Filter Cage Venturi Top Cap, Bottom Cap and Chuck Joint for Cage Filters

Filter Cage Venturi, Top Cap, Bottom Cap & Chuck Joint for Baghouse Filter Cages

High-Precision End Components for Pulse-Jet Filter Bag Cages

We supply a complete set of Venturi, top cap, bottom cap, and chuck joint for filter cage assemblies used in pulse-jet baghouse systems. These components ensure stable airflow, reliable sealing, and long-term durability in continuous industrial operation.

Why These Components Matter

In a pulse-jet dust collector, the performance of the filter cage assembly directly affects:

• Cleaning efficiency
• Pressure drop recovery
• Filter bag service life
• System maintenance frequency

However, in the market, these parts are often made with reduced thickness or substandard materials, resulting in deformation, corrosion, loose fitting, or premature filter bag failure.

To avoid these problems, we use full-thickness high-quality materials and precision mold-forming to ensure consistent fit and long-term reliability.

Quality Issues Common in the Industry

In the current market, these components are often inconsistent in quality:

• Reduced thickness and material underuse → deformation during long-term operation
• Use of substandard / low-grade materials → rapid corrosion and premature failure in high-temperature or acidic environments
• Poor mold accuracy → improper fit with cage frames and tube sheet holes, causing bag abrasion and air leakage

Result: premature bag failure, frequent shutdowns, increased maintenance cost and operating costs

Our Solution

KABORY provides a complete Venturi + Top Cap + Bottom Cap + Chuck Joint set engineered for:

✅ Stable airflow acceleration during pulse cleaning
✅ Accurate cage-to-bag seating and alignment
✅ Reduced bag abrasion at contact points
✅ Significantly longer filter bag service life

All components are manufactured using:

• Full-thickness, verified materials
• Precision mold forming for consistent dimensional tolerance
• Tight cage and tube sheet fit (no looseness, no deformation)

Goal: Stronger cleaning, lower wear, longer life, lower operating cost.

Key Performance Advantages

• 15–30% improved pulse-jet cleaning strength
• Reduced mechanical wear on bag bottom and top interface
• High stability under high-temperature and corrosive conditions
• Rigid cage connection and vibration resistance
