Spiro is the eolic chimney top which is different for the quality and variety of raw materials used, finishing of the processing and, above all, for its functional characteristics.

The rotation system designed for continuous rotation even at very low wind speeds, is equipped with anti-lock mechanics, consisting of two oil-bath bearings in a watertight chamber turned from solid.

For this, the system is silent, efficient and really durable in time.

Spiro is projected and realized in the respect by the regulations, and its installation on a flue:

• improves suction capacity, helping to solve draft problems;
• avoids annoying fume returns;
• prevents the entry of foreign bodies, avoiding dangerous obstructions.

Spiro, thanks to the effective action of developed aspiration, can be used for ventilation of industrial buildings, warehouses, greenhouses, farms and wet houses often closed.

Spiro for its operating exploits the natural force of the upward air currents and of the wind, it does not need any maintenance in time.
