VENTS Non-insulated air ducts Thermovent series
Description
Description
DESCRIPTION |
FEATURES |
- Semi-flexible stainless or galvanized steel spiral seam air ducts with high aerodynamic and strength characteristics.
|
- Made of incombustible, corrosion-resisting stainless steel or galvanized steel band.
- Increased thermal resistance (up to 700°С).
- Superdense high-quality triple locks ensure high seam tightness and total air tightness of the ducts.
- 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: |
|
|
|
- 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.
