SAFEFAST ELITE CLASS II B2
Applications
SafeFAST Elite Class II B2 have been adopted worldwide in use for product, personnel and environmental protection while handling harmful agents pathogenic to human beings and/or animals as defined in the appropriate international standards.
SafeFAST Elite Class II B2 is commonly used in laboratory to handle volatile toxic chemicals and radionuclides required as adjuncts to a wide range of disciplines in applications such as: Microbiology, Virology, Haematology, Cell culture, Genetics, Handling of hazardous agents to human beings or animals.
Operational Principles
The Air from the external environment is sucked by means of the motor blower and pre-filtered by means of a G3 pre-filter positioned on top of the unit. Air is then pushed through the main H14 HEPA-ULPA filter which delivers air clean in class ISO 3 as per ISO 14644-1 and Laminar Flow conditions in the work chamber.
Air from the front aperture passes under the work surface through the slots positioned on the edge of the work surface and is filtered by the second H14 HEPA-ULPA filter which works as the exhaust filter.
This air is then mixed together with the air from the chamber and passes in the exhaust channel positioned in the back of the chamber before being exhausted.
100% of air is finally exhausted outside thanks to the push of the second motor blower.
Specifications
External structure in epoxy powder coated cold-rolled steel for excellent corrosion resistance to the attack by aggressive common chemicals. Alternatively special models with external structure made in AISI 304L stainless steel for superior cleanability are also available on demand.
Rear wall in stainless steel AISI 304 L, designed to conform to requirements and pass the “cleanability test” according to EN12469:2000.
Work surface in stainless steel AISI 316L as standard supplied with spill retaining solid work surface (perforated upon request) which is easily removable for carrying out routine cleaning and/or autoclaving sterilization procedures. Special sloping profile below work surface to ease H14 HEPA/ULPA filter replacement and spilled liquids collection.
Front window: electrically operated vertically sliding safety glass sash window.
System of two motor fans: the units are supplied with double motor-fan in order to discharge the total volume of treated filtered air outside the laboratory through a ducting system.
Filtration: H14 HEPA/ULPA filters with an efficiency better than 99,995 % MPPS (EN-1822).
Prefiltration: Inlet G3 pre-filter efficiency 80≤AM≤90 according to EN 779 and UNI 10339.
Operation Condition: Air cleanliness in Class ISO 3 as per ISO:EN 14644-1.
The user-friendly practical keyboard and the rear-lit LCD will continuously display all required data keeping the user constantly informed of the cabinet conditions in operation, and in particular:
- display of laminar airflow velocity and frontal air barrier velocity
- display of inside and outside temperature
- display of residual lifetime of HEPA/ULPA filters, UV Lamp and activated carbon filter (if fitted)
- display of total number of hours of operation
- display of saturation level of HEPA/ULPA filters
Audio-visual alarms provided for:
- out of range or incorrect laminar airflow velocity and frontal air barrier velocity
- incorrect position of front sash-window
- clogging of HEPA/ULPA filters
- end of life-cycle of UV lamp and saturation of activated carbon filter (if fitted)
- blockage in the exhaust duct ( if fitted )
- fan-motor malfunction
- power failure
Lighting: fluorescent tubes in built-in housing, placed outside the contaminated area
D.O.P.-DEHS inlet port for testing the HEPA/ULPA filters
Exhaust hard duct connection: due to their intrinsic feature to exhaust all air treated, SafeFAST Elite Total Exhaust are supplied with a 300mm diameter collar on top of the unit for direct connection to exhaust system.
Magnetic and removable UV sterilizing lamp (optional) that can be easily placed in each area of the back wall. It is completed with two switch-off countdown timers, one variable on a 0-3 hours scale (1 minute steps), the other set to 3 fixed hours.
