Air filter cartridge SEFAR® X

dustfinesub-micron filtration

Overview
SEFAR® X-Series pleated filter elements provide high-performance filtration for pulse-jet baghouses by increasing usable filtration area and improving particle retention while remaining compatible with many existing baghouse systems.

Key benefits

• Enhanced production capacity: Up to 3× filtration area and reduced air-to-cloth ratio (up to 67%), enabling production capacity increases up to 25% in suitable applications.
• Extended service life: Reduced abrasion plus lower pulse pressure and frequency can extend element life up to 300% depending on conditions.
• Reduced emissions: e-PTFE membrane and advanced sealing increase submicron particle retention and can reduce dust emissions by up to 99% in membrane-equipped variants.
• Energy efficiency: Lower pulse pressure and frequency reduce energy use up to 40% and compressed air consumption by up to 10×.
• Simplified installation: Direct retrofit compatibility with many pulse-jet baghouses; elements are often shorter (up to 50%) and may not require separate steel cages.
• High-temperature capability: Engineered variants rated for elevated temperatures (examples up to ~260°C).

Variants and typical applications
Available in six variants to match process demands from standard to extreme temperatures. Typical variants include:

• X-300 — increases filtration area (approx. 2× reported), suitable up to ~190°C for spray drying and general dust filtration (e.g., TiO2, chemical processes).
• X-600 — designed for extreme-temperature stages (up to ~260°C) and demanding micronizing/oxidation steps.
• X-750 — fitted with advanced e-PTFE membrane and optimized sealing for benchmark emission control and fine-particle retention.

Design & materials

• Pleated construction with rigid geometry to increase cloth area and maintain dimensional stability.
• Optional e-PTFE membrane in selected variants for superior submicron retention.
• High-performance aluminum potting compound and materials for thermal and chemical resistance.
• Robust internal steel core often eliminating the need for separate filter cages.
• Proprietary sealing technology to minimize leakage and maintain reliable performance.

Performance highlights

• Filtration area increase up to 3× versus conventional bags.
• Production capacity improvements up to 25% in appropriate applications.
• Service life extension potential up to 300% depending on operating conditions.
• Emission reductions up to 99% with e-PTFE membrane variants.
• Energy savings up to 40% and compressed air use reduction up to 10×.

Installation & service
Designed for straightforward retrofit into existing pulse-jet baghouses without structural modification. Elements are easier to handle and install due to reduced length and integrated rigidity. SEFAR provides process optimization, installation/startup support and maintenance/monitoring services to ensure system performance.
