Are your weighing processes safe?

The Purair® RX Balance Enclosure is designed with ductless technology to keep you safe from powders or particulates during the weighing process. The Class I enclosure meets USP 800 requirements. It comes in three sizes and offers two depth choices for benchtop or freestanding installation.

The innovative design of the Purair RX prevents by-pass leakage, monitors airflow, and uses the Multiplex™ Filtration System, with a pre-filter, HEPA filter, and secondary HEPA or carbon filter, to keep you safe.

We understand the high risks associated with handling pure pharmaceutical powders. Choose your equipment wisely. Don’t let your safety hang in the balance.

At a Glance:

  • Safer Environment. The Purair RX uses Multiplex Filtration to contain particulates. The ductless design prevents the release of these contaminants to your work or ecological environment.
  • More Versatility. The factory-installed exhaust canopy allows for thimble ducting to the outside. Portability of the unit also means you can move it wherever you need it most.
  • Safer Filter Replacement. The optional Air Science® SafeSwitch™ bag-in/bag-out filter replacement system minimizes exposure to filter contaminants when removing used filters and inserting replacements.

In addition to the Purair RX, Air Science offers a full range of equipment for pharmaceutical research laboratories. Our cabinets, enclosures, and stations are built to deliver time-tested performance, low operating costs, and proven containment.
