The figure below shows how to provide relatively equal air speed in the duct system with the minimum pressure loss. Small towns Populations centres (village) What is pressure loss? The systems with large air duct length and large number of grilles should incorporate...

Section 4: air capacity through this section makes 1570 m3/h. On the assumption Pressure loss calculation at the duct bends that the air duct diameter is 315 mm and the air speed is 5.6 m/s the pressure loss The diagram allows calculating the pressure loss in the tapping on the basis of bend angle, air duct diameter and air capacity. Example. Calculate the pressure loss for 90° bend, Section 5: air capacity through this section makes 1570 m3/h. On the assumption 500 m3/h. For that find the intersection point of the vertical line that shows the air that the air duct diameter is 315 mm and the...

Flexible air ducts, Polyvent and Isovent series are the air ducts with a frame made of spiral wire reinforcement with elastic covering. Semi-flexible air ducts Aluvent and Thermovent are the spirally wound air ducts made of durable and less elastic materials The flexible and semi-flexible air duct design allows easy transportation to the site in compressed condition whereas during mounting...

Semi-flexible air ducts have higher fire resistance rating: Aluvent series up VENTS air duct design The Polyvent and Isovent air ducts’ frame is made of high-carbon steel spiral Sound- and thermal insulation wire with 0.8-2 mm diameter that is covered by a film of various materials. The spiral wire must have corrosion-resistant material and be thoroughly checked to ensure its durability and defeat resistance. Isovent series insulated air ducts are the flexible air ducts covered with The distance between spiral turns is selected to ensure the air duct flexi- mineral wool and outer sleeve. Such...
