Industrial-grade automatic heavy-duty air filter pleating production line integrating uncoiling, pre-slitting, steam conditioning, pre-heating, and roller marking. Features a customizable 300–1000 mm pleating width and 15–100 mm pleat heights. If your workshop requires compact, standalone folder systems instead of a full continuous line, please view our Automatic Zig-Zag Rotary Air Filter Paper Pleating Machine or our Precision CNC Knife Pleating Machine.
This industrial Heavy-Duty Air Filter Pleating Production Line is a fully integrated, high-capacity system engineered for the continuous manufacturing of pleated filter elements. It is designed specifically to process heavy cellulose filter paper, glass fiber media, and synthetic non-woven materials used in manufacturing heavy-duty truck air filters, agricultural machinery filters, and commercial HVAC panel filters.
The continuous line integrates an automatic paper uncoiler, raw material pre-slitting, a water steam conditioning device, an electric pre-heating plate, high-precision roller marking, and automated pleat folding in a single, synchronized setup. This advanced automated configuration drastically reduces manual handling, guarantees perfect pleat geometry under high speeds, and ensures maximum production efficiency for medium-to-large-scale filtration factories.

Key Features & Mechanical Advantages
1. Fully Integrated Continuous Workflow
The entire line combines uncoiling, slitting, steam softening, pre-heating, and folding into one automated workflow. This eliminates the need for standalone transfer machines, reducing labor costs and eliminating material damage during transit between separate processing stations.
2. Built-in Steam Conditioning & Pre-Heating
To fold thick, heavy-duty truck filter paper at high speeds without fiber breakage, the line features an integrated water steam device and a digital pre-heating plate. The steam softens the cellulose paper fibers, and the pre-heating plate dry-cures the resin, ensuring crisp, permanent folds with zero-crack structural integrity.
3. Centralized PLC & Touchscreen HMI
All parameters—including the variable-frequency line speed, independent heating temperatures, steam injection rates, and electronic pleat counting—are managed through a centralized PLC dashboard. This digital system allows operators to adjust line specs on-the-fly and save multiple filter product recipes.
4. Chrome-Plated CNC-Ground Marking Rollers
The critical roller marking unit features high-precision rollers machined from premium tool steel, finished with a hard-chrome wear-resistant coating. This heavy-duty assembly provides uniform pleat indentation across the full 1000 mm width, ensuring perfect vertical pleat alignment.
Applications & Industrial Uses
This automated heavy-duty pleating production line is the core system in factories manufacturing:
Heavy-Duty Truck Air Filters: Folding dense, deep-pleat paper elements designed for commercial vehicles, mining trucks, and agricultural tractors.
HVAC Panel and Pocket Filters: Continuous processing of synthetic and fiberglass non-woven media for commercial air conditioning units.
Industrial Dust Collection Cartridges: High-throughput folding of chemical-resistant polyester media for industrial exhaust systems.
Why Partner with Fupei?
Strict Pre-Shipment Trial Testing: Every heavy-duty pleating production line is fully assembled and tested with actual filter paper rolls at our facility to verify temperature, steam, and speed synchronization before dispatch.

Global Technical Assistance: We provide a comprehensive 1-year warranty, complete electrical and pneumatic schematics, and permanent remote video troubleshooting support to ensure your workshop maintains continuous production.
Frequently Asked Questions
A: Thick air filter paper is often brittle and can crack when pleated at high speeds. The steam conditioning unit infuses moisture into the cellulose fibers just before marking, making them flexible and pliable, ensuring sharp pleat edges without micro-fracturing the media.
A: Yes. The pleating height is adjustable within the 15 to 100 mm range. To achieve major pleat height adjustments, the marking rollers can be easily swapped or mechanically adjusted on the front assembly, supporting diverse filter specifications.
A: The line features an automatic pneumatic tension controller attached to the paper de-coiler. This system automatically compensates for the changing weight of the raw filter paper roll, ensuring flat, uniform media feeding without slippage or tearing.
