Select the Transair
®
diameter for your application
based on required flow and pressure drop.
1 • Areas of application
Before installing
Transair
®
, a responsible person should check that the
area of installation conforms to regulations designed to prevent the risk
of explosion (in par ticular the risks associated within silo zones)
Transair
®
must be installed either after the air receiver or after the dryer.
Flexible
Transair
®
hose should be fitted at the beginning of the pipe
system, in order to counter the vibrations found in any compressed air
system. When maintaining or modifying the
Transair
®
pipe system the
work must be under taken only after the compressed air system has been
vented. The installer must use only
Transair
®
components and accesso-
ries, and in par ticular,
Transair
®
fixing clips. No other type of fixing
method is to be used. The technical characteristics of
Transair
®
compo-
nents as expressed in this catalogue must be respected.
2 • Starting the installed system
Once assembled, the operation of the
Transair
®
installation is the responsibili-
ty of the installer who, prior to use, must complete all necessary tests.
The installer must also ensure that the installation has been properly carried
out in line with the instructions and that it meets all legal requirements.
3 • Transair
®
pipe
Care should be taken to protect pipes against mechanical shocks – especially
when close to the passage of fork-lift trucks or where suspended objects are
being moved. Equally all excessive rotational movements which could lead to
disconnection, whether on the pipes or the suppor ts, must be avoided.
Transair
®
rigid pipes must not be bent (formed) or welded. Flexible
Transair
®
hose must be used in accordance with the instructions in this catalogue.
4 • Contraction/expansion
The per formance of the
Transair
®
system is maintained when the ef fects
of expansion or contraction are properly taken into account.
5 • Assembling the components
To ensure proper installation
Transair
®
components are supplied with an
"Assembly Guide". The installer must follow with care the precise
instructions as described in this guide as well as this catalogue
6 • Supports
When suspending from a ceiling
Transair
®
clips should be fixed to a rigid
suppor t (U channel, cable tray, threaded rod, etc).
This type of suppor t ensures that the clips stay in alignment which allows the
pipe to expand and contract.
7 • Observations
When using
Transair
®
the following situations must be avoided :
• embedded in a solid mass (concrete, injected foam)
• fixing other external elements to
Transair
®
pipe (other than
• blowguns, plastic tubes etc with a maximum weight of 20 kgs
between 2 clips).
• the use of
Transair
®
as an electric ear thing or to suppor t
electrical material.
• the use of
Transair
®
with non-compatible components.
