1. Applications:

• Purpose: Initial dust filtration, used in air filtration systems and programs in HVAC units.
• Common applications: Filters larger dust particles, protecting finer filters in HVAC systems.

2. Key Features:

• Large dust filtration area: Effectively filters larger dust particles with a high level of efficiency.
• Low initial resistance: Allows easy airflow, reducing the load on downstream filters.
• High airflow capacity: Ensures good ventilation without obstructing air movement.
• High dust-holding capacity: Retains more dust, protecting finer filters.
• Single-use or replaceable: Can be used as a single-use filter or replaced based on needs.

3. Filter Media:

• Material: Flame-retardant synthetic fiber filter media that complies with European DIN 53438-F1 standards.

4. Frame:

• The frame can be made of waterproof cardboard, or metal frames such as aluminum (Aluminum), stainless steel (SUS), or galvanized steel (Galvanized).
• The frame can be customized to the customer’s requirements and is reusable, which helps reduce costs.
• Frames are treated for smooth, shiny surfaces, helping to reduce dirt accumulation and make cleaning easier.

5. Additional Features:

• High dust-holding capacity: Prevents secondary contamination, ensuring clean air.
• Special media: Non-woven fabric, fiberglass pads, nylon mesh, and metal mesh can be used to enhance filtration effectiveness.
• Environmental compliance: Used filters can be disposed of in accordance with environmental protection requirements.

6. Detailed Specifications:

• Filter grades: G3 and G4.
• Standard sizes: 59459450T, 59459425T, 59459420T, 59459410T (customizable based on customer requirements).
• Airflow capacity: Ranges from 1600 m³/h to 3200 m³/h depending on the filter size.
• Initial pressure loss: G3: 35%, G4: 45%.
• Final pressure loss: 200 Pa.

7. Customization:
Customers can request filters to be made in specific sizes and thicknesses according to their needs.
