For example, in a shopping mall, the air volume of the fan cabinet is 24000, the size of the static pressure box is 2000 * 600 * 600, and it is covered with sound-absorbing cotton.

The static pressure box is usually customized. The width direction should not be less than 500mm. Usually, the size of the static pressure box should be slightly smaller than that of the indoor unit.
