Negative Pressure Weighing Booth (Sampling Booth/Dispensing Booth)

The negative pressure weighing booth is a kind of purification equipment, its pressure in working area is lower than outside. It is mainly used for weighing materials such as drugs or activated carbon, and four levels of protection in the process of sub-packaging: materials are protected from pollution by personnel and environment, the environment is protected from pollution by materials and dust, and operators are protected from pollution by materials and dusts. Its air flow pattern and pressure of the environment are not affected by on or off state of weighing booth. The equipment is widely used for weighing and sub-packaging in pharmaceutical, medicine and health and environmental protection.

1. Main Characteristics:

  • There are pockets and containers for collecting materials under negative pressure room.
  • An isolation plate is installed on operating area to ensure that material will not fly out of the operating area.
  • A flow equalizing plate makes wind speed uniform and ensures that wind speed on the same plane is consistent.
  • Automatic control of air supply and exhaust to ensure that operating area is in a state of negative micro-pressure relative to the outside of equipment.
  • Automatically controlled by microcomputer and wind speed is automatically constant.
  • The operating parameters of equipment can be stored and printed. If operating parameters exceed the set limit, the equipment will alarm.
  • Negative pressure weighing booth can be made as follows: movable type, integral type, assembled type.
