These Panasonic ceiling mount ventilating fan models use a low noise sirocco fan driven by a capacitor motor.
The motor is designed to have an extended service life with reduced energy consumption.
It also incorporates a thermal-cutoff for safety. The grille covering the main body is a spring-loaded, quick-remove type.
A damper for preventing counterflow is provided.
