Pressure drying
When pressure drying, use L4 ES together with a turbine according to the schematic diagram below.
Pressure drying is two to four times faster than suction drying and is therefore the primary choice for a
layered structure, if there are no obstructions.

HE TURBINE IS FED WITH DRY AIR FROM THE DEHUMIDIFIER AND FORCES
IT INTO THE LAYERED STRUCTURE
.
During pressure drying, dry air is routed from L4 ES to a turbine and then forces this air into the layered
structure. In this way, warm and dry is forced down into the structure, which achieves the material
temperature and thus increases the rate of the drying process. Wet and cool air leaks into the room
through the gaps between the floor and the wall or via drilled check holes and is then re-sucked into the
dehumidifier as process air.
Before starting pressure drying, suction drying is required to evacuate all free-flowing water so that this
is not forced into other parts of the structure.
Pressure drying may release fibres/particles from the layered structure into the indoor air and if this is a
potential problem another method should be applied.
