Premium stainless steel pleated and sintered filter elements designed for maximum filtration efficiency and continuous operation in demanding chemical and polymer environments.
Algeria stands as North Africa's industrial powerhouse, driven by a national strategy to diversify its economic model beyond raw hydro-carbon extraction into downstream petrochemistry, high-density polymer manufacturing, agricultural plastic film production, and synthetic textile spinning. Major industrial complexes across Skikda, Arzew, Hassi Messaoud, Setif, and the Greater Algiers Metropole are scaling up processing throughput to supply both domestic African markets and export routes into Europe.
Central to these continuous, high-temperature, and high-pressure manufacturing operations is fluid purity. In polymer melt extrusion (such as Polyethylene, Polypropylene, PET, and Polyamide processing), microscopic gels, carbonized degradants, and mechanical particulates severely jeopardize yarn drawability, blow film clarity, and structural integrity. Candle filter cartridges serve as the primary line of defense inside continuous polymer filtration (CPF) units and automatic backwash filtration housings.
As Algerian operators upgrade machinery—integrating European systems like Maag, Kreyenborg, and Nordson alongside Asian extruder lines—there is an imperative requirement for high-specification replacement candle filter elements. The ideal candle filter must balance high dirt-holding capacity (DHC), low initial pressure drop (ΔP), chemical inertness against aggressive catalysts, and complete cleanability for long-term cycle repeatability under harsh Saharan and coastal operational stresses.
Filtration of resin melts, intermediate polymers, and catalytic slurry lines in Skikda and Arzew refineries requiring ASME-compliant 316L sintered stainless media.
High-surface-area pleated candle cartridges eliminating gel voids and micro-flaws in plastic packaging lines operating in Setif and Oran.
Ultra-fine fiber melt spinning filtration preserving spinneret hole integrity and preventing filament breakage in hygiene material plants near Blida.
Many traditional filter suppliers offer generic woven wire meshes that suffer from structural deformation under fluctuating differential pressures (>50 bar) or premature pore blinding when processing recycled polymer blends. For Algerian industrial engineers, evaluating filter suppliers requires looking beyond price per unit to analyze Total Cost of Ownership (TCO), on-stream lifecycle, and thermal reusability.
Our OEM factory-direct supply framework bridges the technical gap by utilizing 316L Stainless Steel Fiber Felt (Metal Fiber Matrix) combined with computer-controlled multi-layer sintering. This provides up to 300% greater void volume compared to standard woven wire mesh, dramatically reducing differential pressure buildup and extending production runs by 2.5x to 4x.
| Performance Parameter | Standard Woven Wire Mesh | Standard Sintered Powder | HG 316L Sintered Fiber Felt (Candle) | Algerian Industrial Operational Benefit |
|---|---|---|---|---|
| Porosity / Void Volume | 30% – 40% | 40% – 50% | 75% – 85% | Lower initial pressure drop (ΔP); reduced energy draw on extruder motors. |
| Dirt Holding Capacity (DHC) | Low (Surface Only) | Medium (Depth) | Very High 3D Matrix | Significantly extends filtration cycle lengths between shutdowns. |
| Max Operating Temp (°C) | 300 °C | 450 °C | 600 °C | Withstands intense thermal calcination & TEG cleaning cycles. |
| Max Differential Pressure | 30 – 50 bar | 150 bar | Up to 210 – 250 bar | Prevents collapse or gel bypass during high-viscosity polymer spikes. |
| Thermal Shock Resistance | Moderate | Low (Brittle) | Exceptional Ductility | Prevents micro-fractures during rapid heating/cooling in Saharan plants. |
By implementing 3D sintered metal fiber technology into candle filter cartridges, Algerian extrusion plants reduce gel defects in film blow lines down to <0.05 counts/m², satisfying international quality criteria for food packaging and agricultural mulch applications.
In high-tonnage polymerization facilities, raw polymer melts synthesized from ethylene and propylene streams pass through massive multi-candle filter vessels containing 19 to 150 individual candle filter cartridges. Operating under high temperatures (>280°C) and extreme pressures, these candle cartridges remove catalyst fines, cross-linked gels, and metallic wear debris prior to pelletization. Our SUS 316L and Hastelloy C276 custom elements are designed with specialized threaded (NPT, BSP, or M28x1.5) and double O-ring connection hubs to guarantee zero-leak seals under Sonatrach-certified continuous operations.
With Algeria expanding circular economy initiatives, plastic recycling processors encounter heavily contaminated post-industrial and post-consumer scrap (HDPE, LDPE, PP, PET). Standard filter screens clog rapidly, causing costly downtime. Our heavy-duty pleated metal mesh candle filter elements offer high surface area within a compact diameter. They are engineered to endure high-torque dynamic backwash cycles, continuously purging contaminants without interrupting the pelletizing line.
For spunbond and meltblown nonwoven production lines producing medical drape and hygiene products, filtration accuracy is paramount. A single 15-micron contaminant can block a spinneret orifice, causing filament breakage and thread line stoppage. Our micro-rating candle filter cartridges (5μm, 10μm, 20μm absolute) employ graded density sintered stainless fiber media to capture soft gels that standard mesh screens miss.
Full customization options engineered to handle extreme pH, aggressive solvents, high temperature, and mechanical stress.
Low-carbon austenitic stainless steel offering superior resistance to intergranular corrosion in high-temperature polymer melt streams up to 400°C.
Nickel-molybdenum-chromium superalloy ideal for severe chemical applications in Algerian petroleum refining involving wet chlorine, organic solvents, and acid gases.
Provides 200% to 400% more effective filtration surface area compared to smooth cylindrical designs, minimizing vessel size and thermal mass.
Precision CNC-machined connectors: Threaded (M28, M36, NPT), Tie-rod, Bayonet, Flange, or Flat End Cap with customized Viton/Kalrez gaskets.
Our engineering team provides full CAD drawing confirmation, sample testing, and direct export documentation compliant with Algerian customs (Crédit Documentaire / LC).

One of the chief economic advantages of stainless steel candle filter cartridges over disposable synthetic media is their capability to undergo multiple cleaning and regeneration cycles (up to 15-20 cycles) without loss of filtration efficiency. For Algerian operational engineers managing high maintenance costs, we recommend the following multi-stage regeneration procedure:
Depolymerization in Triethylene Glycol (TEG) bath at 280°C or controlled vacuum pyrolysis furnace at 450°C to decompose organic polymer residues.
Immersion in high-frequency ultrasonic baths containing specialized mild acidic or alkaline cleaning agents to displace microscopic inorganic ash.
Reverse liquid back-flushing followed by clean compressed air blowing to verify clean differential pressure (ΔP) recovery.
Addressing key procurement, logistics, and technical specifications for Algerian industrial operations.
From leaf disc filters to plastic recycling machines and high-temperature extruder mesh screens for industrial plants across Algeria.
