SafeFAST Top class II A1/A2 Microbiological Safety Cabinets belong to the latest generation of laminar airflow systems manufactured by Faster, in which the choice of materials of construction of the highest quality guarantees conformity to the strictest safety standards.
Faster SafeFAST Top are Microbiological Safety Cabinets - designed and built to performance requirements of the EN-12469:2000 European Standard and NSF/ANSI 49 American Standard, with 70% of the air re-circulated via the main Class H14 HEPA/ULPA filter within the cabinet, whilst the remaining 30% is discharged through an exhaust Class H14 HEPA/ULPA filter.
BENEFITS
Best technical solution - cleanability first of all: Front stratified hinged safety glass, the frontal opening is set to 200 mm. The whole front of the safety cabinet can also be opened upwards as it is hinged on the top – in order to allow easy access for complete and effective cleaning and decontamination. Single piece work chamber in stainless steel AISI 304 designed to fuilfill the requirements and pass the cleanibility test according to EN 12469:2000.
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.
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 H 14 HEPA/ULPA filters.
Easy handling and maintenance: The cabinet can pass through standard 800 mm wide door openings. In fact, the overall depth of the cabinet is 785mm. All service operations are available from the front of the cabinet.
Automatic safety service connections for gas and vacuum and one electrical socket fitted as standard in each size model.
OPERATIONAL PRINCIPLES
The ambient air is drawn in from the slots at the stainless-steel base of the front opening and it then passes under the work surface, from where it is drawn up and blown into the plenum of the re-circulating and exhaust fan(s).
The “bio-dynamic sealing system” of the negative pressure plenum ensures that all contaminated particles are kept inside the system and are automatically drawn to the plenum or pressure chamber to be captured by the main re-circulating and exhaust H 14 HEPA/ULPA filters. The fan system assures that no part of the cabinet comes ever under positive contaminated pressure to the laboratory, thus protecting and preserving the environment and operating personnel from exposure to agents of bio-contamination.
70% of the filtered air is re-circulated (after passing through a H14 HEPA/ULPA filter) in an air cleanless in Class ISO 3, according to ISO 14644-1 laminar flow pattern downwards into the work chamber and the remaining 30% is exhausted to atmosphere through another H14 HEPA/ULPA filter.
