It integrates unwinding, tension control, precision mini pleating, hot melt adhesive coating, cooling, and fixed-length cutting in one continuous workflow. Built for H13–H14 efficiency filters (≥99.97% @ 0.3μm), this line replaces traditional aluminum separators with hot melt glue to form rigid V-shaped pleats—delivering compact size, low airflow resistance, and consistent quality for cleanrooms, pharmaceuticals, electronics, and air purification systems.

H13 H14 HEPA filter production equipment.
 

Core Working Principle

The line processes glass fiber filter media through a synchronized sequence:

Unwinding & Tension Control: Servo-driven unwinder maintains constant tension to prevent media stretching or distortion.

Precision Mini Pleating: High-speed servo knife pleater creates uniform, tight pleats (20–300mm height, 2–35 pleats/m) with ±0.5mm accuracy.

Hot Melt Gluing: Automatic hot melt dispenser applies 160–180°C adhesive to pleat peaks/valleys, bonding pleats into a rigid pack without metal separators.

Cooling & Conveying: Extended cooling conveyor solidifies glue for stable pleat structure.

Fixed-Length Cutting: Servo cutter trims pleated packs to custom lengths, ready for framing or assembly.

 

Key Features

100% Separator-Free Design: Hot melt glue replaces aluminum separators—lighter, thinner, no metal debris risk, 30–50% smaller than traditional pleats.

Glass Fiber Media Specialization: Optimized for fragile glass fiber filter paper (H13/H14 grade); also compatible with PP/synthetic media.

High Precision & Consistency: PLC + touchscreen control; servo motors ensure uniform pleat height/spacing and precise glue application.

High Efficiency: Production speed 8–15 m/min; one operator manages multiple lines, reducing labor costs.

Low Airflow Resistance: Optimized pleat geometry minimizes pressure drop, improving energy efficiency in HVAC/cleanroom systems.

Easy Operation & Maintenance: User-friendly HMI; quick parameter changes for different pleat heights (20–100mm) and widths (500–700mm).

CE Certified & Cleanroom-Grade: Meets ISO 14644 and EN 1822 standards; ideal for pharmaceutical, semiconductor, and hospital cleanrooms.
