The Bottom hanging ceiling grid mainly used in the second floor ceiling of the 100-level clean workshop, which can form a clean plenum to ensure that the cleanliness of the internal circulation of the clean room meets the needs of use.
Bottom hanging ceiling grid is a layer of color steel sandwich board ceiling, with the keel with lower suspension mouth bearing, the lower FFU keel rod suspended directly on the lower notch of the double ceiling grid. The two layers of ceiling directly form a cavity that can return air, that is, a plenum, which is used to circulate indoor air and achieve internal circulation, effectively ensuring cleanliness and low energy consumption.
