Manifolds

Comprehensive Guide to Selecting Manifolds and Air Splitters for Compressed Air Systems 

Manifolds (wall or bar) and air splitters are essential components in compressed air systems. They divide a single compressed air airline into multiple branches, enabling compressed air distribution to various tools, machines, or workstations within a facility. They serve as centralized points where multiple connections can be made, allowing for efficient and organized compressed air distribution. 

By considering the factors (below) comprehensively, you can select a manifold and its associated components that meet the specific requirements of each drop in your compressed air system, ensuring efficient operation, durability, and compatibility with your application’s needs. 

Number of Ports Required: 

Determine the number of ports needed on the manifold based on the connections required for your compressed air tools, equipment, or workstations. Consider current needs as well as potential future expansions. Ports can be blocked with a plug if/when not in use. 

Drain or No Drain: 

Assess the moisture levels in your compressed air system. In environments with high humidity or where moisture buildup is shared, opt for a manifold with a drain feature to prevent condensate accumulation, which can lead to corrosion and malfunction of pneumatic equipment. 

Material and Environment: 

Consider the environmental conditions of your application, such as temperature, humidity, presence of corrosive substances, and exposure to outdoor elements. Choose a manifold from materials resistant to corrosion and degradation, such as aluminum, to ensure longevity and reliable performance in the given environment. Similarly, select quick couplers made from durable materials that withstand the same environmental factors. 

Matching SCFM Requirements: 

Some manifolds come assembled with one or more quick couplers. To select the proper assembly, determine the SCFM requirements of your pneumatic tools and equipment. The manufacturer typically provides this information, which can also be calculated based on the tool’s air consumption rate. Choose a quick coupler size that can accommodate the required SCFM to ensure the proper operation of your tools. 

Frequency of Use and Tool Variety: 

Assess the frequency of use of your pneumatic tools or components that will be plugged into the manifold. Consider whether there will be variations in tool usage or if additional tools may be added. For example, if a tool needs to be plugged or unplugged from a manifold multiple times per day, choosing a quick coupler that allows for one-handed disconnection, or zer-pressure disconnection should be prioritized. 

Port Configuration: 

Consider the layout and arrangement of ports on the manifold to ensure compatibility with your compressed air system and the positioning of tools or equipment. Choose a manifold or air splitter with a port configuration that allows for easy access and connection of pneumatic devices, considering any space constraints or installation requirements. 

Requirement for Ball Valve: 

Determine if you require ball valves for individual control over airflow to each manifold in your system. Ball valves provide a convenient way to shut off airflow to specific ports when not in use, reducing energy consumption and preventing leaks. Assess whether the added control and convenience of ball valves are necessary for your application.
