DESCRIPTION FEATURES
  • Spiral seam stainless steel air ducts with high aerodynamic and strength characteristics.
  • Made of incombustible corrosion-resisting stainless steel band.
  • Increased thermal resistance (up to 800°С).
  • Specially designed high-quality locks ensure high seam tightness and total air tightness of the ducts.
  • Smooth internal surface ensures low dynamic losses.
  • Low weight and easy mounting.
RECOMMENDED APPLICATION
  • Applied in residential and industrial ventilation, air conditioning and heating systems with the maximum pressure 10 000 Pa.
  • For supply and exhaust ventilation.
  • Applied in the systems of hot air removal from boiler houses and smoke exhaust systems.

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.
