Filter Cages

Precision-Built Support Structures for Dust Collector Filter Bags

Overview

Filter cages are essential support structures used inside dust collector filter bags to prevent collapse during filtration and pulse cleaning. Made from mild steel, galvanized steel, or stainless steel, these cages ensure optimal airflow, effective bag cleaning, and extended bag life. Properly designed cages are critical for efficient dust collection and reduced emissions in industrial filtration systems.
