How to Network Two Air Compressors Together

In heavy-duty industrial applications where operations are continuous and demands for compressed air occasionally fluctuate, more than one air compressor is required. The most evident solution is to upgrade to larger compressors. However, it also makes sense to network two air compressors together. 

Connecting two air compressors can replicate the effect of a more powerful tank. They are also more mobile and portable in cases where your application requires constant transport. 

So, if you want to maximise your compressors’ output, this article will guide you through connecting two air compressors. 

Understanding the Basics of Air Compressor Networking

Air compressor networking is simply connecting two units to work together. It requires various elements, such as valves, air hoses, and switches. This air compressor technique is performed for these main reasons: 

• Load Sharing: To balance workload and prevent overuse. 
• Redundancy: To ensure uninterrupted air supply by having a backup. 

Other than these reasons, various benefits come from connecting two air compressors. Know about these below.

Benefits of Connecting Two Compressors

• Increased air supply for high-demand applications.
• It becomes more reliable as one can take over if the other fails. 
• Energy wastage is reduced, prolonging the life of critical air compressor parts like motors and valves. 

Types of Air Compressor Setups

Sequential Setup

The sequential setup initially operates only one compressor, letting the second kick in when demand increases. This setup is suitable for applications with changing air needs. 

Parallel Setup

If you need both compressors to share the load due to high demands and heavy-duty applications, you can opt for a parallel setup that runs two compressors simultaneously. 

Lead-Lag System

In a lead-lag setup, there is a designated central compressor and backup, which means the backup will only work once the demand rises or if the primary unit fails. This type of setup is perfect for businesses that need enhanced reliability while maintaining low energy usage. 

Step-by-Step Guide to Network Two Air Compressors

Step 1: Assess Compressor Compatibility

Whether you’re connecting a piston compressor, belt-drive air compressor, or another air compressor type, it’s critical to ensure compatibility. The two air compressors should have matching pressure ranges and output capacities, as a mismatch could lead to system failure. 

Step 2: Choose the Right Setup

Assess your operational requirements and select a setup that will suit your needs. To better understand what you’ll need, you can check the different types of air compressor setups. 

Step 3: Prepare Your Tools

To ensure a smooth process of connecting the air compressor, you must have the following tools and accessories: T-fitting, check valves, regulator, gauge, switches, unloader valve, outlet, air manifold, and airline. 

Step 4: Install Check Valves and Air Receiver Tank

Start connecting your air compressors. Install check valves in each compressor to prevent backflow and ensure air can’t flow across them. You can also install an air receiver tank to help stabilise airflow and store excess air. 

Step 5: Connect Pressure Switches and Controllers

After connecting the compressors, you should install a pressure switch and controllers on both air compressors to synchronise them. These tools will ensure that operations are coordinated and switching and load sharing will become seamless.  

Step 6: Test the System

Run a system check to review potential leaks. This testing can also tell you if the compressor works seamlessly and can already meet the required air demand for your applications.

Maintenance Tips for Networked Compressors

To ensure that your networked air compressor will have a longer lifespan, you have to follow some of these maintenance tips: 

• Regular Inspections: Check your air compressor’s connections, valves, and controllers for possible wear and tear so you can promptly address the issue. 
• Monitor Performance: This monitoring will tell you if the compressor is still optimal for usage. Specifically, check for pressure stability and energy consumption. 
• Adjustments and Troubleshooting: If you notice a slight change in cycling and pressure, inspect the setup immediately and perform basic troubleshooting. 

Maximising Efficiency with Networked Air Compressors

Following the outlined steps, you can adequately connect two air compressors and experience their numerous benefits, like reliability, energy efficiency, and better air supply.
