Product description
Information

The flapper has a tight design according to ÖN M 6027. The flapper sheet is made up of a frame and a silicone membrane. It is suitable for installation in vertical (depending on type) or horizontal position. Installation is done by inserting it into the pipe. The flapper has a double-barrelled seal for sealing and fixing in the pipe.

- insertable into circular piping
- self-sealing design with magnet
- made of plastic
- double-barrelled seal
- preferably installed vertically
- operating temperature up to 80 °C

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.
