3.3. Air extraction
3.3.1. Fresh air inlet
To obtain an optimum performance and make drying cycles as short as possible, make
sure that fresh air enters from outside the room.
It is advisable that the fresh air inlet be behind the dryer.
The fresh air inlet section must be at least 4 times bigger than the air outlet tube section.
Note: The fresh air inlet section is equal to the section through which the air can flow without
resistance due to the bars or grille installed in the inlet. Take into account that the bars or grille
can often represent a big part of the inlet section.
3.3.2. Outlet pipe
Moist air must be channelled to the outside using the connection of a pipe with a net
diameter corresponding to the outer diameter of the steam outlet tube, located on the bottom
back part of the machine. The extraction air must be taken to the outside of the work place and
must never be connected to other chimneys already in use that extract smoke from other fuels.
The location of these conduits must be under the limits established in environmental thermal
legislation. A tube made in temperature resistant material must be used (150 ºC). Never leave the
tube very near inflammable materials or materials susceptible to deformation from excessive
temperatures.
The tube must be smooth inside. It is important that there are no elements in the way of the air
path or that might accumulate fluff (bolts, rivets...). Systems for the periodic inspection and
cleaning of the conduits must be foreseen.
