SAU供气装置为良好的室内环境要求而设计，提供加热过的洁净空气，整套系统由过滤器，风机和加热器组成。

SAU125和200可以使用双控制器来操作，加热器的开/关和风机速度的0/1/2.它也可以通过脉冲发生器来调节。SAU250的水电池是通过一个三通阀控制设备来操作。

风机外壳是有镀锌钢板制成，SAU机组使用的是50mm的矿物棉来消音的，这使得它适用于温暖或者寒冷地区。过滤器G4，F4，和F7都是可供选择使用的。

SUPPLY

Change the "User input" by dragging the point, or by entering new values.

EXTRACT

Change the "User input" by dragging the point, or by entering new values.

COMBINED

Temperature efficiency is calculated at balanced airflow. Flow from the EXTRACT side is used.

SFP is calculated for 2 fans.
