This complete fan system package can provide the same Multifan energy savings as the single unit fans, with the ease of installation and time savings of preassembly. A unique cast aluminum venturi is the Multifan secret to resisting traditional shrinkage and providing consistent uniformity in wing tip clearance. By avoiding size inconsistencies found in plastics, Multifan ventilation systems can generate maximum air capacity and ultimate energy efficiency. Aerodynamically designed hood directs airflow and protects against external wind pressure. Lightweight and easily installed, the Multifan unit provides increased environmental control with less energy!
