▶ Vertical
Laminar Flow. Sterile area.
To ensure the reliabolity of any tests, it
is of vital importance that
work performed inside the hood is not contaminated.
CRUMA Vertical Laminar Flow Cabinets for Class
100 cleanrooms
create this sterile environment by basing
their construction on the
following special festures:
· Polymer coating to protect metal parts against
corrosion.
· Side and front walls formed by 8mm thick
transparent
acrylic panels.
· Working surface of white safety glass.
· Silent radial centrifugal fan.
· Operation guaranteed for more than 50,000
hours.
· In compliance with current legislation,
fitted with gas,
electricity and
vacuum connections.
The filtration system incorporates a replaceable
filter that is
fireproof, water-repellent and has been given
a bactericide and
fungicide treatment in compliance with the
current requirements
of the European Standards EN-1822 and DIN
24184.
The filter is an absolute HEPA(High
Efficiency Particulate Air)
class H14, with a minimum efficiency of 99.995%.
To ratain atmospheric dust particles, models
870 FL and
670 FL sterile cabinets are fitted with
a class G4 synthetic biofibre prefilter(as
per EN-779 standard) |

Decontamination Gruarantee. |

CRUMA 870 FL and 670 FL sterile
cabinets are delivered with a 15W UV germicide
lamp designed to decontaminate
the hood before and after use. The lamps are
an artificial source
of ultraviolet radiation ensuring accurate
germicide power: 225 microwatts per ㎠ at 0.50
m.
Care should always be taken never to expose
eyes or any other unproteced part of body
to UV rays.
For this reason, even though the transparent
methacrylate walls and front door of CRUMA
sterille cabinets
block these rays, no work should ever be carried
out when the germiclde lamp is turned on.
Just like all other CRUMA fume hoods, Vertical
Laminar Flow cabinets can be mounted on the
portable
MOVILAIR support
and are fully guaranteed
for 3 years against any manufacturing
defects,
except for the filters which are a consumable
item. |
