The Primary Effect Plate Folding G4 Flat Middle Effect Bag Dust Removal Filter with Replaceable Cotton Cleaning Filter is a multi-stage air filtration system designed for industrial and commercial applications requiring efficient dust removal. Below is a detailed breakdown of its components, features, and applications:
1. Key Components & Filtration Stages
A. Primary Effect Plate Folding Filter (G4 Grade)
Function:
Acts as the first stage of filtration, capturing large particulate matter (e.g., dust, lint, fibers, and coarse debris).
Prevents clogging of downstream filters, extending their lifespan.
Grade (G4):
Follows EN 779:2012 or ISO 16890 standards, with an average efficiency of 40–60% for particles in the 3–10 µm range.
Suitable for pre-filtration in HVAC systems or industrial ventilation.
Design:
Pleated (folded) structure increases surface area for better dust retention.
Flat panel or rigid frame for easy installation in ductwork or filter housings.
B. Middle Effect Bag Filter
Function:
Serves as the secondary filtration stage, capturing finer particles (e.g., smoke, mold spores, and smaller dust fragments).
Provides medium-efficiency filtration before high-grade filters (if used).
Design:
Bag-style construction with multiple pockets for enhanced dust-holding capacity.
Made from synthetic fibers (e.g., polyester, polypropylene) for durability and resistance to moisture.
C. Replaceable Cotton Cleaning Filter
Function:
Acts as a maintenance-friendly option for cleaning or replacing the filter media without discarding the entire unit.
The cotton layer can be washed or replaced, reducing operational costs.
Advantages:
Cost-effective: Only the cotton layer needs replacement, not the entire filter.
Eco-friendly: Reduces waste compared to disposable filters.
2. Applications
This multi-stage filtration system is ideal for:
Industrial Ventilation Systems:
Metalworking, woodworking, food processing, and pharmaceutical manufacturing.
Commercial HVAC Systems:
Shopping malls, hospitals, schools, and office buildings.
Paint Booths & Spray Rooms:
Removing overspray and particulates to protect equipment and improve air quality.
Dust Collection Systems:
Capturing airborne dust in workshops, warehouses, and factories.
3. Advantages
High Dust-Holding Capacity:
The pleated primary filter and bag-style middle filter trap large volumes of dust without frequent replacement.
Extended Filter Lifespan:
The primary filter protects the bag filter, reducing wear and tear.
Cost Efficiency:
Replaceable cotton layers lower long-term maintenance costs.
Easy Installation & Maintenance:
Modular design allows quick replacement of individual components.
Versatility:
Suitable for both new installations and retrofits in existing systems.
4. Technical Specifications (Example)
| Component | Material | Efficiency (EN 779) | Recommended Airflow | Max. Temperature |
|---|---|---|---|---|
| Primary Plate Filter (G4) | Synthetic fibers (PP/PET) | 40–60% (3–10 µm) | 1,000–5,000 m³/h | 80°C (176°F) |
| Middle Bag Filter | Polyester needle felt | 80–90% (1–5 µm) | 2,000–10,000 m³/h | 120°C (248°F) |
| Replaceable Cotton Layer | Washable cotton | N/A (pre-filter) | Adjustable | Up to 60°C (140°F) |
5. Maintenance & Replacement
Primary Filter (G4):
Inspect monthly; replace every 3–6 months depending on dust load.
Middle Bag Filter:
Replace every 6–12 months or when pressure drop exceeds recommendations.
Cotton Layer:
Wash or replace every 1–3 months for optimal performance.
6. Example Use Case
A woodworking shop might use this system to:
Primary Filter (G4): Capture large wood chips and sawdust.
Middle Bag Filter: Remove finer dust particles from sanding and cutting.
Cotton Layer: Provide an additional pre-filter stage that can be cleaned regularly, reducing downtime.
Final Thoughts
This multi-stage filtration system combines efficiency, cost savings, and ease of maintenance, making it an excellent choice for industrial and commercial dust removal applications. If you need custom dimensions, higher-efficiency options (e.g., F7/F8), or specific certifications (e.g., ATEX for explosive environments), consult with a filter manufacturer for tailored solutions.
