Fire Hose
Doctor Blade Air Hose
The doctor blade air hose delivers pressurised air to the doctor blade chamber in paper making and printing, where the blade has to stay in constant contact with the cylinder.
Product Overview
What This Hose Is Built To Do
The doctor blade air hose delivers pressurised air to the doctor blade chamber in paper making and printing, where the blade has to stay in constant contact with the cylinder. It is lined in NBR, EPDM or Viton depending on the temperature the machine runs at, covering up to 100°C, 130°C, 160°C or 250°C. Sizes run from 5/8 inch to 4 inch in 30 m (100 ft) lengths.
Key Benefits
- Four liner options let the hose be matched to the actual chamber temperature instead of over-specified
- Acid and alkali resistance for the chemistry around a coating station
- Corrosion and crack resistance so the blade load stays constant between shutdowns
- Long lifetime on a component that is expensive to change mid-run

Manufacturing and Quality
How It Is Made and Checked
Production Process of Fire Hose. Every manufacturing process complies with the ISO 9001 standard.
- All raw materials approved by the Department of Quality Control
- Yarn strength and skein consistency verified before weaving
- Every manufacturing process complies with the ISO 9001 standard
- All hoses tested at the test pressure
- Layflat hose held at 1.5 times working pressure for 2 hours before shipment
- Trace number recorded for production date, employees and raw material sources
Customization Options
- Colour made to order alongside the standard range
- OEM and ODM printing of your brand, with exclusive protection of your designs
- Length cut to the run you specify rather than a fixed stock length
- Couplings fitted before shipment and pressure tested as one assembly
Use Guide
- Confirm the maximum chamber temperature before choosing between NBR, EPDM and Viton
- Route the hose away from direct contact with the heated cylinder
- Check the hose at every planned shutdown rather than waiting for a failure
- Keep the bore clean and dry so condensate does not reach the blade
- Replace on a fixed interval where the line is inside an enclosed hot zone
Comparison
How It Compares With Our Other Products
| Hot Water Hose | Both use high temperature liners, but this one is specified for pressurised air on a blade chamber rather than hot liquid transfer |
|---|---|
| Layflat Air Hose | Layflat air hose is a general compressed air line, where this is built for the temperature and chemistry beside a paper machine |
