What Should Be Paid Attention to When Purchasing a Flexible Air Duct?

Flexible air ducts are generally used for ventilation and dust removal of industrial equipment or connecting fans for ventilation and exhaust. flexible air ducts involve a wide range of knowledge. What should be paid attention to when ordering suitable flexible air ducts?

1. When purchasing a flexible air duct, the first thing to know is the size of the flexible air duct. The size of the flexible air duct can be used to narrow down some choices of flexible air ducts. For example, some large-scale sizes can only be produced with a few types of pipes, such as pipes above 500mm. flexible air ducts can only be produced with PVC telescopic flexible air ducts and 400℃ cloth-resistant telescopic air ducts. Some customers do not know how to choose the size. When purchasing the size, you only need to know:The outer diameter of the interface where the flexible air duct is connected is the inner diameter of the flexible air duct. If you know this, you can choose the appropriate flexible air duct correctly.

2. After clarifying the size of the flexible air duct, it is necessary to know the temperature range of the flexible air duct. The general flexible air duct is used to ventilate and exhaust hot air, and a heat-resistant flexible air duct needs to be used. It can be selected according to the temperature requirements of the pipeline. Choose different air ducts for different working temperatures. The higher the temperature resistance, the selected flexible air duct is more expensive. Therefore, choosing the right flexible air duct can save costs.

3. Some special high temperature flexible air ducts also have pressure requirements, for example: positive pressure air ducts for ventilation or negative pressure air ducts for exhaust air. Order different flexible air ducts according to different pressures.

4. If there is no flexible air duct with no temperature and no pressure requirements, the applicable air ducts can be selected according to the types commonly used in the industry or according to customer preferences.
