Class II Biohazard Safety

Class II Biohazard Safety cabinet should provide personnel, product & environment protection.

Class II Cabinets differ in proportion as 70% air is re-circulated within the cabinet through ultra low particulate air (HEPA/ULPA) filtration. Velocity of airflow to the work zone creates an class 100 environment for product protection, where the remaining exhaust air is discharged out through HEPA/ULPA).

Air barrier at the work opening & the contaminated air plenum under positive pressure. An air barrier between the operator & the work zone maintained by a flow of room air through a full width grille in the work opening.

Features

• HEPA /ULPA filters tested to a typical efficiency of 99.997% up to 0.3 micron for better contamination free condition.
• Washable Non woven synthetic polyester pre filter traps large particles protecting main filter & thus increasing the life of main filter.
• Seamless stainless steel removable work surface.
• The cabinet designed with curved frond edge for maximum operator comfort.
• The closing/opening of front door is integrated with the UV ON/OFF. The UV will automatically switch “OFF” when the sash door is opened & switch “ON” when door is closed to avoid accidental exposure of UV light to the operator.
• Electrical components used are standard for better electrical safety for the operator.
• Double inlet blower fitted in such a way to reduces vibration.
• UV absorbent counterbalanced front sash door made up of toughened glass or polycarbonate sheet provided with channel locks for adjustment at particular level.

Technical Specification

• Cabinet Provides the Product, Person and Environmental protection
• Class II Biohazard Safety cabinet should provide personnel, product & environment protection.
• Class II Cabinets differ in proportion as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA/ULPA) filtration.
• Velocity of airflow to the work zone creates a class 100 environment for product protection, where the remaining exhaust air is discharged out through (HEPA/ULPA)
• Air barrier at the work opening & the contaminated air plenum under positive pressure
• The barrier air mixes with the laminar flow air in a sump underneath the work surface & is exhausted to the outside environment through a HEPA/ULPA filter.

Filter Type

• HEPA/ULPA filter with internal metal guards & frame gaskets.
• Supply of HEPA/ULPA filter with efficiency of >99.999% at 0.1 to 0.3 micron

Front Sash Door

• Manual sliding sash door made up of imported poly carbonate sheet or toughened glass with sloping front for better access of samples
• Front sash door height can be easily adjusted as per required by end-user.
• The transparent sash door maximizes light & visibility inside the cabinet, providing a bright & open working environment.

LCD Display

• Digital Microprocessor Control System for Operating Fluorescent, UV Light & Blower.
• Continuously display true value of differential pressure of HEPA/ULPA filter for inflow as well as down flow velocity.
• Conveniently located display on outside of the Biosafety Cabinet for easy use & also easy to reach from a seated working position

Blower-Motor Assembly

• Dynamically & statistically balanced aluminum centrifugal impeller driven by single phase, 2800 RPM motor
• Double inlet blower fitted in such a way to reduces vibration & noise.
• Blower is positioned in such a way that, to create an even filter loading, it helps to prolong the life of HEPA/ULPA filters.
• Provide uniform airflow by adjusting working voltage of fan
