12 13
Titanium apatite is a new photocatalytic
material with advanced adsorption power. While
the filter’s micron-level fibres trap dust, this photocatalyst
effectively adsorbs and decomposes bacteria and viruses,
and also breaks down mould and odours. The photocatalyst
is activated simply by exposure to light. The filter is
available with FTKD50/60/71F models.

Photocatalytic Mechanism
Light strikes the
photocatalyst and
activates the surface
particles.
A chemical reaction
decomposes the odours
into CO2, O3 and H2.
The odourless substances
are released into the air.

When cooling or dry operation is stopped, fan-only
operation runs automatically for 1 hour. This airflow
dries the inside of the indoor unit to reduce the
generation of mould and odours. It is available with
FTKD25/35D.
Mould-Proof Operation
Flat panel models can be cleaned instantly
with a single wipe of a cloth across their
smooth surface. If more thorough cleaning is
required, the panel can also be easily
removed from the unit.
Wipe-Clean Flat Panel
Front grille design units
collect dust on their air
inlet grilles unless these
grilles are cleaned
regularly.
1. Difficult to remove dust on the
grille through wiping alone
2. Reduced capacity due to
increased suction resistance
3. High sound levels due to
increased suction resistance

Air-Purifying Filter
This filter is able to remove impurities such as dust, pollen
and
cigarette smoke as well as bacteria and viruses from
the air. The filter is available with FTKD25/35D models.

Photocatalytic Deodorising Filter
The Photocatalytic Deodorising Filter is able to
decompose odours and even remove bacteria and
viruses. This filter can be used indefinitely if regular
maintenance is carried out. The filter is available with
FTKD25/35D models.

Apatite adsorbs bacteria and
viruses. At the same time, the
photocatalyst oxidises odour
components, breaking them down.
Viruses are decomposed into
clumps of protein and removed.
