The quietest WOLF mechanical ventilation ever

Nine convincing arguments for you and your customers


WOLF Residential ventilation point 1 CWL 2

Compact and efficient

State-of-the-art technologies ensure outstanding thermal and electrical efficiency. At the same time, the CWL-2 offers incomparably low sound levels. The complete redesign makes this appliance the most compact in its class, even with the preheater integrated as standard.


WOLF Residential ventilation point 2 CWL 2

Quieter than ever before

Thanks to the aerodynamic internal configuration and the newly designed components, the appliance runs extremely quietly, even at high speeds. It is therefore usually possible to avoid the use of external silencers. WOLF ventilation units are ideally suited to the new flow- and maintenance-optimised UniAir design valves in the round and rectangular versions.


WOLF Residential ventilation point 3 CWL 2

Perfect balance

The latest fan technology ensures an optimally-adjusted flow rate. The precise flow rate measurement with impeller anemometer guarantees smooth running and balanced flow rates. At the same time, this technology creates a clearer structure and a high level of serviceability.


WOLF Residential ventilation point 4 CWL 2

Perfect design 

In combination with the new WOLF UniAir supply and extract air design valves, the CWL-2 series looks refined yet discreet and will fit into any interior. In the modern silver-stripe design, the CWL-2 appliance series perfectly fits in with the current WOLF look.


WOLF Residential ventilation point 5 CWL 2

Enthalpy heat exchanger

The CWL-2 is also available with an optional moisture-recovering heat exchanger (accessory). Thanks to the antibacterial polymer electrolyte membrane (PEM), no odours or pollutants are released into the supply air - for optimum hygiene and comfort. A separate drain connection is no longer required.


WOLF Residential ventilation point 6 CWL 2

Comfort as standard

The CWL-2 thinks for you: the intelligently-controlled preheater ensures trouble-free ventilation at low outside temperatures. The fully automatic bypass function means that cool outside air can be used at night in summer. All of these features are standard with WOLF.


WOLF Residential ventilation point 7 CWL 2

Simple configuration & maintenance

With the new colour touch display, you can now operate the appliance even more easily. The digital step-by-step instructions guide you through installation and filter changes quickly and intuitively. The ball siphon guarantees maintenance-free condensate management and fault-free installation.


WOLF Residential ventilation point 8 CWL 2

Directly online

With the optional WOLF Link home interface module (accessory) and the Smartset portal, you can monitor your customers' systems via the internet at any time. This makes it easy to read the status of the system and optimise settings without costly travel.


WOLF Residential ventilation point 9 CWL 2

The perfect package

CWL-2 mechanical ventilation units are the ideal complement to WOLF heat generators. The efficient and complete system with perfectly coordinated components can be easily controlled from a single programming unit or using the WOLF Smartset app (or the portal).
