  • 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.
  • 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 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.
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 with PC-CRC/electro galvanized steel or stainless steel (SS-304)
Front Window/Sash
  • Counterbalanced front window/Sash having laminated U.V. protected toughned safety glass with front closure panel and specially extruded anodized aluminium frame. In addition it serves optimum resistance and protection from harmful UV rays, protection user from exposure to harmful Ultraviolet radiation.
  • Equipped with Microprocessor controller having alphanumeric display and soft touch controls. Controller indicates all input, status, alarm function and control for blower, lights outlet and UV.
  • Continuous monitoring through bright easy to read LCD panel
  • Password Protection for authorized operation.
  • Real time Clock
  • UV timer showing used time and balance available life in hours.
  • Total HEPA Filter time showing used time and balance available life in hours.
  • HEPA filter choke alarm after HEPA filter life is over.
  • Display of safe/unsafe position of door.
  • Audio Visual door unsafe alarm, if door is at incorrect operating height.
  • UV light/Door/Fluorescent Light Inter Lock, i.e. UV switches ON only When door is closed, and automatically switches OFF fluorescent lights.
  • If UV light is on & the operator tries to open the door, it raises audio visual alarm.
  • Intelligent microcontroller based monitors airflow in real-time Via temperature compensated sensors and conserves UV lamp life with unique timer function.
  • Built-in RFI and electrical noise filters eliminate interference with adjacent instrumentation.
  • All electronic parts are contained inside a plug-and-play module that permits easy exchange if required.
  • Automatic start-up sequence will prepare the cabinet for normal operation and advise when safe conditions are established.
  • An administrate controlled PIN (Personal Identification Number) can be set to restrict access to main menu.
  • The airflow alarm can be activated or deactivated depending on user preference and nature of the work.
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 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.
Digital Downflow Velocity Indicator and Transducer (OPTION)
  • Monitors real-time downflow velocity and display results on the panel.
Hour Meter
  • It monitors the total usage time of UV lamp and helps in estimation for the need of lamp replacement.
Electronic Filter Choke Alarm
  • An electronic differential pressure monitor sounds an audio alarm at a preset value at choke position, helping user to plan for filter replacement.
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 CRC tubular pipe duly powder coated and fitted with durable castor wheels for rotation and total brake system on front wheels. However for tubular stand made of stainless steel (SS-304), in lieu of powder coated CRC tubular pipe, are also available at extra cost on request.
