Polyvent 6061

Description

DESCRIPTION	FEATURES
Flexible PVC air duct with spiral high-carbon steel wire frame.	Low pressure loss due to extremely high wall rigidity. The service life is equal to that one of the galvanized air ducts. High abrasion resistance. High mechanical and chemical resistance, heavy-flammable, flame-retarding, self-extinguishing.
RECOMMENDED APPLICATION
Applied in residential, commercial and industrial ventilation and air conditioning systems operating in heavy-duty mode. Humid air removal, removal of smoke, post-welding gases, powdered solid particles, waste chips, fibres, vapours, soot and low-abrasive materials.

Pressure loss diagram

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 °C) 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.
