Introduction
The Purair BIO 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 Controller
The Purair BIO includes an integrated control center for easy management of all functions.
Analog Minihelic gauge verifies airflow; On/Off switches are provided for interior lighting, UV lamp, interior outlet activation and fan; Sash alarm indicator activates an audible and visual warning of unsafe sash position (8 inches or 20cm from the bottom of cabinet); Mute button silences the alarm for a specified time; On/Off switch controls main power.
PURAIR® BIO AIRFLOW PATTERN
Containment and Protection
The Purair BIO maintains an airflow ratio of 70% recirculation to 30% exhaust to ensure operator protection. The inflow and downflow balance is precisely established, with no room air entering the work zone to prevent product contamination.
Airflow patterns are precisely tuned and tested to create an optimum air curtain on the front aperture, maintaining personnel and product protection even during the unlikely event of severe inflow or downflow imbalances.
The integrated HEPA filtration system provides clean air to the work surface in a gentle vertical laminar flow pattern, allowing the exhaust HEPA filter to trap biohazardous particles prior to the air being exhausted into the room.
HEPA Filtration
HEPA filtration protects the operator from particulates and the process/samples from contamination by maintaining cleanliness within the work zone.
The 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.
Purair® BIO Features and Benefits
