The working area of the weighing room is under negative pressure relative to the background area. The vertical unidirectional air flow in the working area not only ensures that the weighing dust descends with the air flow, but also does not spread to the background area, which can prevent cross-contamination, protect the clean environment and operators Security.
Technical Parameters
