    Polyvent 600

Description
  • Flexible air duct from polyester PVC impregnated fiber and spiral high-carbon steel wire frame.
Features
  • Low pressure loss due to high wall rigidity.
  • High mechanical and abrasion resistance.
  • High chemical stability, high temperature resistance (up to +110 °С).
Recommended application
  • Applied in industrial ventilation systems operating in heavy-duty mode, incl. agricultural and pharmaceutical applications.
  • Handling of granular and granulated material, removal of chemical vapours, smoke, postwelding gases, powdered solid particles, waste chips, fibres , vapours, soot and low-abrasive dust and in environment with special temperature resistance requirements (up to +110 °С).
Pressure loss diagram per 1 m stretched air duct

Calculation example:

  1. Select a curve that matches the air duct diameter [mm], 200 mm in this case.
  2. Find the intersection point of this line with the vertical line of the required air flow in m3/h, 500 m3/h in this case.
  3. The horizontal line that shows the pressure loss in Pa per 1 m straight air duct crosses this intersection point.
  4. Multiply pressure loss value (2.4 Pa/m at 20°С) by total air duct length to get the total pressure loss value. To calculate pressure loss in case of bends consider each bend as extra air duct meter.
