description
The ComfoAir 70 is built to the current state of the art and the recognized safety regulations. The unit is subject to
continuous improvement and development. This is why it is possible for your unit to deviate slightly from the description.
Unit design and function
The ComfoAir 70 is a decentralised comfort ventilation unit, with heat and humidity recovery, using synchronous supply
and extract air operation. The ventilation unit can be used both for individual room ventilation (room-by-room) and, via
connection options for ventilation tubes, for venting of a group of rooms (utilisation unit). The ventilation unit is designed
for permanent operation and is only to be taken out of operation for maintenance and repair work. With the appropriate
(optional) sensor technology in the unit, fully automatic, demand-controlled ventilation operation is possible.
The housing consists of a powder-coated steel plate, as well as covers made of aluminium in the RAL9016 colour scheme.
The body of the unit, which is made of high-quality polypropylene (EPP), is used to house the main assemblies, provide
thermal insulation and sound protection for the unit.
The enthalpy exchanger used as standard in the unit ensures a healthy, comfortable indoor climate with its high heat and
moisture recovery.
Both of the maintenance-free centrifugal fans are driven by energy-efficient EC direct-current motors. The fan output in the
form of the air volume flow can be adjusted in four stages. In the automatic operating mode, the air volume flow is
continuously controlled.
A fully automatic shutter control activates the motorised shutters as required for standby and frost protection mode.
The ventilation unit requires very little maintenance, but it is important to change the air filter regularly. Inside the unit, there
is a filter with filter class ISO coarse 70% for the outdoor air and another one for the extract air in serial production.
Optionally, a filter of filter class ISO ePM10 80% can be used for filtering the outdoor air.
As a facade finish, an exterior wall panel is available in three different types of material: white aluminium, white ABS plastic,
or stainless steel.
