Automatic Roof Ventilation

YORK® Roof Turbines are uniquely designed to provide efficient ventilation of commercial, industrial and agricultural buildings by automatically moving hot air outside, while preventing condensation inside. With rotor heads that respond to the slightest air movement, thanks to sensitive ball bearing action, YORK® turbines maintain suction even at low wind velocity. Centrifugal force, caused by the freely revolving head, creates a partial vacuum that immediately captures stale air and expels it.
