Non-insulated air ducts Aluvent series

Flexible spiral seam aluminium band air ducts with high aerodynamic and strength characteristics.

Made of incombustible, corrosion-resisting aluminium band.
Specially designed high-quality locks ensure high seam tightness and total air tightness of the ducts.
Low dynamic losses.
Low weight, high elasticity and easy mounting.

Applied in residential and industrial ventilation, air conditioning and heating systems with the maximum pressure 10 000 Pa.
For supply and exhaust ventilation.

Select a curve that matches the air duct diameter [mm], 200 mm in this case.
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.
The horizontal line that shows the pressure loss in Pa per 1 m straight air duct crosses this intersection point.
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.
