Purair BIO Biosafety Cabinets

Class II Biological Safety Cabinets

20% OFF list price for our Summer Sale! On now until July 31, 2024!

The Purair® BIO BSC is designed to protect individuals, the environment, and products from a variety of biological particulates, serving as the primary barrier in life science research and experimentation.

As a Class II Type A2 biosafety cabinet, the Purair BIO minimizes and contains Biosafety Level 1-3 agents, maintaining negative pressure inside the cabinet during operation to prevent contaminants from escaping the work area. HEPA filtration scours 70% of the incoming room air to protect the products, while the remaining 30% of the exhausted air is filtered by a second HEPA filter. Purair BIO cabinets provide ample workspace with environmentally sound operation and low energy consumption.

Purair BIO Features & Benefits

The Purair BIO saves money and decreases the load required on your facility HVAC system. Industry-leading innovations and technology make the Purair BIO:

  • Easy to Install. The biosafety cabinet is self-contained and does not require venting to the outside. Units are portable and may be moved from one location to the next with minimal downtime and without filter changes. Set-up, operation and filter maintenance are straightforward.
  • Energy Efficient. Because filtered air is returned to the room no demands are required of the facility HVAC capacity for make-up air.
  • Cost Effective. Facility ductwork, HVAC and construction costs are eliminated.
  • Safe to Use. Cabinet airflow and face velocity protect users from incidental exposure to particulates.

HEPA Filtration

HEPA filtration protects the operator from particulates and the process/samples from contamination by maintaining cleanliness within the work zone.

Green class II Safety Cabinet airflowThe Purair BIO uses AstroCel® HEPA filters to provide a range of high performance protection. These self-contained filters are designed to physically capture particles larger than 0.3 microns with >99.995% typical efficiency.

The AstroCel II Fluid Seal filters feature an integral groove filled with gel at the air inlet side, ensuring a perfect seal to the housing system. The aluminum frame guards against swelling typical of wooden framed filters. The filters do not contain aluminum separators to provide unobstructed airflow and superior filtration.

A patented HEPA filtration lock maintains filter efficiency, minimizes the chance of leakage and prolongs filter life. The filters can also be changed from the front side of the cabinet quickly and easily.

Energy Efficient Protection

The Purair BIO maintains the world's highest ECM rating for a brushless DC motor and saves up to 86% over traditional PSC motors (based on internal testing). Additional benefits include:
  • Extended filter life. Constant airflow design automatically adjusts air pressure to stabilize airflow and extend the life of the installed HEPA filters.
  • More Air Volume. High torque capabilities transport more air volume and pressure than traditional AC motors.
  • Energy Efficient. Over 80% of the output power is converted to kinetic energy to ensure ongoing energy savings over the life of the motor.

Electrical Safety and Certification

  • All components meet or exceed applicable safety requirements.
  • Each cabinet is individually tested for electrical safety at the factory and documentation specific to each tested cabinet is maintained on file.
  • UL Listed for USA and Canada.
  • Models available with NSF 49 and EN12469 certifications.
Contact Air Science or your Sales Rep for preparation information.


The Purair BIO and BIO-EN cabinets are warranted for 5 years for cabinet structure, 1 year for electrical components, and 1 year for all consumables.

Each cabinet is shipped with a comprehensive user manual and IQ/ OQ documentation is available upon request.

Product Features:

Biological safety cabinet class 2 features
Purair® Bio PB-48, shown with optional base stand with adjustable 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.

Other Features:

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.

NSF Certification applies to the biological safety cabinet Models AHA-143-BA-A (Air Science Model PB-48-R-115, 115V, 60Hz) and AHA-143-BB-A (Air Science Model PB-48-R-230, 230V, 50Hz), and Models AHA-143-AA-A (Air Science Model PB48-M-115, 115V, 60Hz) and AHA-143-AB-A (Air Science Model PB-48-M-230, 230V, 50Hz) manufactured by Chung Fu Technical Development Co. Ltd., Taipei, Taiwan, and marketed by Air Science, LLC, USA.

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.
