▶ 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.
