Suzhou Seapeak specializes in custom air hoses for paper machines, featuring a fluororubber (FKM) lining (stable at 250°C) and rugged polyester/PPS/aramid jackets for 100°C, 120-180°C, and 220°C+ environments. Sourced from Dupont, 3M, Daikin, and Solvay, these hoses ensure precision airflow control for doctor blade pressure adjustment and print quality. Available in custom colors, lengths, and thicknesses.
Engineered for precision and durability in paper machine applications, the Seapeak air hose is the trusted solution for doctor blade systems. While commonly known as an air hose for doctor blades, it is also referred to as a paper machine air tube or simply an air tube.
At Seapeak, we specialize in manufacturing this critical component, which features a two-part construction: a customizable, high-temperature outer jacket and a resilient FKM (fluororubber) inner lining.
To ensure optimal performance in diverse operating environments, we offer three specialized jacket materials based on your temperature requirements:
Standard (Up to 100°C): A durable Polyester braided jacket, ideal for standard applications.
High-Temperature (120°C to 180°C): A robust PPS fiber braided jacket for enhanced thermal resistance.
Extreme-Temperature (Above 220°C): A premium Aramid fiber braided jacket for the most demanding high-heat conditions.
Customization Note: All jacket options are available in a variety of colors to meet your specifications.
The core of our air hose is its superior FKM inner lining, selected for its exceptional stability and longevity.
High-Heat Durability: Guarantees continuous, reliable service at temperatures up to 250°C.
Excellent Aging Resistance: Offers outstanding resistance to weather and ozone, preventing cracks and material degradation over time.
Our FKM rubber is sourced from global industry leaders:
• DuPont (USA)
• 3M (USA)
• Daikin Industries (Japan)
• Solvay (Europe)
Custom Manufacturing:
Doctor blade air hoses can be produced with custom wall thicknesses according to the client
Connection Configuration:
·One end connects to the paper machine's air supply (compressed air line)
·Opposite end interfaces with the air inlet fitting on an enclosed doctor blade holder
Core Functionality:
Transmits compressed air to provide pneumatic pressure/vacuum for:
·Precision adjustment of doctor blade pressure and positioning
·Ensuring consistent, uniform ink metering
Critical Importance:
As a vital component of pneumatic doctor blade control systems:
·Unrestricted flow conductance and pressure stability directly determine
·Print quality integrity & doctoring performance
