Trapezoidal Bag Cage

What is a Trapezoidal Bag Cage?

A Trapezoidal Bag Cage is a kind of bag cage that is specially designed filter bag support structure used in industrial dust collection systems.
Unlike traditional round cages here the trapezoidal shape enhances airflow efficiency with providing better dust release, and minimizes filter bag abrasion.
It’s ideal for high-performance pulse-jet and baghouse dust collectors thats ensuring a stable framework for the filter bag during operation and cleaning cycles.

Material Properties of Trapezoidal Bag Cage

• Base Materials: The base      matrials are Carbon steel, mild steel and stainless steel (304 / 316L).

• Surface      Treatment: Its surface is Galvanized, epoxy-coated, silicone-coated or      powder-coated

• Temperature      Resistance: It is Up to 300°C that’s depending on coating type.

• Corrosion      Resistance: completely Excellent under humid, acidic, or alkaline gas      environments.

• Welding Type: Automatic spot      welding for high strength and precision.

• Customization: Available in      various lengths, diameters, and wire thicknesses.

Main Features of Trapezoidal Bag Cage

• Its Compact trapezoidal      structural design for efficient space utilization.

• Fewer vertical      and horizontal bars ensuring better gas flow and      minimal friction on bag surface.

• It is Enhanced stability      and structural strength compared to round cages.

• Custom sizes,      coatings and connections for various dust collector      configurations.

• Smooth and      seamless welds to reduce bag wear during pulsing or shaking operations.

• Adaptable to      both pulse-jet and reverse-air cleaning systems.

Why the Trapezoidal Bag Cage is Unique Compared to Other Bag Cages

The Trapezoidal Bag Cage offers a flat-sided geometry thats which improves dust dislodging efficiency and increases the effective filter bag area. The trapezoidal frame allows for tighter filter cartridge arrangements that is reducing system bulk while maintaining airflow capacity.

Additionally, this design reduces stress points on the filter fabric that preventing bag breakage during reverse pulse cleaning which making it a durable, energy-efficient and space-optimized alternative to circular or oval bag cages.
