6. Detailed Construction Requirements (As Per Buyer’s Text)

A) Filter Media & Application Requirements

1. The media must comply with the original manufacturer’s specifications (MAHLE) regarding type of media and operating conditions.

2. The filter must have OEM-equivalent approvals from qualified authorities.

3. Number of pleats: 320 ± 3%

4. Total filtration surface: 19 m²

5. Proper pleat geometry and uniformity across total filter length.

6. Presence of an internal and external neck (Spacer) used for adjusting pleat spacing along the entire filter.

B) Internal & External Wire Mesh + Caps

1. Wire mesh (inner & outer):

• Material: ST14 hot-rolled steel sheet

• Minimum thickness: 0.8 ± 0.1 mm

• Galvanized coating thickness: 15 μ ± 1 μ

2. Material of top & bottom caps:

• ST14 hot-rolled steel sheet

• Minimum thickness: 0.8 ± 0.1 mm

• Galvanized coating thickness: 15 μ ± 1 μ

3. Mesh Specification:

• Expanded metal sheet ratio: 73% ± 3% open area

• Mesh size: mesh 12 for outer mesh + inner mesh

4. Punched wire sheet: Must protect the media from damage when in contact with sharp edges.

C) Polyurethane End-Cap Requirements

1. Polyurethane (Foam) material: Must be resistant to deformation during installation or pressure changes.

2. The polyurethane end caps must have strong and durable bonding, ensuring they do not detach during the filter’s operational life.

3. Filter Media Bonding:

• Must withstand minimum pulling force of 120 kg

• Must retain bonding strength at high humidity (up to RH 100%)

• Must maintain adhesive properties between –20°C and +60°C

• Adhesive must provide complete and permanent bonding of media to the caps

• Adhesive must withstand vibrations and shocks
