quented rooms, such as:
Waiting and reception areas
Meeting or conference rooms
Schools
Trade fair booths
Dining rooms
Shops

Functional description
Information about the unit
TROX AIR PURIFIERS TAP-L  TAP-M10

Fig. 4: Airflow
The TROX air purifier draws indoor air into the unit at
the lower air intake and feeds it to the filters. The pre-
filter separates coarser particles, then the HEPA filter
separates the smallest suspended particles from the
indoor air. A fan conveys the airflow through the unit
and returns the filtered air to the room via the upper
outlet. The sound attenuators placed in front and behind
the fan reduce the operating noise to a pleasant min-
imum.
With its operation, the TROX air purifier ensures a sig-
nificant reduction in particles and aerosol concentration
in rooms.
The effective filtering in conjunction with a high volume
flow rate (airflow rate) enables the air purifier to consid-
erably reduce the amount of germs, viruses and bac-
teria (depending on the room size) and thus also cut the
risk of infection.

cles contaminated with viruses and bacteria, we recom-
mend using only genuine TROX filters.
Original TROX filters carry a sticker on the frame with
both the use before date and information on how to
