In 2016, Crystal Creek raised the bar again with FLAP DUCT, taking ventilation to an entirely new level. This technology builds on the innovation of FLIP DUCT, with an internal membrane that can be airtight… perforated… segmented… and layered. These internal membranes, or flaps, can be moved up or down to control air flow based on seasonal needs.
With this technology, the ability to regulate air speed is virtually limitless. Regardless of the calf housing setup, the requirements for delivering fresh air at the desired speed can always be met. Multiple aspects of the FLAP DUCT design are patented ( Patent #9,599,362. Additional foreign and domestic patents pending ).
