getAir's SmartFan® L Plus fits into any window reveal without a problem. The decentralised home ventilation unit can be installed in an exterior insulation and finish system (EIFS) just 60mm thick. A further advantage of installing the SmartFan® L Plus is its near invisibility. On account of its smart installation technique, only two components are needed to install the ventilation unit: an insulation element made of patented Neopor® is inserted directly into the window reveal, while an installation cylinder containing the fan unit and ceramic heat exchanger is concealed in a core-drilled hole (just 162 millimetres in diameter) in the outside wall. The only component visible from the outside is the unobtrusive grille.
Exceptionally low operating noise
The home ventilation unit with the lowest noise level in its class, the SmartFan® L Plus features optimal sound insulation and airflow. Apart from its good sound protection, any operating noise caused by the fan unit is hardly audible due to the use of sound-absorbing mats. Moreover, the electromagnetic motor with vibration control reduces any fan noise to a minimum. In addition, the sleek inside cover is fitted with a noise deflector. And its patented multi-membrane plastic coating further reduces any airflow noise.
Twofold sound deflection
Achieves sound insulation class 6
The SmartFan® L Plus features a very high level of sound insulation and is very good at absorbing outside noise. The twofold airflow deflection within the ventilation unit minimises transmission noise. Moreover, the unit has an additional sound absorption mat, thereby allowing it to achieve excellent acoustic values in the area of sound insulation class 6. This means that the SmartFan® L Plus offers more than 60 dB protection, and is thus suitable for use in buildings near airports, railways, main roads and other very noisy places.
Interactive elements Change
Thanks to the 180° coupling system
You can twist and turn the SmartFan® L Plus to achieve the right installation form. The system consists of two Styrofoam elements, coupled together at any 180° angle, and allowing the ventilation unit to be installed on either side of the window. This is very practical, with just one system covering two installation options.
A smart mix of proven and innovative technology
As with all getAir systems, the SmartFan® L Plus window reveal solution is based on the SmartFan® technology. Each getAir ventilation unit is a compact power pack which, operated in pairs, can move between 18 and 46 m³/h of air with simultaneous heat recovery of up to 91 percent, reducing heating bills by up to 50%. But the ventilation system is not just for use in winter: running in summer mode, it pumps in cool air at night, meaning that rooms do not get too hot. As with all SmartFan® products, the SmartFan® L Plus can be operated via a multifunctional TOUCH control screen or an intuitive LED operating panel, thus fulfilling all requirements for a mature, smart and up-to-date decentralised home ventilation unit.

SmartFan® L Plus – extremely quiet and practically invisible
The SmartFan® L Plus provides optimal ventilation, while at the same time shutting out noise. Especially in residential areas with high noise pollution, for instance near airports, railways or main roads, installation of a decentralised ventilation unit significantly upgrades a building. Fresh air without noise: finally possible with the SmartFan® L Plus.
The mounting tube must protrude ca. 5 mm on the outside of
the wall to ensure a correct connection to the window reveal
duct. In the case of any indoor plastering work not yet being
completed, take account of the thickness of the future plaster
when shortening the mounting tube (1). Please comply with
the required wall thickness of the planned ventilation unit
when shortening the mounting tube.
Follow the installation instructions for the ventilation unit
and cut a slit in the indoor side of the mounting tube (2) to
accommodate the cable to the fan unit. When using thicker
cables, the slit will need to be wider.
Coat the outside of the mounting tube with the sealant (1) and
insert it into the hole (2). The mounting tube must protrude ca.
5 mm on the outside. Pay attention to how long the sealant
needs to dry. Proceed to the next step.
Make sure that the mounting tube is sealed correctly against
the wall (1). Align the reveal duct horizontally and fasten it to
the brickwork or EIFS using a suitable adhesive (2). In doing so,
take any future layer of plaster into account. While the adhesive
is drying, you will need to support the duct.
While completing work on the outside facade, insert the
plastering cover (1) into the reveal duct to prevent dirt getting
into it. In line with the future layer of plaster, let the plastering
cover protrude + 10 mm. Complete work on the facade (2).
Remove the plastering cover from the reveal duct. Remove any
plaster obstructing the opening. Align the reveal grille with the
duct‘s opening. Align the grille by placing the outwardly facing
edge of the grille about 15 mm away from the outer edge of
the opening (1). Make sure that the grille is correctly positioned
and that the edge with the swelling tape sits ca. 2 - 3 mm under
the duct’s entrance to ensure that any condensate drains off
properly. Mark the drill positions (2). Use the supplied fi xing set
to securely install the grille over the opening in the reveal.
