Air Science Purair BIO Biological Safety Cabinets with NSF Standard 49 Certification

Why is NSF Certification Important?

The NSF seal indicates the Purair BIO BSC has undergone extensive, third-party testing that has verified compliance with important national and international safety standards and regulations.i

The Purair BIO BSC is suitable for working with biosafety agents at levels 1, 2 and 3. The combination of HEPA supply and exhaust filters yields a fully integrated performance envelope for product, personnel and environmental protection from particulates. The Purair BIO BSC simplifies operation and user interface while essential functions are maintained. It offers a cost-effective, efficient and compliant solution to biological safety cabinet applications in life science and associated uses.

Benefits of New NSF-Certified Biological Safety Cabinets:

  • Improved Efficiency – A single blower motor reduces energy consumption by more than 80% compared to traditional motors, with no compromise to performance. These energy savings accelerate ROI, especially where multiple cabinets are used.
  • Contamination Control – VIRO-CUT™ Antibacterial Stainless Steel, which provides latent passive contamination control against most airborne contaminants.
  • Versatility – Compact, slim-profile designs make installing and relocating Purair BIO biosafety cabinets easier.
