Zhongjing GMP SS304 negative pressure weighing booth for customized pharmaceutical lab
The negative pressure weighing booth as specialized containment system is designed to protect operators and the environment from exposure to hazardous powders (e.g., APIs, cytotoxic drugs) while maintaining product integrity.
Controlled inward airflow is generated by an exhaust fan, creating a negative pressure zone inside the booth.
Airflow velocity ensures that any airborne particles are drawn away from the operator and into the filtration system.
Clean air is supplied vertically downward through HEPA H14 filters, creating a particle-free workspace for weighing.
Unidirectional laminar airflow minimizes turbulence and cross-contamination.
Escaped particles are immediately captured by the inward airflow and directed toward the booth's exhaust system.
Redundant exhaust HEPA filters trap hazardous particles before air is safely discharged.
Differential pressure sensors continuously monitor containment performance. Audible/visual alarms alert operators if pressure deviates from setpoints.
Stainless steel surfaces allow wipe-down with solvents (e.g., ethanol, VHP-compatible).
Pharmaceutical-Grade Stainless Steel Construction
304/316L stainless steel interior and exterior surfaces for superior corrosion resistance, cleanability, and compliance with GMP and ISO requirements.
Electropolished finishes (Ra ≤0.5μm) to minimize particle adhesion and microbial growth.
Negative Pressure Containment System
Controlled airflow (typically 0.45-0.55 m/s) ensures inward directional airflow to protect operators from exposure to hazardous powders.
Differential pressure monitoring with alarms to maintain safe containment.
HEPA Filtration
Downflow HEPA H14 filtered air provides ISO 5 (Class 100) cleanliness for the weighing zone.
Redundant exhaust HEPA filters to capture escaped particles before air is discharged (optionally connected to facility exhaust).
Ergonomic & Safe Design
Smooth, radiused corners and sloped surfaces for easy cleaning and no particle accumulation.
Anti-static work surface (optional) to prevent powder static buildup.
LED lighting (integrated or external) with shadowless illumination for precision work.
Advanced Control System
Touchscreen for real-time monitoring of:
Airflow velocity
Differential pressure
Filter status (pressure drop alarms)
