Purair BIO Biological Safety Cabinets

  • Safe. NSF 49, EN 12469, and UL61010-1 certified, ensuring safe operations for operators, the environment, and products. An “EN certified only” model, the Purair BIO-EN, is also available.
  • Double-wall cabinet design. Contaminated air is fully contained and isolated thanks to a double-wall cabinet design and negative internal pressure.
  • No safety dead zone. The Purair BIO has an innovative surrounded air intake grille that keeps all contaminated air contained within the cabinet.
  • HEPA Filtration. The AstroCel® supply/exhaust HEPA filters provide 99.995% efficiency at 0.3 microns (Class H14).
  • Isolated Controls. All control systems and pipelines are completely isolated from contaminated areas for safe and convenient operations. APPLICATIONS The Purair® BIO is designed for applications that involve low and moderate risk biological agents. Specific applications include, but are not limited to: • Life Science Research • Sterile Product Preparation • Biological Protocols
  • Purair BIO (PB-48), shown with optional stand with leveling feet.



A. User Interface: Ergonomics, safety and aesthetics all come together with the 10º pitch of the face.

B. Removable Tray: Raised one-piece work surface lifts and removes for easy surface decontamination.

C. Durable Interior: The Purair BIO utilizes a heavy-gauge, one-piece liner with coved corners for easy cleaning and durability.

D. Standard Control System: Reliable rocker switches and easy-to-read gauge for safety and durability. EN-only models are equipped with membrane-style switches.

E. Double-wall Plenum Design: Double-wall design creates a unique plenum which surrounds contaminated areas with negative pressure, preventing the possibility of contamination from leaks in filter seal, gasket or cabinet structure.

F. Ergonomic Fit: The angled front, narrow-front grille, raised armrest and frameless sash create an ergonomic work environment. Unique front grille designed to provide the maximum product and personnel protection.

G. Clean: Single-piece stainless-steel work tray and front grille, lower drain pan with angled side, and single-piece work zone liner eliminate joints for superior cleanability.

H. Safe: HEPA filters (Class H14) tested to a typical efficiency of >99.99% for 0.3 micron particles.

I. Robust Cabinet Construction: Key components, including fluorescent lamps, motor capacitor, electrical harness, electronic ballast, and switch control are mounted outside the airstream and away from contaminated air to permit service without decontamination.

J. Surround Air Intake Grill: All contaminated air is enclosed in the work area. No safety dead zone.

K. Optional Mounting Stand: Stand height of 26″ (660 mm) creates work surface height of 29.4″ (746 mm) for seated position. To configure height for standing position, contact Air Science.


NSF 49 & EN12469 Listed: Certified for safety and performance. NSF 49 and EN 12469 certified to meet international and industry standards of performance and protection.

Safety Interlock Feature: Activates the fan and fluorescent light in the cabinet automatically when the sash window is opened. The UV light is also automatically switched off during this time. When the window is fully closed, the UV light is switched on and the fluorescent lamp and fan are turned off automatically.

Standards Compliant: The Purair BIO undergoes 10 internal quality tests prior to leaving the factory, including pressure decay testing, downflow velocity testing and HEPA filter leak testing.

Full Product Support: The best value Class II Biological Safety Cabinet on the North American market supported by nationwide sales and service representatives.
