DESCRIPTION FEATURES
  • Flexible polyurethane air duct with high-carbon steel wire frame.
  • High flexibility, wear resistance, durability, air tightness, extremely low pressure losses.
  • Heavy flammable.
  • High solvent-, gasoline- and oil vapours resistance.
  • UV- and ozone resistance.
  • Hot gases handling is possible (up to +120°С).
RECOMMENDED APPLICATION
  • Applied in industrial ventilation systems, the ideal solution for application in woodwork and timber industry, car service and fuel stations, oil refineries. Used for removal of gas mixture with high abrasive dust content. Suitable for outside installation.
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.
