APRFD

APRFD

EXTRA HIGH-PRESSURE CENTRIFUGAL FAN 

High efficiency reverse-blade impellers. Double stage, with connection duct.

Double-extension motor, directly coupled.


Use: for the suction of clean and dusty air. These types of fans with doubles stage, are characterized by a high out put which allows a certain saving of electric power; by using special types of fan wheels with inverted blades (negative).
They are used for giving oxygen to impure waters, for pneumatic conveyalces, in cement factories, in the mills, in “pasta” factories, in dye works (for the quick drying wool), in ceramic factories (for the pneumatic cleaning of the rooms), in chemical, iron and metallurgical industries where small and medium capacities with very high pressure are required.

The temperature of the fluid sucked in must not exceed 80°C.

Characteristics:   V = 1.080÷12.000 m3/h    |     Pt = 1.400÷5.000 kg/m2


ErP: these fans are covered by Directive 2009/125/EC. Series APRED-APRFD-APRGD always have a specific ratio greater than 1.11. Please note that in the case of specific ratio >1,11 the Directive 2009/125/CE is applied, but these fans are not subject to the constraints of energy efficiency that it impose and therefore neither to the verification of these parameters.

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.
