ArtA is an active silencer for HVAC (Heating Ventilation & Air Conditioning) networks. It can be fitted in networks of circular or rectangular section.
ArtA is a very efficient alternative to traditional noise traps with baffles, and provides an optimal acoustic recognition, relying on the two following technologies:

- An Active Noise Reduction technology particularly efficient in the low frequency range. These frequencies are very inconvenient and usually very difficult to treat in HVAC networks.

- A Passive technology relying on an acoustic bulb and a rock wool envelope to trap the medium and high frequencies.

Characteristics
Standard diameters of the ducts treated are in the 250 to 630 mm range, but there are no technical limitations for larger or smaller sizes.
Square or circular section.
Wide operating range: Airflows from 1 500 to 10 000 cubic meters per hour. For higher airflows, ArtA’s can be installed in parallel.
Electric supply : 230 V~.
No specific maintenance operations required (only periodical cleaning depending on environment).

The ArtA technology can be implemented in silencers designed for specific industrial applications, for example to reduce noise created  a factory.
