Twin City Fan & Blower is proud to introduce our new line of Gravity Relief & Intake Ventilators, including both hooded and louvered penthouse designs.

Hooded Ventilators
Models TEH (exhaust/ relief) and TIH (fresh air intake) Hooded Ventilators are designed with aerodynamically shaped airflow passages for efficient operation and feature low silhouette style hoods to blend in with rooftop lines and equipment. A full 360° perimeter hood opening allows for more reliable airflow performance and low resistance.

Louvered Penthouse Ventilators
Models TEL (exhaust/ relief) and TIL (fresh air intake) Louvered Penthouse Ventilators are aerodynamically designed with generous airflow areas for efficient performance and offer pleasant low silhouette lines that blend with modernistic roof designs. Ventilators are louvered on all four sides for full 360° perimeter opening.

All hooded and louvered penthouse models feature aluminum construction as standard and have a full range of options available.
