Support Cage: Temperature Range -40°C to 150°C

Component Specifications

Definition

A cylindrical or pleated structural component designed to provide mechanical support to filter media in cartridge filters, preventing collapse under pressure differentials while allowing optimal fluid flow through the filtration system.

Working Principle

Provides radial and axial support to filter media through its rigid structure, maintaining consistent filtration surface area and preventing media deformation during pressure fluctuations and flow variations.

Materials

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