Profile: Schaefer Ventilation Equipment manufactures agricultural, commercial/Industrial and horticultural ventilation equipment. We offer ventilation blowers, which contains sleeve bearings suitable for all position mounting. Tunnel ventilation with evaporative cooling gives a complete control of the environment for cow cooling. The control system integrates temperature and humidity sensors to turn fans and pads on and off during the day and night. We provide Mighty Mister®, which is a portable misting system that cools down with a chilled mist that reduces the body temperature providing heat relief.
