Internal three-blade fan
The built-in fan assists airflow through the ventilator while remaining entirely wind powered.
Natural roof space ventilation with an internal three-blade fan to improve airflow. Superflow helps exhaust trapped heat and moisture from your home without using electricity.

Superflow combines a rotary roof ventilator with an internal three-blade fan to assist airflow through the roof space. It uses wind energy to draw out warm, stale air as fresh air enters through suitable inlet openings.
A fibreglass-reinforced nylon chassis, sealed dual bearing housing and double-riveted pressed vanes support quiet, durable operation.
Release hot air trapped between the ceiling and roof covering to help reduce heat radiating into rooms below.
Support air circulation and remove damp air when paired with suitable replacement-air openings.

The built-in fan assists airflow through the ventilator while remaining entirely wind powered.
Uses the energy of the wind, with no mains electrical connection required.
Exhausts hot or moisture-laden air from the roof cavity to support a better-ventilated home.
A sealed dual bearing housing and reinforced nylon chassis support quiet, reliable operation.
Double-riveted pressed vanes provide strength within the rotating ventilator head.
A variable-pitch base accommodates the roof types and pitch ranges listed in the specifications.

No. Both the rotary ventilator and its internal fan are wind driven. There is no mains electrical connection or electricity running cost.
Superflow includes an internal three-blade fan designed to improve airflow through the ventilator. It is powered by the wind-driven assembly rather than an electric motor.
The quantity depends on the roof dimensions, pitch, inlet openings and ventilation requirements. Use the technical bulletin and speak with Ampelite about the requirements of your roof.
Suitable replacement-air openings are essential for effective roof space ventilation. Eave vents help air circulate through the roof cavity. Check the technical bulletin for the inlet requirements that apply to your roof.
Yes, within the installation limits. The shared technical bulletin lists 3°–45° for metal sheet roofs and 15°–45° for tiled roofs. Follow the appropriate Superflow installation guide and ensure the rotating head is level.
