Galvanized Frame Panel Filter
I. Product Introduction
The Galvanized Frame Panel Filter with Frame-in-Frame Design features a unique dual-frame structure (fixed outer frame + removable inner frame), specifically developed for high-airflow, easy-maintenance ventilation systems. As the first line of defense in air handling systems, it effectively captures particles ≥5μm (dust, fibers, etc.) to protect downstream medium/high-efficiency filters and equipment.
II. Product Advantages
1. Easy Maintenance
3-Second Inner Frame Removal – Tool-free, single-person operation
Outer Frame Lifetime Use – Reduces long-term costs
2. Energy Efficiency
Low Initial Resistance (≤30Pa @ 2m/s) – 15% more energy-efficient than traditional box filters
Gradient Density Media – 40% higher dust-holding capacity, extending replacement cycles
3. Safety & Reliability
Anti-Drop Lock for Inner Frame – Prevents media detachment during replacement
V-Pleat Structure – Prevents media collapse, ensuring uniform airflow
4. Flexible Adaptability
Compatible with F5-F7 Medium-Efficiency Bag Filters (inner frame upgrade without replacing outer frame)
Custom High-Temperature Version (≤120°C) available

V.FAQ
Q1: What are the advantages over traditional filters?
| Comparison | Galvanized Frame Panel Filter | Traditional Box Filter |
|---|---|---|
| Replacement Time | 3 sec/frame | 10 min/unit |
| Long-Term Cost | Only replace inner frame (outer frame saved) | Full unit replacement |
| Space Occupancy | 30% slimmer profile | Standard box size |
Q2: Can the inner frame media be washed and reused?A: Standard version is disposable, but washable version is available (3-5 reuse cycles, efficiency drops to G2).
Q3: When to replace the inner frame?
A: Two methods:
Pressure Drop Monitoring – Replace when resistance doubles initial value
Visual Inspection – Media turns black or deforms
