This ISO Certification High Fold Semi-auto HEPA Filter Paper Pleating Making Machine is a specialized industrial device engineered to process HEPA filter media (e.g., fiberglass, PP paper) into dense, uniform pleats—an core step in manufacturing high-efficiency particulate air (HEPA) filters (critical for air purification and HVAC systems).
Its standout high-fold capacity enables adjustable dense pleat spacing (via PLC control), maximizing the filter’s surface area to enhance HEPA-grade filtration efficiency. Operating in semi-automatic mode, it balances manual parameter adjustmentswith automated feeding and cutting, achieving a pleating speed of up to 70 folds/min while reducing labor intensity.
Equipped with tension control and pre-heating (to prevent paper breakage), the machine handles materials smoothly, maintaining consistent pleat shape. It supports a maximum filter paper width of 1000mm, runs on AC 380V (three-phase power), and is ideal for small-to-medium-scale HEPA filter production lines. Widely applied in air purification and industrial dust control, this machine boosts production consistency and efficiency, enabling manufacturers to produce high-performance HEPA filters for diverse air quality solutions.
