OEM Keel V-Shape Pleat Washable G4 Aluminium Filter Overview
This product is a washable G4-grade aluminum pre-filter designed for AHU (Air Handling Unit) ventilation systems, featuring a V-shape pleated structure, high dust-holding capacity, and a standard size of 24" x 24" x 2". Below is a detailed breakdown of its key features, benefits, and applications:
1. Key Features
| Feature | Description |
|---|---|
| Grade (G4) | Conforms to EN779:2012 G4 standard, capturing coarse particles (≥5.0 µm). |
| V-Shape Pleated Design | Increases filtration area by 30–50% compared to flat filters, improving efficiency and lifespan. |
| Aluminum Frame & Media | Lightweight, corrosion-resistant, and suitable for high-humidity environments. |
| Washable & Reusable | Can be cleaned with water or compressed air, reducing long-term costs. |
| High Dust Holding Capacity | Holds more dust than standard filters, extending maintenance intervals. |
| OEM Customization | Available for bulk orders with custom branding, dimensions, or packaging. |
2. Technical Specifications
Size: 24" x 24" x 2" (standard panel size, compatible with most AHU systems).
Initial Pressure Drop: ≤25 Pa (low resistance, saving energy).
Final Pressure Drop: ≤100 Pa (recommended replacement/cleaning threshold).
Airflow Rate: Up to 3,400 m³/h (varies by system design).
Temperature Resistance: -20°C to +80°C (suitable for most HVAC applications).
3. Advantages
a. Cost-Efficiency
Reusable Design: Eliminates the need for frequent disposable filter replacements.
Low Maintenance: Easy to clean with water or compressed air, reducing downtime.
b. Performance
V-Shape Pleats: Maximize filtration area while maintaining low pressure drop.
High Dust Retention: Reduces the frequency of filter changes, ideal for dusty environments (e.g., factories, warehouses).
c. Durability
Aluminum Construction: Resists corrosion, moisture, and physical damage.
OEM Flexibility: Customizable for specific project requirements.
4. Applications
HVAC Systems: Pre-filtration in AHU units to protect downstream HEPA/ULPA filters.
Industrial Ventilation: Factories, workshops, and manufacturing plants with high dust loads.
Commercial Buildings: Offices, shopping malls, and hospitals for general air quality improvement.
Data Centers: Prevents dust accumulation on sensitive equipment.
5. Comparison with Disposable Filters
| Aspect | Washable G4 Aluminum Filter | Disposable G4 Filter |
|---|---|---|
| Lifespan | 3–5 years (with proper care) | Single-use |
| Maintenance Cost | Lower (reusable) | Higher (frequent replacements) |
| Environmental Impact | Eco-friendly (reduces waste) | Generates landfill waste |
| Initial Cost | Higher (but offsets over time) | Lower |
Recommendation:
Choose washable filters for long-term cost savings and sustainability.
Opt for disposable filters if initial budget is limited or in low-dust environments.
6. Installation & Maintenance Tips
Installation:
Ensure proper sealing to prevent bypass airflow.
Align with AHU frame dimensions for a snug fit.
Cleaning:
Use low-pressure water (avoid high-pressure jets that may damage pleats).
Allow to dry completely before reinstalling.
For heavy dust, use a soft brush or compressed air.
Replacement:
Replace if pleats are damaged or pressure drop exceeds 100 Pa.
7. Why Choose OEM?
Customization: Tailor filters to specific size, branding, or performance needs.
Quality Control: Manufactured to strict standards with consistent performance.
Bulk Pricing: Lower costs for large-scale projects.
Summary
The OEM Keel V-Shape Pleat Washable G4 Aluminium Filter is an ideal choice for cost-effective, high-performance pre-filtration in AHU systems. Its reusable design, high dust capacity, and durability make it suitable for industrial, commercial, and institutional applications.
Recommended for:
Projects requiring long-term savings and low maintenance.
Environments with moderate to high dust loads.
Sustainability-focused facilities aiming to reduce waste.
