Two types of manufacture :
Choice of color: Black, gray or white.
* On request the interior spiral is manufactured out of stainless
steel or galvanized..
Applications :
Two products :
-
AEROFLEX PLUS - STANDARD :
Ventilation air conditioning in construction bound for the individual
and grouped habitat, the offices and the trade. Dust extraction equipment
in industry, Systems of diffusion of hot and cold air, gas, the vapors...
-
AEROFLEX PLUS - NOT-FLAMMABLE :
Product made out of matters not-flammable (MO). Ventilation in particular
in the workshops of welding. Systems of de-dusting of grinding machines,
evacuation of polluted air of vapors and aggressive gases. Non flammable
super quality is certified by "VERITAS" for its application
in the construction of ships.
Characteristics :
Air conditioning and de-dusting, of many advantages :
-
Extreme flexibility with its radius of curvature
equal to the 2/3 of its internal diameter,
-
Excellent handiness and adaptability allowing
a diversity of configuration of installation, the pipe preserving
its nominal diameter,
- Easy bending with the hand, it can preserve the form given,
-
Very good absorption of the vibrations,
- Amplitude of temperature : :
- -25°C à + 75°C pour l'aeroflex-standard.
- - 40°C à + 150°C pour l'aeroflex not-flammable
-
Extra-light : 1 m/l, Ø 80 mm = 600g
-
-
Easy of employment, handling and transport.
The use of AEROFLEX MORE ensures perfectly :
-
The air conditioning, without loss,
-
The absortîon of the vibrations of the installation,
-
The aspiration of the vapors and aggressive gases.

PRESSURE LOSS (*)
Example of calculation for right tubes :
For an internal diameter 180 mm, a 1,6 m length and a
flow of 500 mVh, either a pressure loss of 3 X 1,6 or 4,8 Pa.
In this example the pressure loss will be 3 Pa per flexible meter of tube.
Example of calculation for curved tubes :
The mode of calculation of the pressure loss implies
the determination preliminary fictitious length of the tube curved to
the diameter are equivalent the pressure loss will be identical to that
of the ray in question.
In the event of change of direction of 90°, this table highlights
