SafeFAST Elite - Class III

SafeFAST Elite class III are glove boxes designed with a frontal screen equipped with gloves, in order to isolate the applications from the operators. A transfer hatch (equipped with H 14 HEPA/ULPA filter) allows materials to be introduced into the Class III cabinet without breaking the integrity of the sealed enclosure. Gloves fitted upon glove-ports allow the users to manipulate the samples and products secure in the knowledge of complete isolation from the pathogens and infective or toxic materials being used.

Both the transfer hatch and working chamber volumes operate in negative pressure to the surrounding environment with the exhausted air being vented through a system of double H 14 HEPA/ULPA filters. Working chamber is bathed by Class ISO 3 laminar flow avoiding product cross-contamination.

Ergonomic Design: The angled sloping (7°) front stratified safety-glass provides optimum visibility of all objects placed in the interior workspace.

Real Laminar AirFlow: Frontal screen 7° sloped as well as back side wall to convey in unidirectional pattern the air flow. As a consequence, the front and back panels are parallel one with the other and there is the real presence of Laminar AirFlow in the whole working area.

Interlocking system: Internal and external door of the transfer hatch are synchronized by means of interlock system allowing the external door opening only when the internal door is closed in order to avoid contamination.

ECS® Eco Controling System: The new ECS® microprocessor employs the latest innovative methods of integrated management of all principal functions of ventilation and filtration - self-regulating all the main filtration and ventilation system components - compensating for declining pressure drops and restoring power balance. Combining the use of AC motor-blowers and certified low pressure-drop filters, the new ECS® controlling system optimize power consumption, reducing CO2 emissions into the environment.

Anti Bacterial Coating: Exclusive Dupont™ ALESTA® anti-bacterial “Ag+ cations-based solution”, capable to prevent microbial contamination of surfaces thereby inhibiting long term surface growth.

Silent Operation: The TNT plenum, the structures of the electric motors of the fans fitted on their antivibration mounts and the software itself designed to provide optimum air handling characteristics guarantee quiet operation of this silent safety cabinet, with sound-pressure levels recorded way below the parameters specified in the current EN:12469 European Standard for Microbiological Safety Cabinets.

High Level Lighting: The safety glass side-windows with the ideal positioning and sizing of the light-system provide the highest level of luminosity to the work area.

Footswitch: A footswitch is supplied as standard in order to un-lock the internal door of the chamber without removing the hands form the gloves.

Automatic safety service connections for gas and vacuum and one (for size 312) or two (for size 315 and 318) electrical socket(s) fitted as standard in each size model.

Glove Ports: 300mm glove ports with standard 0.4mm neoprene sleeves and gloves. Special gloves are available upon request. Unmatched abrasion resistance textile sleeves clamped with PVC flanges by means of strong rubber bands.
Flanges are rounded with 300mm diameter in order to have extra moving possibilities inside the working chamber to reach each point of the internal working chamber for effective daily cleaning procedures.

Transfer hatch made by epoxy coated steel and equipped with double in-line H14 HEPA/ULPA and classified as C2 type as per ISO-FDIS 14644-7.

Stainless Steel AISI 316L transfer hatch work surface with sliding tray to move samples and components inside the working chamber

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 consisting of sections (or in one piece upon request) which are easily removable for carrying out routine cleaning and/or autoclaving sterilization procedures; closed or perforated on request.

Individual testing ports positioned on the main chamber and the transfer hatch, in order to connect external devices for various testing such as air flow speed test and air cleanliness test without breaching the integrity of the system opening the frontal screen.

Re-circulating and extractor 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).

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

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.

Exhaust hard duct connection: due to their intrinsic feature to handle the most hazard group 4 of pathogens, SafeFAST Elite class III are supplied with a 200mm diameter collar on top of the unit for direct connection to exhaust system.

SafeFAST Elite Class III are tested for pressure tight and they overpass a pressure decay of 16 Pascal/minute
