Purair FLEX Portable Isolators

Purair Flex polyurethane glove bags

The Purair ® FLEX is a revolutionary containment product that redefines when and where glove bags can be used. Designed as a flexible, highly portable film isolator, the Purair FLEX permits easy set up and delivers superior containment capability.

The Purair FLEX is constructed of ArmorFlex ® film which offers complete visual clarity and excellent solvent resistance across a range of chemicals as confirmed by independent product testing.


Purair FLEX Features and Benefits

  • Compliant with Multiple Criteria. ArmorFlex film complies with FDA 21CFR and 2002/72/EC standards for minimal outgassing, solvent and biological reactivity and static resistance.
  • Pharmaceutical Grade Materials. The Purair FLEX is constructed with FDA approved pharmaceutical grade LLDPE1 anti-static and ESD2 safe and meets European ATEX Directive.
  • Large Workspace. At 30" (762 mm) wide and an internal volume of 3 cu.ft. (85 L) the Purair FLEX provides a large work area with a 12.5" (317 mm) gas tight zippered access with a 6" (152 mm) diameter opening.
  • Oxygen-free Work Zone. A nitrogen gas barb is a standard feature to permit creation of an oxygen-free workspace.
Air Science provides containment solutions to meet any analytical need. The Purair FLEX glove bag provides numerous performance advantages over the competition:
  • Purair Flex portable isolator Brochure Spacious Interior Volume. An innovative curved film design provides maximum working volume and visibility.
  • Easy Setup. Semi-rigid support rods simplify set up and increased stability even if the bag is not inflated to full pressure.
  • Bag-In/Bag-Out Safety. Additional HEPA filter, Bag-in/Bag-out Port, and Nitrogen purge inlet connections enhance safety to meet specific needs.


Bag-In/Bag-Out Port

  • A 7" (200 mm) diameter bag-in/bag-out minimizes exposure to contaminants when changing the filter. The contaminated filter is safely removed through the port and placed into a bag, sealed with a reuseable cable tie, and disposed. A new bag is affixed to the port when the replacement filter is installed.
