Controlled With Single
or Double Fan
Foreword
BSC-EN 2000 safety cabinets belong to the
latest generation of laminar airflow
systems, combining rigid safety requirements with high quality
construction.
BSC-EN 2000 has been designed as a Class II Biohazard cabinet
according to EN-12469.
Therefore it provides vertical laminar airflow with part of the
air recirculated via the main HEPA filter whilst the remaining
part is discharged through an exhaust HEPA filter. This cabinet is
suitable for handling CDC 1-3, DPAG C-B1-B2 etiologic agents,
providing operator, product and environmental protection
Applications
BSC-EN 2000 cabinets can be used in a
wide range of disciplines, as defined in appropriate standards.
Especially suitable for applications such as:
Benefits
-
Sophisticated microprocessor based monitoring system
-
Sophisticated microprocessor based system of audible and
visual alarms alerts the operator if the cabinet does not
operate in complete safety.
-
Self-adjusting system to ensure a constant laminar airflow
speed even in the presence of a progressive clogging of the
filters.
-
The negative pressure plenum "bio-dynamic sealing"
ensures that all contaminated particles are kept inside the
system and are automatically drawn to the pressure chamber to
be captured and by the main and exhaust filters.
-
The fan system assures that no part of the cabinet is under
positive contaminated pressure to the laboratory, thus
preserving environment and personnel from bio-contamination
risks.
-
Access from the front panel for ease of maintenance service.
-
Available in one
motor (BSC-EN 2000 S) as well as two motors (BSC-EN 2000 D)
versions for flexible performance selection in line with the
cabinet's use.
Specifications
Construction:
Epoxy powder painted steel for improved strength and resistance to
corrosion and atmospheric agents.
Work Surface : AISI-316 stainless
steel completely perforated to ensure flow laminarity and air
recycling at the work surface level. Frontal slots in the access
area provide air barrier protection preventing any exchange of air
between the inside of the cabinet and the environment.
On request the following work surfaces are available:
-
AISI-316 stainless steel perforated work surface in 3, 4, or
6 pieces
-
AISI-316 stainless steel solid work surface in 1,3, 4, or 6
pieces
Work Chamber: in AISI-304
stainless steel sheet.
Absolute Filter : HEPA filters,
tested with D.O.P. aerosol. Their efficiency, higher than
99,995%MPPS - 0.005% penetration - ensures a performance exceeding
the requirements ofEN 1822, U.S. Federal Standard 209 e, British
Standard 5295, VDI-2083 and AS 1386-1976.
The filtration system is designed to provide a barrier of air with
minimum average speed over 0.4m/sec. according to EN-12469.
Motor-blower/s: One centrifugal
fan (BH-EN 2000 S) and two centrifugal fans (BH-EN 2000 D), direct
driven motors, with protection factor IP-55, controlled by two
automatic speed regulators and microprocessor system showing
laminar flow and protection barrier work conditions.
Microprocessor based monitoring system:
new generation system for controlling the cabinet in a full
digital way performs high level control and data processing.
The handy and practical keyboard and the rearlit LCD display keep
the user constantly informed of the cabinet conditions and
operation, in particular:
-
display of laminar airflow velocity and frontal air barrier
velocity
-
display of inside and outside temperature
-
display of residual lifetime of HEPA filters, U.V. Lamp and
charcoal filter (if installed)
-
display of total time of cabinet operation
-
display of power rating factor of the main and exhaust (if
installed) motor-blowers.
Alarms for:
-
out of range laminar airflow velocity and front air barrier
velocity
-
front window opened.
-
HEPA filters clogging
-
UV lamp worn-out (if installed)
-
charcoal filter (if installed) saturated
-
blackout
-
signal of other possible malfunctions and relevant remedies.
Power Supply : 230V,
50Hz, single phase.
Lighting: fluorescent tubes in
built-in housing, placed outside the contaminated area.
Front window :
Stratified safety glass, to give ease of access for large items.
It is provided with gas spring to keep it open during maintenance
or sanitization operations.
Additional Features:
-
two vacuum or gas connections in the working area are
provided, one with manual tap, the other with solenoid valve
(on the right-hand side).
-
A stainless steel spillage tray beneath the work surface
collects spilt liquids.
-
A stainless steel front closure panel ensures the sealing of
the cabinet for sterilization/fumigation .
-
An inlet allows the DOP test of the absolute HEPA filters.
-
Electrical socket with protection IP-44 (on the right-hand
side)
-
Maintenance: access to filters, motor-blower/s and control
panel by lifting the front panel.
As Option:
-
UV lamp for sterilization of the
work chamber installed onthe front closure, controlled by two
timers, one with 0¸3 hours scale
(1 minute steps), the other 3 fixed hours.
