Manufactured of high density polyethylene, our dual wall shell design allows the exterior wall to absorb external damage without disturbing internal mechanisms or airflow. With Schaefer's VAF-Series ventilators, maintenance costs are virtually eliminated. Rated at 100,000+ continuous duty hours, our custom built motors are designed to perform in the harshest of environments. Schaefer's Americ ventilators have totally enclosed motors that eliminate the possibility of debris buildup on the copper windings.
