Paper Machine Trimming
Precision water jet trimming of paper edges to ensure uniform width and clean cuts. Proper trimming eliminates irregular edges, reduces fiber contamination, and improves winding quality.
Associated Industries: Paper & Pulp
Trimming Challenges:
- Achieving clean, straight cuts at high machine speeds
- Preventing fiber dispersion and contamination
- Minimizing water carryover to downstream equipment
Recommended Products:
V Narrow Angle Flat Fan – high impact, brass/316SS
CC Flat Fan Nozzle – 0.3–35 bar, 15°–110°
CTC-6513 Low Pressure – SS316, low pressure
💡 Engineering Tip: For paper trimming, use V Narrow Angle with 15°–30° spray angle. Position nozzles at 45° to the paper surface for clean cuts with minimal fiber disturbance. Water pressure of 20-30 bar is typically recommended.

Paper Mill Felt Cleaning
Cleaning of press felts and fabrics to maintain drainage and extend felt life. Proper cleaning removes contaminants, maintains felt porosity, and improves paper quality.
Associated Industries: Paper & Pulp
Cleaning Challenges:
- Removing paper fibers, fillers, and chemicals from felt
- Avoiding damage to felt surface and structure
- Maintaining consistent drainage and water removal
Recommended Products:
CTC Low Pressure Flat Fan – 25°–90°, 303/316SS
CCTC-2510 Disc Flat Fan – 25°, stainless steel
W Wide Angle Flat Fan – 70°–140°, 0.2–4 bar
💡 Engineering Tip: For felt cleaning, use multiple CTC nozzles across the felt width. Low pressure (3–5 bar) is recommended to avoid felt damage. Oscillating shower systems improve cleaning efficiency by distributing water evenly across the felt.

Paper Web Humidification
Control of moisture content in the paper web to improve printability and prevent curling. Proper humidity control ensures paper web stability and reduces waste.
Associated Industries: Paper & Pulp
Humidification Challenges:
- Maintaining uniform moisture across the paper web width
- Preventing edge curl and cockling
- Controlling moisture for proper calendaring and finishing
Recommended Products:
CC Flat Fan Nozzle – 0.3–35 bar, 15°–110°
W Wide Angle Flat Fan – 70°–140°, 0.2–4 bar
CCTC-2510 Disc Flat Fan – 25°, stainless steel
💡 Engineering Tip: For paper web humidification, install CC Flat Fan in the dryer section. Use sensors to control humidity levels and maintain 6-8% moisture content in finished paper. For edge control, use W Wide Angle with edge misting.
Paper · Pulp
High Pressure Paper Nozzles
High-pressure cleaning of paper machine components including headboxes, screens, and roll surfaces. Effective cleaning prevents deposits and maintains paper quality.
Associated Industries: Paper & Pulp
Cleaning Challenges:
- Removing pitch, stickies, and fiber deposits
- High pressure requirements (20-100 bar) for stubborn deposits
- Minimizing water usage and energy consumption
Recommended Products:
V Narrow Angle Flat Fan – high impact, brass/316SS
CTC Low Pressure Flat Fan – 25°–90°, 303/316SS
CC Flat Fan Nozzle – 0.3–35 bar, 15°–110°
💡 Engineering Tip: For high-pressure cleaning, use V Narrow Angle with narrow angle for impact. For roll cleaning, use CC Flat Fan with 60° spray angle. Regularly inspect and clean nozzle tips to maintain performance.

Frequently Asked Questions
What is the ideal pressure for felt cleaning?
Low pressure (3–5 bar) is recommended to avoid felt damage. Use high‑pressure (20–30 bar) only for heavy contamination with narrow angle nozzles.
How do I prevent nozzle clogging in paper mill showers?
Install self‑cleaning strainers and use nozzles with large orifices. Spiral nozzles (SPJT) are highly resistant to clogging.
Can flat fan nozzles be used for edge trimming?
Yes, but use narrow angle (15°–30°) flat fans for precise cutting. The V Series is specifically designed for this application.
What material is suitable for paper machine showers?
316L stainless steel is standard. For acidic or alkaline environments, use PVDF or ceramic‑coated nozzles.
How do oscillating showers improve felt cleaning?
Oscillating showers distribute cleaning water evenly across the felt width, preventing streaking and extending felt life by 15–20%.
What is the typical water consumption for paper machine showers?
Consumption varies by machine speed and felt type. Typically 5–20 L/min per nozzle. Using high‑efficiency flat fans can reduce usage by up to 30%.
