Cabin ventilation
Apart from optimal venting, it is also important that an
adequate supply of fresh air is introduced into the cabin.
The air intake vents in the effective cross section should
therefore be larger than the air-intake vents in the
tanning system to avoid undesirable drafts.
For the unit VIVA Prestige, a cross section of 4500 cm²
should be provided. It is also advisable to position the
air intake vents on the lower sections of the cabin walls.
Exhaust hose placement and hose
diameter
For units of the line VIVA Prestige, a hose with a diameter
of 400 mm (nominal size) (inside diameter 375 mm)
should be used.
In addition to the diameter, the placement of the hose is
also very important. Ideally the hose should lead away
from the unit in a straight line. Every bend in the hose
increases the air resistance within it. 180-degree bends
should be avoided as a rule.
If one or more bends are necessary nevertheless,
please note that this reduces the overall length of the
hose unless a booster fan is used.
A hose length of about 4 meters may be used without
the addition of a booster fan if it is placed in a straight
line.
Therefore, when using a long hose with many bends, it
is advisable to use a booster fan in every case. The exit
cross-section of the hose should under no
circumstances be reduced, as an air jam will otherwise
occur.
