Safe and Accurate Powder Weighing – Free White Paper


Ideal for user protection during precision weighing tasks

Designed specifically for powder containment applications, the Captair Smart filtering weighing station delivers the proper airflow at the face of the enclosure and total filtration of hazardous powders or potent compounds. The enclosure is designed to allow full access to your balance and reduce airflow turbulence to maintain stability to 6 decimal places without compromising containment.

The air exhausted into the room complies with Class 5 (E.N. ISO 14 644) standards.


Advanced Filtration will keep you safe

Featuring HEPA H14 filters comply with the EN 1822-1 standard to provide an ISO Class 5 work environment and provides 99.995% filtration efficiency for particles larger than 0.1µm. For even greater efficiency, choose an ULPA U16 filter to provide an ISO Class 5 work environment which provides 99.9995% filtration efficiency for particles larger than 0.1µm according to the MPPS method set forth in the EN 1822-1 standard.

When performing applications using hazardous chemicals, add our BE+ molecular filter that can absorb multiple chemical types at the same time.


Investment and energy savings

  • No ducting to the building ventilation system
  • Eliminates the energy consumption linked to the air renewal (air supply/extraction, filtration, dehumidification, air conditioning)
  • Very low running cost: energy consumption from 70W to 191W


  • No ductwork necessary, quickly set up on a bench or with a rolling cart
  • Easy to relocate
  • Protect the environment with o direct emission of pollutants into the atmosphere


Smart technology

Each unit comes with Smart TechnologyTM – an exclusive set of tools that is comprised of smart-light communicationTM, chemical sensors, real-time status, and the eGuard app.

Smart-light communication is a soft band of light on the unit that lets you know the unit is operating safely. The band of light will slowly pulse to let you know if the airflow is compromised, if there is a fan failure, or there it is time to change your filters.
