General
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/Contraction
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.

Component assembly
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 electrical equipment
■ 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.
