Capacity Gauge
Used in rotary screw compressors, a capacity gauge is a device that provides a visual indication of the compressor’s output — measuring the amount of airflow the machine delivers at any given time. This air compressor gauge measures airflow as a percentage of the compressor’s rated capacity on a scale of zero to 100%.
A capacity gauge provides real-time feedback on the compressor’s performance and efficiency in relation to its maximum potential output. This is especially important for rotary screw compressors due to their continuous operation, ensuring a consistent supply of compressed air for various applications.
FAQs
A capacity gauge is particularly beneficial for rotary screw compressors for several reasons:
- Continuous operation: Unlike reciprocating compressors that cycle on and off, rotary screw air compressors are designed for continuous operation. A capacity gauge allows operators to ensure the compressor delivers the expected volume of compressed air to meet an application’s needs.
- Monitoring performance: A capacity gauge helps operators monitor airflow when running at or near full capacity. This ability aids in optimizing the compressor’s performance and allows you to make adjustments to optimize efficiency without wasting energy.
- Troubleshooting: A sudden drop in the capacity gauge reading allows users to identify potential maintenance issues. Reduced airflow could indicate a problem with the system, such as a clogged filter, a leak, worn components or excessive demand. Quincy Compressor provides maintenance solutions that can improve equipment uptime and energy efficiency.
- Sizing considerations: Measuring airflow helps you select the right size compressor to adequately power your air tools and applications. An undersized compressor may struggle to keep up, while an oversized unit may cycle unnecessarily, leading to wasted energy consumption.
The capacity gauge is one of the key instruments typically found on the air compressor’s instrument panel. It utilizes a zero to 100% scale, providing an easy-to-read indication of a compressor’s current airflow capacity.
The circular gauge has small lines that divide the percentage of capacity into increments. To read the gauge, simply look where the needle points on the zero to 100% scale. These numbers measure capacity percentage — not the tank’s volume.
For example, if the needle is at 20%, this indicates that the airflow output is relatively low. If the gauge consistently shows a low percentage, it might mean a smaller compressor would be more suitable for your compressed air needs.

While a capacity gauge measures airflow, the pressure gauge measures the air pressure within the system, typically expressed in pounds per square inch (psi).
There are two main types of pressure gauges, each with a unique purpose:
- Tank gauge: This type measures the pressure of the air stored in the tank, allowing you to understand how long you can run your processes or tools before the compressor needs to refill.
- Regulator gauge: This gauge measures the output air pressure being delivered to your tools. Different tools require different pressures to work effectively without wearing out.
