Vaillant VAZ-G160 silencer insert for recoVAIR VAR 60

Product detailed description

VAZ-G160 is an original damping (acoustic) insert with a diameter of 160 mm, designed as supplementary sound insulation for the installation duct of Vaillant recoVAIR VAR 60/2 D and DW local heat recovery ventilation units. The insert is fitted into the VAZ installation pipe together with the VAZ WD160 outdoor cover and further reduces the transmission of noise from the exterior to the interior through the opening for the ventilation unit, beyond the standard attenuation provided by the pipe and cover alone.

Technical description and purpose

The 162 mm diameter opening required for installing the recoVAIR VAR 60/2 unit represents a point in the perimeter wall with significantly lower sound insulation than the surrounding wall without an opening – even despite the standard damping element in the VAZ WD160 cover, it may therefore be desirable in some locations (proximity to a busy road, airport, railway, noisy city centre street) to achieve an even higher level of acoustic attenuation. This is exactly the purpose of the VAZ-G160 damping insert, which is fitted inside the installation pipe and, through its acoustic structure, absorbs part of the sound energy passing through the duct, thereby contributing to overall attenuation exceeding the standard value of 42 – 50 dB achieved by the combination of pipe and cover without this insert.

The insert is designed so as not to obstruct the required airflow needed for correct operation of the recoVAIR unit at its maximum output (up to 60 m³/h), while maximising acoustic attenuation within the given 160 mm duct diameter.

When to purchase the damping insert

We recommend considering the VAZ-G160 damping insert primarily for installations in exterior-noisy locations – flats and houses near busy roads, intersections, close to a railway line, an airport, or in a densely built-up city centre, where the standard level of noise attenuation provided by the installation pipe and WD160 cover is perceived as insufficient, especially in bedrooms and rooms intended for rest. The insert can also be added subsequently to an already existing installation without the need to replace the installation pipe or outdoor cover itself.

Broader context: acoustics of living rooms

The perception of noise in a living space depends not only on the absolute sound pressure level (measured in dB), but also on the frequency composition of the sound and on the type of room in question – in a bedroom or children's room, where night-time quiet is required, we perceive even relatively low levels of exterior noise more sensitively than, for example, in a kitchen or living room during the day. This is precisely why the VAZ-G160 damping insert is recommended primarily for rooms intended for sleeping and resting in exterior-noisy locations, while in less sensitive spaces (hallways, utility rooms, kitchens) the standard attenuation provided by the installation pipe and WD160 cover alone is often sufficient.

When to consider another solution instead of the damping insert

If the exterior noise at a specific location is extremely high (for example, immediate proximity to a busy intersection or railway line), the damping insert alone may not be a sufficient solution, and we recommend considering a more comprehensive assessment of the façade's acoustics with a building acoustics specialist, or possibly placing the ventilation unit on a less exposed side of the building, if this is layout-wise possible. In most typical residential locations in Slovakia, however, the combination of the installation pipe, VAZ WD160 cover, and this damping insert represents a sufficient and cost-effective solution.

Maintenance and filters

The recoVAIR VAR 60/2 unit uses a pair of filters – one ISO Coarse 45% class on the supply (outdoor) air side and one ISO Coarse 30% class on the extract (indoor) air side. Depending on operating conditions (urban environment, pollen season, proximity to a busy road), the filters need to be checked and replaced approximately 2 to 4 times a year; the display on the control panel or remote control will alert you when replacement is needed. Filter replacement is a self-service operation requiring no service intervention – the filter cartridge is simply pulled out and replaced with a new one.

The ceramic heat storage exchanger is a maintenance-free component with no moving parts, which under normal operation requires no cleaning or replacement throughout the unit's service life. We recommend having the fan checked once every few years during a regular service inspection of the heating/ventilation system, although it is a component designed for long-term maintenance-free operation.

Why choose this particular model

The VAZ-G160 damping insert is a simple and cost-effective way to increase acoustic comfort when installing a local heat recovery unit in a noisier exterior environment, without the need to fundamentally change the installation concept or purchase a different type of installation pipe or cover.

Frequently Asked Questions

Compatibility check by order code

Vaillant products are identified in internal documentation and price lists by a ten-digit order code (e.g. 0010047352 for this damping insert), which uniquely identifies the specific product variant. When ordering accessories for the recoVAIR system, we recommend always comparing the order code with the documentation of your existing installation to guarantee a 100% match between the insert's diameter and the installation pipe.

Service, distribution, and availability of spare parts in Slovakia

Vaillant has an established network of authorized service partners and wholesale distribution of spare parts in Slovakia, thanks to which the availability of accessories for the recoVAIR range (installation pipes, outdoor covers, control panels, filters, and small parts such as damping inserts) is ensured in the long term even after sales of a specific generation of units have ended. When ordering any accessories, we always recommend stating the exact production code shown on the unit or in its documentation to guarantee 100% compatibility with your specific installation (especially when distinguishing between the VAR 60/1 and VAR 60/2 generations, which differ in some components).

When purchasing from atria.sk, you can count on expert advice in selecting the right accessories for your specific recoVAIR unit model, as well as the option to order other related Vaillant products (boilers, heat pumps, water heaters) within a single order.

Practical tip for ordering and installation

If you are unsure whether your location requires a supplementary acoustic insert, we recommend first assessing the subjective noise level with the window open in the room in question, both during the day and at night – if noise from the street or traffic is noticeably disturbing even with the window closed, it is likely that a supplementary insert in the installation duct will bring a noticeable improvement in acoustic comfort. The insert can be ordered and fitted additionally at any time even after the original installation is completed, without needing to interrupt the unit's operation for an extended period.
