FRESH TL-F
Ventilationsprodukter för bostäder, affärer & lokaler
Fresh TL98F is a new unique
wallvent with a condensationprotected
design which gives a very comfortable
distribution pattern.
The vent is also perfectly suited for
floorheating. A dust & insect filter is
included as standard.
The airflow is adjusted by a variable
precision damper which is adjusted
by a regulator underneath the front
cover. The vent is available in
soundreducing model.
• Variable airflow adjustment
• Condensation protected
• Distribution pattern for
floor heating
• Built-in minimum-flow
• Several filter alternatives
Mounting
A high placing on the wall is
recommended. With advantage the vent
can be used in rooms with floor heating
as it has been designed mainly for this
solution. If there is a radiator in the
room the vent should be placed above it.
With this solution, the convection flow is
used and maximum comfort is achieved.

Flimmer ® filter
Fresh Flimmer ® filter particle separation
The Flimmer ® filter is the first threedimensional
filter in the world where particle separation
takes place along the fibres, in contrast to
conventional bag and barrier filters, where
the air is directed across the fibres.
• High particle separation (F7).
