Product description
Comfort 252/302 Top is a ventilation unit with heat recovery. The unit is intended for air volumes of up to 253/345 m
3
/h at an external
duct pressure of 100 Pa.
The unit is used primarily in residential buildings. Due to its low sound level it is particularly suitable for ventilation in apartments. The
unit ventilates the dwelling by drawing out damp and vitiated air through valves placed in, for instance, bathroom, lavatory, kitchen
and utility room. It then blows fresh outdoor air in through valves placed in living areas such as sitting room, family room and bedrooms.
The cold outdoor air is heated up by the warm extract air in the high efficiency counterflow heat exchanger. This ensures limited heat
loss through ventilation.
As standard, the unit is supplied with ISO Coarse > 90% (G4) plate filters that serve to protect the unit from dirt. If you require increased
filtration of the outdoor air, you can order an ePM1 50% (F7) pollen filter as an accessory.
