■ Introduction
The Envirco Biological Safety Cabinet provides product,
personnel and environmental protection and verifies
cabinet integrity and performance. It is suitable for Biosafety
Levels 1, 2 and 3 per CDC/NIH and NCR criteria. Preparation
of chemotherapeutic drugs may also be performed in the
Envirco Biohazard Cabinet per OSHA requirements. In addition,
the cabinet provides an engineering control per the OSHA
Bloodborne Pathogen Standard.
■ Airflow System
»» 70% air recirculation.
»» 30% air exhaust.
The unit maintains a minimum average inflow velocity of 0.65
m/s and average downflow velocity of 0.37 m/s.
■ Product Features
»» Advanced Microprocessor Control System: This control
system measures the air flow pressure accurately, strictly
balancing the air velocity for entire working chamber. A
unique advanced feature is an indicator bar on the LED
control panel that is as an indicator for the life main filter and
exhaust filter. This indicator will remind the user to replace
the HEPA filters on time and will provide additional protection
for the operator and environment.
»» Intelligent Filter Compensation System: The vertical
airflow will be automatically supplied at the speed of 0.37m/s
± 0.015m/s without interruption. When filter block occurs, the
fan motor will increase its speed to ensure constant vertical
air flow to guarantee the safe performance.
»» HEPA Filter. 99.998% Efficient (0.3 microns), constructed of
pleated borosilicate glass fibers.
»» The motor driven front window can be moved smoothly and
exactly to a desired position, and it can be completely closed
when not use, providing a physical barrier.
»» Easy to Decontaminate and Disinfect: The working
chamber of the safety cabinet can easily be cleaned and
disinfected. The stainless steel counter surface can be
removed for autoclaving. The UV light can only be turned
on when the front window is closed completely and the
fluorescent lamp is turned off. It avoids the potential hazard
to the operator from UV light.

Features & Benefits
■ Performance Features
■ Safety Features
»» HEPA Filter (Standard for Manual Window Series) 99.998%
efficient (0.3 microns) HEPA filter is constructed of borosilicate
glass fibers.
»» Filter Life Indicator: The pressure is displayed on the control
panel to show the life of the main filter and exhaust filter.
»» A microprocessor control system with LED display makes it
clear for all control and safety functions.
»» True airflow velocity (both down-flow and inflow) sensing
technology, with temperature compensation for improved
sensor accuracy. The velocity value shows continuous digital
display on the front LED control panel for constant monitoring.
»» UV timer function to control the decontamination cycle and
maximize lamp life.
»» Easy to decontaminate and disinfect. The working chamber
of the safety cabinet is easy to be cleaned and disinfected.
The stainless steel counter surface can be removed for
autoclaving.
»» Weight-balanced front window.
»» Cabinet Leak Test: Cabinets have to pass pressure decay
test as defined in the US Stand ANSI/NSF 49:2002.
»» KI-Discus Containment Test: Cabinets are tested using the
KI-Discus method for containment and operator safety at the
manufacturing site.
»» Filter Leak Test: Cabinets are tested using an aerosol
photometer according to US Standard ANSI/NSF 49:2002.
This test determines the integrity of down-flow and exhaust
filters, filter housings and filter mounting frames.
»» Automatic self-filtering cycle at start-up requires a fixed period
of warm-up period during which the cabinet work zone is
purged of contaminants before use.
»» Intrinsically-safe negative pressure design.
»» The motor/blower system is able to compensate automatically
to maintain the down-flow air at the speed of 0.37±0.015
without interruption to guarantee the safe performance.
»» Interlocked UV light only operates when blower and
fluorescent light are off and sash is closed.
»» Front window glass (standard) or non-reflecting multilayer safety glass (optional), which provides enhanced UV
protection for operators.
»» Audible and visual alarms prompt the operator in case of any
unsafe condition.
■ Ergonomic Features
»» 10° Sloped front enhanced mobility and depth of reach into
the work area, also provides maximum protection.
»» Control panel is sloped downwards to provide the operator
(in a setting position) a better view of and an easier access to
the controls.
»» Inclined, sliding sash.
