ROOF FAN ONNLINE 20-2-1

The Onnline ceiling-mounted exhaust fans are designed for mechanical ventilation exhaust in single-family homes. The fans feature a permanently lubricated motor that requires no separate maintenance. The fan unit can be removed for cleaning and duct clearing. The separate roof penetration is insulated and functions as an effective sound dampener. The electrical cable penetration tube is also pre-installed. The roof penetration is equipped with a 160 mm duct connection. The exhaust fans are connected to the electrical network via a controller, which can be mounted in a control box or, for example, an Onnline thyristor controller can be used as the controller.
