Careful of the direction of air flow! The non-return damper must be removable, accessible for service and maintenance. The axis of the check damper must always be horizontal. Rotation of the axis will prevent proper operation. Place the check damper perpendicular to the pipe, max. 0°- 5° against the direction of air flow. For servicing, we recommend mounting the damper in the RD service part - instabox.
