(Note: Please confirm the specific bolt hole pitch and diameter on the flange to ensure perfect compatibility with your equipment during practical installation.)
Nominal Size: ID 65mm, OD 208mm, Height 156mm (Note: The outer diameter refers to the main cylindrical mesh body, excluding the extended flange at the bottom).
Mounting Method: Bottom Flange interface with pre-drilled mounting holes.
1. End Cap & Flange Base (304 Stainless Steel)
Structural Details: Features a top annular end cap with a central opening (ID 65mm) and a bottom metal flange base with mounting holes. These holes are pre-drilled for secure bolting to the equipment interface.
Material Properties: Made of SUS304 stainless steel, offering excellent corrosion resistance, oxidation resistance, and high mechanical strength, making it suitable for harsh, humid, or acidic/alkaline working environments.
2. Inner & Outer Support Frames (304 Stainless Steel Expanded Mesh)
Structural Details: The filter element is wrapped with diamond-shaped expanded metal mesh on both the exterior and interior. The outer frame provides compressive strength against external forces, while the inner frame supports the filtration media to prevent collapse or deformation under high negative pressure (vacuum) conditions.
Material Properties: Made of 304 SS expanded/diamond mesh. Compared to perforated round-hole mesh, expanded mesh offers a higher open area ratio (maximizing airflow and minimizing pressure drop) and is highly impact-resistant without rusting.
3. Core Filtration Layer (Sintered Felt + Inner/Outer Protective Mesh)
Structural Details:
Primary Filter Media: Sintered Felt (typically metallic or synthetic fiber felt). The sintering process interlocks the fibers, resulting in a high-porosity, uniformly distributed structure with exceptional dirt-holding capacity.
Inner & Outer Protective Meshes: Tightly laminated to both sides of the sintered felt. These fine protective meshes prevent the fragile felt from eroding or shedding fibers under strong airflow, ensuring stable filtration efficiency.
Filtration Mechanism: Utilizes deep-bed filtration to capture fine dust particles effectively. It is also highly compatible with pulse-jet cleaning (backwashing) for extended service life.
4. Sealing Component (EPDM Rubber Gasket)
Structural Details: Installed on the contact surface of the flange base or embedded within the end cap groove.
Material Properties: Made of EPDM (Ethylene Propylene Diene Monomer) rubber. This material exhibits outstanding aging, ozone, and heat resistance, as well as excellent elasticity. When the flange bolts are tightened, the gasket compresses and deforms perfectly to fill the gap between the flange and the equipment housing, ensuring a zero-leakage seal.
Engineered for demanding industrial dust collection systems, this 208*156 mm air filter cartridge delivers exceptional filtration performance through its advanced sintered metal fiber felt media. The multi-layer stainless steel fiber felt, formed through high-temperature diffusion bonding (sintering), creates a porous depth filtration structure that achieves up to 99.99% dust removal efficiency. Unlike conventional woven wire mesh, sintered felt offers superior dirt-holding capacity and filtration precision, ensuring your dust collector operates at peak performance with minimal maintenance interruptions.
The filter layer consists of high-quality sintered felt reinforced with inner and outer protective mesh. This advanced media structure enables depth filtration—capturing particles throughout the material thickness rather than just on the surface. With porosity reaching up to 85%, the cartridge maintains high air permeability while delivering low pressure drop, reducing energy consumption and extending on-stream life by two to three times compared to conventional wire mesh media. The result is a filter that holds more dust, requires less frequent replacement, and lowers your total cost of ownership.
Built to withstand harsh industrial environments, this cartridge features 304 stainless steel end caps and both inner and outer 304 diamond-pattern mesh cages. The 304 stainless steel construction provides excellent resistance to corrosion, high temperatures (sustainable at 480°C environments), and chemical attack from acids, alkalis, and organic solvents. The diamond-pattern mesh cages offer superior structural strength while allowing optimal airflow, ensuring the cartridge maintains its shape and filtration integrity even under high-pressure pulse-jet cleaning cycles. This robust design supports working pressure differentials up to 2MPa, making it suitable for the most demanding dust collection applications.
The cartridge incorporates a high-quality EPDM (ethylene propylene diene monomer) sealing gasket that ensures an airtight seal between the filter element and the collector tube sheet. EPDM rubber offers excellent resistance to weathering, ozone, and a wide range of temperatures, maintaining its sealing properties over extended service life. The flange-type connection design enables quick, secure installation from the top of the dust collector, simplifying replacement procedures and minimizing downtime. This standardized interface ensures compatibility with most industrial dust collection systems, allowing for straightforward drop-in replacement without modifications.
This dust collection filter cartridge is widely deployed across heavy industries, including cement production, steel metallurgy, mining, woodworking, food processing, pharmaceuticals, chemical manufacturing, and welding fume extraction. In steel mills, it effectively filters high-temperature gases and removes dust and impurities from steelmaking processes. In pharmaceutical and food processing facilities, it ensures compliance with strict air quality standards by capturing sub-micron particulate matter. The cartridge is equally effective in environmental protection applications for industrial wastewater and flue gas treatment. Whether you operate a baghouse, cartridge collector, or custom filtration system, this versatile filter element delivers reliable, consistent performance across diverse operating conditions.
As a direct manufacturer, we offer full customization capabilities to meet your exact specifications. Beyond the standard 208 mm outer diameter × 156 mm height configuration with 65 mm inner diameter, we can adjust dimensions, filtration accuracy, flange types, and sealing materials to suit your equipment requirements. Our rigorous quality control ensures each cartridge meets ISO standards for collapse resistance, flow fatigue, and multi-pass performance testing. Choose TOPEP for durable, high-performance air filter cartridges that protect your equipment, ensure regulatory compliance, and optimize your dust collection efficiency—backed by factory-direct pricing and responsive technical support.
Q1: What are the advantages of a flange connection over threaded or quick-connect types?
A1：The key advantages of flange connection include:
High connection reliability: Flanges are secured with bolts, providing strong connection strength suitable for high-pressure, high-flow conditions.
Excellent sealing performance: Combined with the EPDM gasket, the flange sealing faces form a reliable static seal, effectively preventing gas leakage.
Precise installation alignment: Flanges facilitate accurate positioning during installation, reducing misalignment risks.
Easy maintenance and replacement: Flanges are easy to disassemble, simplifying periodic inspection and element change-out.
No fiber shedding: The all-metal structure eliminates the shedding issues found in traditional glass fiber or paper elements, especially critical for high-cleanliness applications.
Extended maintenance intervals: Can be repeatedly regenerated through backwashing.
Adaptability to extreme conditions: Withstands high pressure, high temperature, and highly corrosive environments.
Fully welded sealing: Components are joined by welding, avoiding aging and degradation risks associated with chemical adhesives.
