This rack is a transmission component of the rack-and-pinion drive system that enables ventilation curtains or windows in agricultural facilities, such as poultry houses and greenhouses, to be opened and closed by motor. Its 2.5 mm thick galvanised steel construction offers high corrosion resistance against the damp, ammonia vapour and dusty conditions commonly encountered in poultry house environments. The U-channel body design both enhances mechanical strength and facilitates mounting onto the curtain shaft. The tooth geometry is designed to ensure smooth, low-wear engagement with the drive pinion. It offers a durable, low-maintenance solution for modern poultry houses and greenhouse operations that utilise automatic climate control.
