The traditional air return column takes up a lot of space and is not beautiful. Installation iscumbersome.

Berbson 100mm hollow air return wall panel replaces the return air column and 100-thickhollow spring wall in the buffer room for official clothing and shoes, and the average returnair volume is 500m3/h, which improves the use of cleanroom space.

The return air module is prefabricated in the factory, and the direct installation on site isconvenient and fast, and the construction efficiency is improved.
