Precision-Welded Industrial Dust Filter Cage for Baghouse

Dust Filter Cage, also known as filter bag cage or filter bag support cage, is the core supporting component of pulse-jet bag dust collectors. It serves as the essential skeleton for filter bags, preventing filter media from collapsing, deforming, or clogging during the equipment operation and pulse cleaning cycles. Paired with electromagnetic pulse valves, it forms a high-efficiency dust removal system, widely used in industrial flue gas purification and dust control projects

Core Competitive Advantages


Ultra-Precision Robot Welding Technology

Adopting robot welding workstations and 3D flexible combination fixtures, the filter cage achieves welding precision within ±0.1mm. The uniform spacing between vertical wires and rigid horizontal rings ensures the filter bag maintains its shape during operation, avoiding dust leakage caused by bag collapse or misalignment. The seamless welding seams eliminate burrs, preventing filter bag abrasion and extending its service life by 50% compared to traditional manual welding cages.


Superior Anti-Corrosion & Wear-Resistant Treatment

All components undergo professional nitriding oxidation treatment, forming a dense protective layer that resists moisture, chemical corrosion, and high-temperature oxidation. The surface is further sprayed with rust-proof lubricant, reducing friction between the cage and filter bag during installation and operation. This treatment ensures reliable performance in harsh environments such as chemical plants and waste incineration facilities.


High Compatibility & Structural Stability

The Durable Welded Filter Cage for Pulse Jet Baghouse is designed to match standard and non-standard filter bags, with precise diameter and height dimensions to ensure a tight fit. The reinforced top and bottom flanges enhance load-bearing capacity, while the lightweight yet sturdy steel structure minimizes airflow resistance, optimizing the dust collector’s overall efficiency.
