Spiral duct manufacturer teaches you routine maintenance of air duct

As for the cognition of air duct, I believe that most of them are no longer unfamiliar. However, in the maintenance process, there may be some need to pay special attention to. Good maintenance habits can improve the use efficiency of air duct and prolong the service life of air duct. The following will focus on several aspects.

Through long-term experience, there are three maintenance methods for air duct, which are vacuum suction loss, gas flushing and power scrubbing. Each method has its own advantages and disadvantages.

Vacuum suction loss. The specific operation method is to directly use a brush to brush the dirt on the inner wall of the pipe, which requires a larger manhole for the air duct. The disadvantage of this method is that the dirt can not be completely removed.

Gas flushing. Connect the hose with nozzle to the air duct to deliver compressed air to drive dust out of the duct.

Power wash. Use pneumatic brush or electric brush to brush dust and dirt in air duct. One of the requirements of this method is that the surface of the insulation material should not be damaged.
