TROX Venetian Blind Flap JZ-A

Venetian blind flaps with lever linkages are coupled in parallel or in opposite directions. The synchronous rotary movement is transmitted from the drive lever to the individual slats by an external lever linkage. Even very large dimensions can be opened and closed safely with a lever linkage. Counter-rotating sipes close at different angular speeds because a wishbone is integrated into the lever linkage. As a result, the closing properties are better and the leakage air flow is lower when the blind flap is closed.

• Maximum dimensions 2000 × 1995 mm
• Housing leakage air flow according to EN 1751, class C
• Co-rotating or counter-rotating, flow-appropriate plates
• Coupling of the plates with external lever linkage (co-rotating or counter-rotating)
• In addition to the standard dimension series, numerous intermediate dimensions
• Also available in combination with weather protection grille
