Core / Support Cage: Length Range 250-2000 mm

Component Specifications

Definition

A rigid cylindrical framework designed to provide structural integrity to filter cartridges or bags in industrial filtration systems. It prevents media collapse under pressure differentials, ensures uniform flow distribution, and maintains proper filtration geometry throughout the operational cycle.

Working Principle

Provides mechanical support through radial and axial structural elements that withstand pressure differentials across the filter media. The cage maintains the filter's cylindrical shape, prevents pleat or bag collapse, and ensures consistent surface area exposure to the fluid stream.

Materials

Stainless steel (304, 316, 316L), carbon steel (galvanized or coated), polypropylene, or other corrosion-resistant alloys depending on application requirements.

Frequently Asked Questions

What is the primary function of a filter support cage?

The primary function is to maintain the structural integrity of filter media under pressure, preventing collapse and ensuring consistent filtration performance throughout the operational cycle.

How do I select the right material for a support cage?

Material selection depends on chemical compatibility with the filtered media, temperature requirements, corrosion resistance needs, and pressure conditions. Stainless steel is common for chemical resistance, while coated carbon steel may be used for cost-effective applications.
