The Weighing booth, also known as negative pressure booth 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.

• Automatic changeable frequency system monitors the air velocity to ensure its stability in the work area.
• Differential pressure gauge is equipped to real-time monitor the filters.
• Unique designed air duct effectively controls the noise.
• Uniform flow design of main working area can protects the operators and prevent environmental pollution and cross contamination of products.
• Intelligent control mode and alarm system ensure the reliability of running.
• Smooth transitions of wall and ground can eliminate the blind angle.

This instrument is applied for pharmaceutical, microbiological, scientific experiments, food industries and hospital operating rooms.
