Product description
The ComfoAir 70 is a decentralized or semi-centralized ventilation unit with waste heat recovery for a healthy, well-balanced,
energy-saving, and user-friendly ventilation system. The unit can be used in a single room as an isolated solution or ducted for
multiple rooms. With this ComfoAir 70 application as a semi-centralized ventilation system, air can be extracted from the kitchen
and/or bathroom using adjoining room connections, and the fresh air introduced into the living room and/or bedrooms.
An enthalpy exchanger, which can transfer both humidity and heat, is used in the ComfoAir 70 for energy recovery. The housing
consists of a powder-coated steel plate, as well as covers made of aluminum in the RAL9016 color scheme. The unit body, made
from a high-quality expanded polypropylene (EPP), is used for accommodating the unit components, and also makes sure there is
the necessary insulation and unit soundproofing.
The ComfoAir 70 has two maintenance-free, 24 VDC radial fans with electronic commutation. These fans and the control board
receive the required operating voltage via an integrated 110 or 220 VAC / 24 VDC transformer.
By default, a class G4 (MERV 8) air filter is used in the unit for the outdoor air and the exhaust air. As an option, a class F7 (MERV
13) air filter for pollen can be used for the outdoor air.
The exterior wall hood is made from white aluminum.
The ComfoAir 70 has valves that, when in specific operating modes, automatically close off the outdoor air supply and indoor air
exhaust sections in the unit.
