The Top Safe Cabinets are supplied in three different sizes (1.2 mt, 1,5 mt). These last generation Microbiological Safety Cabinets have been certified according to the most stringent safety standards
(EN 12469 : 2000). The internal design, the air flow aerodynamics and monitoring, the built-in safety devices and the very accurate manufacturing, guarantees the highest performances at the most stringent safety levels, as specified by EN 12496 : 2000 standard and have been tested by the most prestigious European certification bodies for Safety Cabinets.
Fully EN12469 certified by Tüv

Sloped front design for the highest
operational comfort. Sloped back side of
the working chamber for the best down
flow distribution (cabinet carcass
EN12298 tested and certified for air
tightness)
Utilities inlets from the top of the
cabinet.
Stainless Steel internal surfaces with 2B
finishing (including spillage tray). Solid
work surface (3 sections) and special
designed front grill.
Exhaust grill (Class I) with high
aerodynamic efficiency for a reduced
turbulence exhaust air pattern inside the
cabinet
Comfortable 200mm front opening
Easy to install retrofit options through
lateral sides.
Exposed exhaust Hepa filter for easy
visual integrity check.
H14 class High Efficiency Particulate Air
filters with 99.999% efficiency on
.3micron particles (most penetrating
particle diameter) (EN1822-1 and EN
13091:1999 tested and certified)
Both exhaust and main filters (Class II
type A2) are equipped with a micromesh
membrane located downstream which
acts as airspeed equalizer expansion
plenum, as well as a clear indicator of
filter damages.
Filter change and maintenance from the
front of the cabinet.
Exhaust transitions easily installable.
Anti-blow-back valve available as add-on
option
Key operated. The key can be removed
when the unit is in SAFE mode, in order
to avoid unwanted operation. In case of
power failure, the cabinet is re-set to
original working conditions.
Self calibration cycle performed when
cabinet is switched on.
High speed rinse and set up cycle
performed, before reaching the SAFE
operating mode. |

Visual display of SAFE conditions. Pre-
warning before actual alarm conditions
are reached (visual and acoustic alarms)
Soft touch control with keys for standard
service utilities. Interconnected UV and
fluorescent lights.
For Class II type A2 models, the exhaust
and recirculating flow rates ensure 25 air
changes/min in the working area (30%
70% split)
For Class II type A2 models, the front
barrier air speed is ≥ 0.5mt/sec
For Class I model, the total exhausted
air flow ensures a minimum average
front speed ≥ 0.7m/sec
Aperture protection Factor (Apf) ≥ 1.5 x
10 exp 5
