Our ducts come with an automated internal tube membrane that adjusts to temperature and seasons with the flick of a lever. A positive pressure system brings fresh air in and a negative system flushes the air out. This technology is especially useful during spring and fall when the days are warm, and the nights are cool.

Protect your calves

Flap ducts are particularly good at matching the quality of air in hutches in every season. Protect your biggest investment—your calves.
