Size considerations

  • A common error we see in compressed air systems, in addition to poor piping practice, is line sizes too small for the desired air flow. Small piping exacerbates poor piping practices by increasing velocity- and turbulence-induced back pressure.
  • Pipe size and layout design are the most important variables in moving air from the compressor to the point of use. Poor systems not only consume significant energy dollars, but also degrade productivity and quality. The objective in sizing interconnecting piping is to transport the maximum expected volumetric flow from the compressor discharge, through the dryers, filters and receivers, to the main distribution header with minimum pressure drop. Contemporary designs that consider the true cost of compressed air target a total pressure drop of less than 3 psi.

Installation costs

  • The materials and modular design of a Transair air quick connection pipe system makes it easier and less expensive to install than traditional systems. Its aluminum piping is easier to lift and handle than standard steel piping, and its push-to-connect fittings secure connections with a simple push and twist. The fittings eliminate the need for special tools, pipe preparation and threading. The use of Transair also eliminates the time needed for soldering and glue drying. And once the pipe is pushed into the fittings, the connections secure and ready to be pressurized.

  • Labor accounts for 20 percent of the cost of installing an aluminum piping system. By comparison, labor accounts for 60 to 80 percent of a steel system, 50 to 70 percent of a copper system and 40 to 60 percent of a plastic system.


Installation instructions

  • Transair compressed air pipe systems are quick to install and ready for immediate pressurization. No particular preparation (cutting, deburring, chamfering, etc.) is required. Transair aluminum pipe is calibrated and fits perfectly with all Transair components. Each connection is automatically secured and the seal is optimized. Components are removable and interchangeable and allow immediate and easy layout modifications. All components incorporate quick assembly connection that enables Transair systems to be assembled much more quickly than galvanized steel or copper system.

  • 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.

Variables to consider

  • Successful operations need to be able to take advantage of new equipment options and automation techniques without incurring lengthy downtime and expense. Consequently, the ability to reconfigure production layouts or implement process changes quickly is critical. Transair makes reconfiguration practical and efficient. Because Transair’s fittings are not soldered or glued, the components are reusable and can be removed and reinstalled. The modular design and handling ease enable plant personnel to implement many layout changes within minutes, not hours. This minimizes downtime and increases plant productivity. Furthermore, the flexible hose used in a Transair pipe system eliminates many of the layout constraints encountered with rigid piping systems such as physical obstacles.


Energy savings

  • Energy costs associated with a compressed air system are significant. For example, when analyzed over a ten-year period, the cost of energy consumed by an average compressed air system exceeded other costs, including the initial cost of equipment and installation. The cost of electric may exceed the cost of the capital equipment, each year! System pressure drops are one cause of inefficient energy use. A 14.5 psi pressure drop uses 10 percent additional energy. These drops can result from a number of sources, including poor system configuration, interior pipe surface corrosion, and compressed air contamination.

System Configuration

  • Poor system configuration can lead to improper airflow. The flexible hose used in Transair aluminum piping system eliminates many of the layout constraints encountered with rigid piping systems. It accommodates physical obstacles and provides a link between the compressor and piping.


  •  Interior pipe corrosion is a common cause of pressure drops and higher maintenance costs. Smooth bore piping, such as plastic and aluminum, resist corrosion. Galvanized and black iron pipe decreases in opening over time. Galvanized and black iron fittings are crudely designed with restrictions to air flow internally. Brass and copper fittings and valves typically have smaller bores than the associated pipe size. Transair pipe will not corrode and the fittings are ALL designed for compressed air flow with full bore construction.

Durable protection of equipment

  • Transair enables elimination of the problem of rust, usually associated with steel air pipe systems. It guarantees the complete absence of corrosion (self protection by formation of aluminum oxide). The inner surface of aluminum pipe ensures good and constant quality clean air continuously.

  • Transair also protects industrial equipment against water deterioration thanks to its quick assembly brackets with integral upward loop.

  • Compressing ambient air to the discharge pressure introduces moisture into supplied air. Unfortunately, aftercoolers, filters, and dryers do not completely eliminate moisture and its destructive results. As a result, steel pipe systems will begin to rust and corrode, thereby inhibiting smooth airflow and reducing system pressure.

  • Pipe corrosion also increases compressed air system maintenance. Steel pipe systems need to be dismantled and inspected to monitor corrosion build up. Not only does replacing corroded pipe interfere with production, it causes rust, corrosion and other particles to be released into the air system, thereby causing instrument, valve, tool and machine operation problems or damage with the resultant downtime.

Air contamination

  • Air cleanliness is another factor that affects consistent airflow. Dirt and dust particles passing through the piping system are gradually deposited on the interior surface of piping. As these deposits accumulate, friction increases and system pressure decreases. Black iron and galvanized steel piping systems are more prone to build-up than stainless steel. Meanwhile, smooth bore piping materials, such as Transair aluminum pipe, offer more resistance to deposit build-ups.

Air leaks

  • Inherent in threaded steel piping systems, non productive leaks also waste compressed air, thus electrical energy and your dollars. Difficult to trace and repair, they can have a huge impact on operating budgets. A typical threaded compressed air system leaks 35% of its volume, that’s one third of the electrical bill associated with compressed air! With its bubble-tight seals, pipe and push to connect fittings will eliminate compressed air leaks and lower your electrical costs associated with the production of compressed air.

Transair Liquid Piping Solutions

 In addition to our innovative line of air and inert gas piping products, Transair offers a complete line of liquid piping solutions. Due to its reusable connection technology, Transair is the only pipe distribution system for fluids with the ability to quickly install and adapt. The connection is simply screwed or bolted together, which enables disassembly when required unlike other connection technologies that are permanently crimpled or welded.

Transair Pipe Sizes

The innovative technology of Transair enables rapid and easy assembly: quick connection of components to the stainless steel pipe. This technology takes into account the specific requirements of each diameter and provides the user with an optimum safety coefficient and easy connection. Transair provides a fast, easy, clean and reliable means for installing 22 mm (½”), 28 mm (¾), 42 mm (1 ¼”), 60 mm (2”), 76 mm (3”) and 101 mm (4 ”) stainless piping systems.
