Introduction
Ship launching airbags are to be constructed of a cylindrical body and two conical heads (one at each end). Ship launching airbags with lots of advantages, such as easy to operate, time saving, saving investment safety, etc.






Major Strengths of Ship Launching Airbags:
High level of safety: Equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

Japan, Germany, etc. use this unit as a unit representing the performance of the sweeper, but in other regions, the input power is directly misunderstood as a unit representing the performance of the sweeper.

After reading the introduction of this article, we already know what are the characteristics of the floor sweeping robot. This kind of thing can clean the house well, especially the sundries in some dead corners. Therefore, we can choose directly according to the characteristics. In addition, the above also tells you what the principle of the floor sweeping robot is, We should use it according to what we know.
