1.Product Overview
Medium efficiency bag filters serve as intermediate filtration in HVAC systems, protecting downstream filters and system components. In environments with moderate air cleanliness requirements, air treated by these filters can be directly supplied to end users.
2. Construction Features
– Filter Media: synthetic fibers ,nonwoven media or imported fiberglass
– Frame: Anodized aluminum alloy profile
– Internal Support: Powder-coated cold-drawn steel wire frame
– Key Advantages:
✓ Large effective filtration area
✓ High dust-holding capacity
✓ Low airflow resistance
✓ Reusable frame structure (only bags require replacement)
✓ Cost-effective maintenance
