Prior to the installation of a Transair® compressed air
distribution system, the installer should ensure that the
installation area complies with any regulations applicable
to areas exposed to explosive hazards (in particular
the effect of static electricity in a silo area). Transair®
should be installed downstream of the compressed air
receiver, or after the dryer. Flexible Transair® hose can be
installed at the start of the system in order to eliminate
any sources of vibration and to facilitate maintenance
operations. When maintaining or modifying a Transair®
system, the relevant section should be vented prior
to the commencement of any work. Installers should
use only Transair® components and accessories, in
particular Transair® pipe clips and fixture clamps. The
technical properties of the Transair® components, as
described in the Transair catalog, must be respected.
Pressurizing the System
Once the Transair® installation has been installed and
prior to pressurizing, the installer should complete
all tests, inspections and compliance checks as
stated in any contract and according to sound
engineering practice and current local regulations.
Transair® Pipe and Hoses
Transair® pipe should be protected from mechanical impact,
particularly if exposed to collision with fork-lift trucks
or when sited in an environment with moving overhead
loads. Similarly, rotation of the pipe and pipe supports
should be avoided.Transair pipe must not be welded.
Flexible Transair hoses should be used in accordance
with the recommendations of the installation guidelines.
Expansion and contraction of the system should be
calculated prior to installation. The system designer
and installer should calculate the elongation or
retraction of each Transair line according to the
recommendations in this installation guide.
Transair® components are provided with assembly
instructions for their correct use - simply follow the
methods and recommendations stated in this document.
Transair® Installations - Situations to Avoid
■ Installation within a solid mass (concrete, foam, etc.)
■ The hanging of any external equipment to Transair pipe
■ The use of Transair for grounding, or as a support for
■ Exposure to chemicals that are incompatible
with Transair components (please contact mdi for further details)
Sound engineering practice for the optimization of an air pipe system
■ When installing a Transair system, the
work should be performed in accordance
with good engineering practice.
■ Bends and bypasses represent sources of pressure
drop. To avoid excessive pressure loss, use modular
consoles to offset the network and to bypass obstacles.
Keep in-line pipe diameter reductions to a minimum.
■ Maintain a consistent level of good quality air by use
of adequate filtration at the compressor outlet.
■ The diameter of the pipe will influence pressure drop
and the operation of point-of-use equipment. Select
the diameter according to the required flow rate and
acceptable pressure drop at the point of use.
■ Position drops should be as close as
possible to the point of use.
Transair® Pipe Size Selector
Select the Transair® pipe diameter for your application based on required flow against pressure drop.
Estimated values: Closed loop system at 100 PSI with 5% pressure drop.
Transair’s innovative technology enables rapid and easy assembly with
quick connection of components to the aluminum pipe. This technology
takes into account the specific requirements of each diameter and provides
the user with an optimum safety coefficient and easy connection.
Pipe-to-pipe and male connectors in
Ø 1/2", Ø 1" and Ø 1 1/2" can be
immediately connected to Transair pipe –
simply push the pipe into the connector
up to the connection mark. The gripping
ring of each fitting is then automatically
secured and the connection is safe.
Pipe-to-pipe and male connectors in Ø 2"
and Ø 2 1/2" can be quickly connected
to Transair aluminum pipe by means of
a snap ring. This secures the connection
between the nut and the pipe – tightening
of the nuts secures the final assembly.
Pipe-to-pipe and male connectors in
Ø 3", Ø 4" and Ø 6" can be quickly
connected to Transair aluminum pipe.
Position the pipes to be connected
within a Transair cartridge and close/
tighten a Transair clamp.
