Product information

The Weighing Booth, also known as Negative Pressure Room is a dedicated local decontamination unit that conforms to the latest version of GMP for the production of sterile formulation. It provides a vertical unidirectional airflow with a fraction (80% - 90%) of clean air circulating through the working area, and another fraction (10% - 20%) discharged to the vicinity of the working area to provide negative pressure to prevent dust spill and cross-contamination in the work area, in order to ensure a high degree of cleanliness of the working environment.




1.Various styles can be customized.

2. Unique designed air duct effectively controls the noise.

3. Smooth transitions of wall and ground can eliminate the blind angle.

4. Differential pressure gauge is equipped to real-time monitor the filters.

5. Intelligent control mode and alarm system ensure the reliability of running.

6. Automatic changeable frequency system monitors the air velocity to ensure its stability in the work area.

7. Uniform flow design of main working area can protects the operators and prevent environmental pollution

and cross contamination of products.

8. Dispensing Booth(Sampling or Weighing Booth) has PRE filters, medium filters and HEPA filters to keep air cleanliness of work area.
