10 Leading G4 Bag Filter Suppliers in the world 2025

Introduction to G4 Bag Filter

G4 bag filters are a type of air filtration device commonly used in ventilation and air - conditioning systems. They operate at the pre - filtration stage, capturing relatively large particles such as dust, pollen, and lint. With a filtration efficiency typically ranging from 90% to 95% for particles sized 5μm and above according to the European standard EN 779, G4 bag filters protect downstream filters and equipment from excessive contamination. Their design features multiple fabric bags suspended from a frame, which increases the surface area available for filtration and thus enhances the overall filtration capacity. This makes them cost - effective and efficient solutions for maintaining good air quality in various industrial, commercial, and residential settings.
