Equalization box FläktGroup ATTD-100-160-1 damped [8613395]

The ATTD product family includes a balancing box suitable for all diffuser models. The diffuser connection collar in the balancing box faces either outwards or inwards, which reduces the space requirement for the box. The ATTD balancing box is suitable for both supply and extract air. In extract air use, the position of the measuring hose in the control section is changed to the measuring connection inside the box. The sound attenuation elements are designed to control the airflow to achieve the most even air distribution possible. They are easy to remove for cleaning. The patented multi-point measurement of the measuring and adjusting device enables even and accurate measurement results. The adjustment handle of the measuring and adjusting device has an adjustment position indicator and a lock. For small adjustment flap openings (0-1), the measuring and adjusting device has a fine adjustment function, which is operated by turning the adjustment spindle of the adjustment handle. For larger openings (1-5), adjustment is done quickly with a sliding adjustment.
The adjustment position is locked by turning the adjustment spindle clockwise to the locking position. The adjustment and measuring device can be easily removed for inspection and cleaning without changing the adjustment position and without having to remove the sound attenuating element. The k-values ​​for different installation methods (supply air) are marked on the adjustment cable. The k-values ​​for extract air can be found in the diffuser-specific adjustment instructions.
