The primary filter rotary folding machine

The Primary Filter Rotary Folding Machine is an automatic production equipment specially designed for primary filters, with the core function of accurately folding and forming filter screen materials. The equipment is compatible with filter materials with a maximum width of 700mm and a coil diameter of 800mm. Relying on 3kw heating power and 0.75kw motor drive, it achieves a stable production speed of 3m/min. Combined with 380V/50HZ standard power supply and 0.6MPa working air pressure, it provides an efficient and reliable folding and forming solution for primary filter manufacturing. Its 500kg machine weight and regular overall dimension of 400010001250mm balance operational stability and workshop layout adaptability, making it an ideal equipment for large-scale production in the primary filtration industry.

• Rotary Folding Technology: Ensures high precision and consistency in pleat formation.
• Integrated Heating System: Equipped with 3kW heating power to set the pleats permanently in the filter media.
• Adjustable Width: Accommodates various material widths up to 700mm, offering production flexibility.
• Stable Material Feeding: Supports large material coils up to 800mm in diameter for continuous operation.
• Focused Function: Specially designed for the folding and forming of filter screen materials in primary filters, with functions precisely matching core production needs.
• Stable Parameters: Core operating parameters (production speed, heating power, motor power, etc.) are set in a standardized manner, with strong controllability during operation.

• HVAC Filtration: Production of pre-filters for commercial and industrial HVAC systems.
• Air Purifiers  Folding filter media for household and office air purification units.
• Industrial Dust Collection: Manufacturing of filter elements for dust collection systems.
