Industries – Reduce Downtime with Durable Filter Cages
Precision-Engineered Carbon Steel Construction
Ensures structural integrity and resistance to deformation under high-pressure filtration conditions.
Galvanized & Organic Silicon Anti-Corrosion Finish
Extends cage lifespan by 40% in humid or chemically aggressive environments.
8-24 Longitudinal Wires (Circular) / 10-16 Wires (Oval)
Optimizes airflow distribution and prevents filter bag sagging during operation.
200mm Ring Spacing
Reduces pressure drop by 15% compared to standard spacing, lowering energy consumption.
Features
Manufactured from carbon steel, galvanized steel, or stainless steel with galvanized organic silicon spray anti-corrosion treatment. Available in circular (8-24 wires) and oval (10-16 wires) configurations. Single-section or screw-joint types with 200mm ring spacing. Compatible with polyester, Nomex, PPS, and PTFE filter bags.
Benefits
Reduces maintenance costs by 30% through corrosion resistance and precise bag fit. Improves system efficiency by 12% via optimized airflow design. Extends filter bag lifespan by 25% through proper support. Compliant with industrial standards for mining, cement, and steel production.
Use Cases
Ideal for high-dust environments in cement plants, limestone quarries, steel mills, and aluminum smelters. Used in asphalt mixing stations, biomass power plants, and chemical processing facilities. Effective for solid-liquid separation in food processing and pharmaceutical industries.
