What pressure do I need for my compressor?

When operating an air compressor, the pressure level at which the compressor is operated will play a critical role in its performance. But plant operators often find it difficult to establish the optimal pressure required within their system. Within this post, our experienced team will explain pressure analysis and outline the methods to ensure a system is operating at the most efficient pressure levels.
Pressure Should be Higher at Compressor Discharge
The pressure at the compressor discharge must be higher than at the point of use within the compressed air system. That’s because the pressure drops through the piping, filters, valve and dryers and will prevent optimal performance if the process isn’t initiated with a high enough pressure level.
Grouping Equipment can Ensure Efficiency in the Right Circumstances
Companies can often save money on their compressed air expenditure by grouping equipment by its required pressure level. This ensures they can create a separate line to high pressure equipment while maintaining low pressure systems at their peak efficiency rates. Firms may also save money by grouping end uses by their air pressure and quality requirements. This helps to minimize flow disruption by reducing the amount of piping, air treatment, and controls between similar end-use points in the system.
Oftentimes, however, this type of arrangement isn’t practical as it requires additional space and further equipment expenditure.
What is the Total Air Requirement?
The total air requirement within the system often dictates the pressure level needed for the compressor. If a significant portion of a company’s systems require 100 psig, it’s often more practical to supply all systems at this level consistently. This helps mitigate pressure and performance losses within the system but may end up costing the company money in terms of energy use.
Effective Measurement and Safeguards can Bring Results
Most manufacturers use a built-in pressure safety margin for their equipment to ensure effective and efficient operations. Operators should regularly review their system’s operating pressure to check it’s at least meeting the minimum requirements. The leading companies now employ alarm systems, which tell them when their compressed air systems deviate outside the safe and effective pressure brand. This helps keep the plant safe and ensures all processes are completed to the highest levels of efficiency.
By learning about the recommended pressure levels for their air compressors, plant operators can ensure high energy efficiency in the long-term. To learn more on how to manage pressure levels within a compressed air system, speak with our team today!
