Designed as an S-FAN ™ compact hot swap active silencer, the Axial Fan is installed at the end of the exhaust or intake port to provide noise reduction in the audible frequency range of approximately 10dB (A). The compact S-FAN ™ can be customized for fan sizes or other blowers, such as air devices. The goal of this product is to reduce the noise emitted by the airflow of all electronic products. For more information, please contact FiveGT or Silentium representative.
|Dimensions||L=420mm, W=100mm, H=160mm|
|Weight||5kg (Power adaptors ~0.5kg)|

The SCDK™ provides a do-it-yourself ANR development tool that can be used for the application of loud electronic equipment. Developers and engineers can leverage it to implement noise and vibration reduction. The controller unit integrates all the required function: Sound generator, equalization, amplification and the active adjustment processor. The controller is connected directly to the loudspeakers. The controller allows the designer to reduce up to 10dB reduction in addition to what the acoustic materials will diminish.

|10m x 1.5m (H)||67.9 dB (A)||61.7 dB (A)||▼ 6.2 dB (A)|
Optimized IT solution with perfect noise shielding and efficient cooling efficiency
We guarantee a quiet and pleasant environment when building servers in offices, laboratories, assembly lines, etc.
When ASFT is operated inside the rack, 8kW of hot air is discharged when the temperature difference of Inlet is kept below 20 degrees, which provides excellent cooling efficiency without any separate air flow control.
