Fibreglass roof.

Base for securing to the roof.

Use: the exhaust asial towers are suitable for the suctin of vitiated air flue gases and vapour from the environment.They are very useful during the summer season in those environments where air changes are necessary in order to keep the room ventilated.
They are also used for the aeration of workshops, founderies, cement factories, tanneries, joineries, and for chemical mechanical and metallurgical industries where big air volumes have to be sucked at low pressure.

Minimum working temperature - 20 °C, maximum + 80 °C (+ 150°C with cooling fan).

The group is formed by a hight capacity centrifugal fan wheel ,which is statically and dynamically balanced .The centrifugal fan wheel is osperated by an electric motor of form B5-V1 and supported by a strong accident prevention galvanized net . It is installed on the building roof by placing it on its square basament and it is protected from the atmospheric agents by means of a fiber glass hood.

Characteristics:   V = 1.300÷15.000 m3/h      |       Pt = 13÷107 kg/m2

ErP: these fans are not subject to ErP because they are considered as exhaust towers.

A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine.

I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents. I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.

When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream; and, as I lie close to the earth, a thousand unknown plants are noticed by me: when I hear the buzz of the little world among the stalks, and grow familiar with the countless indescribable forms of the insects and flies, then I feel the presence of the Almighty, who formed us in his own image.
