Model Overview
The extremely quiet FF and FFC ventilators are available from 50 to 1,891 CFM, with static pressure capabilities to 1". All units have centrifugal blower wheels and low RPM motors on resilient mounts (except FF50 and AF80). These ventilators are used to exhaust air from a variety of commercial and institutional applications, such as restrooms, conference rooms, offices, storage areas, restaurants, retail stores, schools, and similar buildings to acquire a quiet atmosphere with your high-capacity ventilation needs.
The forward curved centrifugal wheel with its high static pressure capability makes these ventilators suitable for either ducted or non-ducted applications. They include removable blower assemblies and plug-in permanently lubricated motors for ease of service and cleaning.
