Features

• 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. The prefilter fitted extends the life of HEPA filter drastically. Fitted with HEPA Filter made from water resistant, fire retardant, imported micro fine glass fibre media; conforms to EU – 14 Grade, with an efficiency rating better than 99.999% for 0.3 μ.These filters are designed to accommodate higher air flow volume.
• Prefilter are made from Non-Woven Synthetic with HDPE mesh and Al expanded mesh on air leaving side; conforms to EU – 4 / G-4 Grade, with an efficiency of down to 10 micron. These filters can be cleaned by compressed air & also washable.
• Mounted on heavy tubular stand with lockable castors.
• Aerodynamic airflow grills maintain safety and prevent 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.
• The sash is counterbalanced for smooth and lightweight operation with the standard opening of 200mm ±10 mm for easier access to work zone and enhanced user safety.

Cass II Biosafety Cabinet Protection

• 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.

Cass II Biosafety Cabinet Key Features

• 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.

Cass II Biosafety Cabinet Applications

• 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 : Type A2
• Protection From Particulates : Personnel, Work Area (Product) and Environment
• From Vapors and Gases : 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

Working Table is made up of Stainless Steel (SS-304). External Cabinet is fabricated of CRC sheet duly powder coated OR Stainless Steel (SS-304) (as ordered).

Front Window/Sash

Front Sash consists of a toughened transparent glass 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.

Controller

These models are provided with TFT Touch Screen Display Controller with air velocity sensor.

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

Floor Stand is made up of heavy duty tubular pipe duly powder coated and provided with leveler.
