Stainless Steel Filter Bag Cage

Stainless Steel Filter Bag Cage Oveview

Stainless Steel Filter Bag Cages are high-strength, corrosion-resistant structural frames installed inside filter bags to maintain shape, ensure stable airflow, and withstand pulse-jet cleaning impacts. They are engineered for high-temperature, corrosive, abrasive, or moisture-rich industrial environments, providing superior durability and service life compared to carbon steel or galvanized cages.

Key selection criteria:

  • Material grade:SS 304 / SS 316L — Excellent corrosion resistance, suitable for acidic, alkaline, or oxidizing atmospheres.
  • Temperature resistance:up to 400–500 °C — Stable under continuous high-temperature cycles.
  • Wire diameter:3.0–5.0 mm (high rigidity) — Thicker wires ensure structural integrity during pulse-jet cleaning.
  • Number of vertical wires:8 / 10 / 12 / 16 / 20 / 24 — Higher wire count improves rigidity and prevents bag deformation.
  • Ring spacing:6″ or 8″ — Ensures airflow stability and minimizes fabric wear.
  • Cage shapes:Round, Oval, Diamond, Pleated/Star — Selected based on baghouse design and particulate loading.
  • Surface characteristics:Smooth welds, burr-free, polished finish — Prevents abrasion and significantly extends filter bag life.

Omela’s precision-manufactured stainless cages ensure stable filtration efficiency, lower total operating cost (TOC), and long-term reliability even in the most demanding dust-collection environments.

INDUSTRIAL
APPLICATIONS

Engineered for high-temperature, corrosive, abrasive, and heavy-dust industrial environments, stainless steel 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).

Pre-Project Technical Evaluation

  • Assessment of dust chemistry, temperature, moisture, and corrosion level to select the correct stainless steel grade (304 / 316L).
  • Evaluation of particle size, dust loading, abrasiveness, and pulse-jet impact conditions.
  • Verification of cage compatibility with bag diameter, length, venturi type, collar design, and baghouse model.
  • Review of operational conditions: temperature cycles, airflow velocity, and risk of bag wear.
