Presentation
The ActA active silencer is also equipped with traditional passive attenuation devices such as rock wool and an acoustic bulb so it can also deal with high and medium frequencies.
This combination of traditional passive techniques and active noise cancelling technology results in optimal noise abatement for all audible frequencies (20Hz-20kHz).
principle
Application examples
Industrial: The installation of systems using TechnoFirst's EOLANE technology allows industrial sites to ensure their facilities comply with increasingly stringent European Standards and reduce the propagation of noise pollution in the vicinity of industrial sites (factory smokestacks, vacuum cleaners and/or fans).
performance
Main advantages:
- Very good radiated noise attenuation in ducts (airflow noise and fan noise), essentially in low frequencies.
- Very limited loss in pressure.
- Highly compact system saving at least 30% space compared with traditional solutions.
- Very easy to implement.
- Adapted to new facilities as well as the upgrade of existing facilities to comply with acoustic standards.
Technical specifications
- Inside duct diameter ranging from 250 to 630mm as standard
- Air flow treatment up to 10,000m3/hour
- Power supply: 230 V.
Standard ActA products are manufactured and installed by TechnoFirst-certified subcontractors, with the system electronics provided by TechnoFirst (please contact us). For all requests concerning non-standard products from the ActA range using the EOLANE process, TechnoFirst carries out adaptation Studies and Projects on request for products to be installed in its customers' systems.
