The LG 250 A compact ventilation unit is
used for controlled, mechanical ventilation
and deaeration of homes, large residential
units and offices and for similar purposes.
The scope of application normally extends
to living spaces between 80 m² and ap-
prox. 200 m², with an adjustable air flow
of up to 250 m³/h.
Operation is simple and intuitive and, with
use of a gateway can also be carried out
via the Pichlerluft app.
The gateway communicates via the Mod-
bus RTU connection of the building control
system (BCS). Therefore only either the
gateway or the Modbus RTU can be used
for the BCS, and not the two options at the
same time.
The LG 250 A compact ventilation unit
comprises:
• A compact, non-heat bridging and
thermally-insulated housing made from
galvanised steel sheeting, externally
powder-coated in RAL 9010.
• A high-efficiency heat recovery system
with air/air-counterflow heat exchanger
made from recyclable plastic with a
temperature change rate of 89,9 %
• An automatic 100 % bypass with ener-
gy-saving DC radial fans with constant
airflow control,
• Filter ODA ISO ePM2,5 65% in the out-
door air and filter ETA ISO Coarse 90% in
extract air.
• Internally wired electronic control
system.
• A "MINI" or "TOUCH" operating unit (op-
tional) , for standing or wall mounting in
spaces free from frost.
