INvisible force + combined Function

High-quality VFD ventilation flap drive with integrated locking function for demanding architectural projects

The VFD ventilation flap drive impresses with its innovative design: hidden from view in the sash and barely noticeable even when open. The globally unique and patented combination of opening and locking mechanism drive in a compact motor gear unit combines maximum ease of use with efficiency.

A brushless motor, high-quality materials, and a whisper-quiet planetary gearbox make it durable and robust. Solutions for individual project requirements are made possible by the uncomplicated plug-and-play installation, flexible sash opening widths of up to 130°, and the automatic teach-in function. If required, VFD solutions can also receive approval for smoke and heat extraction applications.
