During the weighing and packaging of dust and reagents, a negative pressure weighing room ensures controlled containment, preventing airborne particles from escaping. This system helps protect personnel from inhaling harmful substances while eliminating cross-contamination, safeguarding both the indoor environment and external surroundings.
Structural Composition
The negative pressure weighing room consists of several integrated components, including:
- Working area
- Return air box
- Fan box
- Air outlet box
- Outer enclosure
- Filtration system: Initial effect filter, medium effect filter, and high-efficiency filter
- Variable air volume air unit
- PLC control system and sensing system
