Pleated Filter Bag Cages

Pleated Filter Bag Cages Oveview

Pleated Filter Bag Cages are high-efficiency, extended-surface support structures engineered for pleated filter bags. Unlike conventional round cages, pleated cages increase the available filtration surface area by 1.5× to 3×, improving dust-loading capacity, reducing pressure drop, and extending bag life. These cages are designed for compact baghouse designs, retrofit upgrades, and filtration systems requiring higher air-to-cloth ratios, lower differential pressure, or longer service intervals.

Key Performance Benefits

  • Up to 300% more filtration area than standard cylindrical cages
  • Lower energy consumption due to reduced pressure drop
  • Improved dust release, especially with pleated spunbond or PTFE-membrane bags
  • Longer bag life with reduced mechanical stress
  • Ideal for retrofits where increasing baghouse capacity is required without modifying housing size

Pleated cages provide excellent structural support, ensuring that pleated filter media maintain their shape under airflow and withstand repeated pulse-jet cleaning without deformation.

INDUSTRIAL
APPLICATIONS

Engineered for high-temperature, corrosive, abrasive, and heavy-dust industrial environments, Pleated Filter Bag Cages deliver exceptional structural stability, long service life, and consistent filtration performance.

Cement, Lime & High-Dust Baghouse Filtration

Cement, Lime & High-Dust Baghouse Filtration

Stainless steel cages are the preferred choice for cement kilns, clinker coolers, lime kilns, and preheater towers due to their ability to withstand: constant high dust loading, abrasive particles, elevated operating temperatures, continuous pulse-jet impact.

Steel Plants, Metallurgy & Foundry Exhaust Systems

Steel Plants, Metallurgy & Foundry Exhaust Systems

Ideal for steel mills and metallurgical operations where flue gas contains corrosive fumes, high-temperature particulates, and sparks. Stainless steel cages offer: excellent resistance to oxidizing and acidic gas, stable structural support under thermal cycling, minimized risk of deformation during heavy pulse cleaning.

Waste-Incineration, Power Generation & Chemical Processing

Waste-Incineration, Power Generation & Chemical Processing

Stainless steel cages maintain mechanical strength even under extreme pH, moisture, and temperature conditions. Their smooth welded finish reduces abrasion, helping improve bag performance and lower total operating cost (TOC).

Engineering Support & Customization

Pre-Project Technical Evaluation

  • Analyse dust chemistry, humidity, and corrosion level to confirm whether galvanized steel provides adequate protection or if stainless/titanium grades are required.
  • Review operating temperature and dew-point to assess condensation risk in cement kilns, boilers, steel mills, and grain-dust systems.
  • Evaluate dust loading, particle size, abrasiveness, and stickiness along with pulse-jet cleaning intensity.
  • Check compatibility with bag type (snap-band, sew-in, cuff), bag diameter and length, and existing tube-sheet layout.
  • Estimate expected service life and maintenance cycles to choose suitable zinc coating type (hot-dip or electro-galvanized).

Quality Assurance & Testing

  • Zinc coating inspection: thickness testing, adhesion tests, and full-coverage verification to ensure no exposed steel.
  • Corrosion-resistance testing under humidity and light chemical exposure to ensure long-term rust prevention.
  • Weld quality & finishing: smooth, burr-free joints to prevent filter bag wear.
  • Dimensional checks: diameter tolerance, straightness, ring spacing, and wire alignment for stable airflow and low pressure drop.
  • Final visual & functional inspection to verify rigidity and ensure each batch meets performance requirements.
