The Hartzell Fiberglass Centrifugal Roof Exhausters provide a low profile roof exhaust solution in a corrosive environment.

Hartzell fiberglass roof ventilators are a practical choice for industrial applications where corrosive elements exist in fume and vapor form but still provide the advantages of positive and accurate ventilation, regardless of internal plant and weather conditions. As an added dividend, fiberglass roof vents provide weather-resistant characteristics, will not tarnish, and will never need painting. The housings are extremely durable and highly resistant to impact.
