Flexible ventilation inserts are additional components that significantly improve the performance of air duct systems. They are perfect for both domestic and industrial use. Basically, flexible inserts for ventilation are needed to reduce the level of vibration of ventilation channels during the operation of units. In addition, inserts can help compensate for the thermal expansion of ventilation ducts. This helps to extend the service life of the nozzles.
These devices are very lightweight and not designed for heavy loads. They can withstand various temperature fluctuations, but mostly the nominal values range from -40 ° C to +80 ° C.
Flexible inserts are usually made of galvanized steel, using polyethylene tape and textile fabric. Additionally, vibration isolation material can be used to improve performance. The design of the flexible insert itself consists of two connected flanges. They are connected to the ventilation ducts using bolts and nuts.
Flexible inserts are divided into 3 types:
• round;
• rectangular;
• square.
Flexible fan inserts offer a number of key advantages, including the following:
• Reduced vibration levels;
• Compensation for thermal expansion;
• Improving the functioning of ventilation equipment;
• Extension of the service life of the nozzles;
• Lightweight and easy installation.
