Hartzell Direct Upblast Roof Ventilators are heavy‑duty exhaust fans engineered for rugged industrial rooftop ventilation. Designed to handle demanding air movement tasks such as general exhaust, heat removal, smoke control, and process ventilation, these units deliver reliable performance in tough environments. Built with durable construction and available in a range of sizes and materials, the upblast design directs airflow vertically upward, keeping discharged air clear of the roof surface and reducing recirculation back into the building. Hartzell roof ventilators feature precision‑engineered fan wheels and housings for efficient airflow and long service life, with options for weather‑resistant finishes to protect against corrosion and environmental exposure. With robust bearings, vibration‑dampening mounts, and industrial‑grade motors, these ventilators provide quiet, dependable operation and are suited for facilities where dependable exhaust performance and long‑term reliability are essential.
