Biological Safety Cabinet (Type A-2) MSW-164 A2

  • 30 % air exhaust
  • 70 % air recirculation
  • HEPA-filtered exhaust air in Type A2 cabinet may be recirculated into the room or exhausted to the outdoors through a canopy exhaust connection.
  • HEPA-filtered downflow air is a portion of mixed downflow and inflow air from a common plenum
  • Negative Pressure air surrounding all biological contaminated ducts and plenums.
  • Negative pressure surrounds the work area with double wall plenums for protection.
  • Air drawn through pre-filter is made to pass through highly effective HEPA (High Efficiency Particular Air) filters having efficiency rating as high as 99.99% with cold DOP and 99.97% with hot DOP, thus retaining all air-borne particles of size 0.3 micron and large. The highly efficient HEPA filter maintains the optimum cleanliness and purity. Being equipped with the prefilter, it can extend the life of HEPA filter.
  • Aerodynamic airflow grills maintain safety and prevents blockage.
  • U.V and fluorescent interlock available
  • Ergonomic and comfortable 10 degrees sloped front window for comfortable head and elbow rest position, thus reducing fatigue
  • Sash is counterbalanced for smooth and light weight operation with standard opening of 200mm ±10 mm for easier access to work zone and enhanced user safety.
  • Personnel protection from harmful agents used inside the biosafety cabinet.
  • Product protection to avoid contamination of the works, experiment or process from outside contaminants.
  • Environmental protection from contamination of the works, experiment or process from outside contaminants.
  • A front access opening with careful maintained inward air flow.
  • HEPA-filtered, vertical, unidirectional airflow within the work area.
  • HEPA-filtered exhaust air to the room or exhaust to a facility exhaust system.
  • Type A2 cabinets are typically used for biosafety levels 1 through 3 and are suitable for work with chemicals, as long as vapors are not hazardous and will not interfere with the work when recirculated, it is acceptable to use an A2 cabinet with a small amount of chemicals when the cabinet is exhausted to the outdoor (Option) for removal of gases.
Class - II Protection From Particulates From Vapors and Gases
Type A2 Personnel, Work Area (Product) and Environment If exhausted to room : not for use with vapors and gases
 If exhausted to facility exhaust system, protects personnel
    If exhausted to a treated facility (VIRUS BRUN OUT) exhaust System protects personnel, the work area and the environment.

Upper & Front Cover
  • Removable upper and front cover simplifies filter, blower and front control panel replacements and maintenance easier.
Material of Construction
  • Internal Working Chamber is made up of Stainless Steel (SS-304).
  • External Cabinet is fabricated of Cold Rolled Steel Duly powder Coated.
Front Window/Sash
  • Front Sash consists of a thick plexi-glass or toughened transparent glass (Option) for a clear inside view. In addition it serves optimum resistance and protection from harmful UV rays, protection user from exposure to harmful Ultraviolet radiation.
Drain Trough with Valve
  • The trough at base is easy to clean and for offloading liquid spillage if any.
Decontamination by UV Lamp
  • UV Lamp to produce UV rays of 253.7 nanometers and fluorescent lamp are interlocked and motor blower are turned off/on as and when front sash is closed/opened. UV lamps functions through a timer (Option) to control the decontamination cycle and maximize UV lamp life. The UV lamp shuts off once the desired set time of decontamination is over and switches the fluorescent lamp to ON position.
Splash Proof Electric Supply Socket
  • Splash proof sockets is provided for optimum convenience of using small electrical devices inside the cabinet.
Front Airflow Intake Grid
  • Aerodynamically designed front airflow intake grid eliminates potential turbulence and contamination.
Floor Stand and Castor Wheels
  • Floor Stand is made up of heavy duty tubular pipe duly powder coated and fitted with durable castor wheels for rotation and total brake system on front wheels.
