allows your pressure leaf filter systems to operate at lower differential pressures while maximizing daily processing volumes.
