The Precision Welded Industrial Dust Filter Cage is a critical component for baghouse dust collectors, designed to support filter bags and ensure stable filtration performance. Produced by Botou Xintian Environmental Protection Equipment Co., Ltd.—a leader in lean manufacturing of 3D flexible tooling—this filter cage features robot welding technology and nitriding oxidation treatment, delivering exceptional precision, durability, and corrosion resistance. As a key Dust Collector Filter Cage Accessory, it is compatible with most industrial pulse jet bag dust collectors, effectively preventing filter bag deformation and extending service life. Tailored for users in manufacturing, environmental protection, and processing industries, this cage ensures consistent dust removal efficiency and reduces equipment maintenance costs.

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.
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.
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.
