Lowering power consumption and accurately measuring leaks, among other best practices, can help keep compressors working efficiently. Here are 10 tips to implement for your compressors.


1. Lower the Pressure

Each additional pound of pressure could increase power consumption by 7%.



2. Save on Cleaning

Consider a dedicated low-pressure air compressor and air line for cleaning to save power.



3. Consider a Variable Frequency Drive

Screw compressors should run under full load. If the usage pattern varies, consider a variable frequency drive (VFD) for up to 35 percent in energy-cost reduction.


4. Size Matters

Identify the right-sized compressor for the requirement. An oversized compressor will run on unload mode, leading to higher power consumption.



5. Air Audit

An air audit could help save millions in the budget by checking the efficiency of the compressed air system.


6. On-Time Service

Delaying an air filter change will increase the compressor’s power consumption. Schedule on-time service for optimal power consumption.

7. Quarterly Checks

Perform quarterly checks for leaks in the compressed air circuit.


8. Calibrate Gauges

Calibrate the pressure gauges at quarterly intervals to accurately measure leaks.

9. Dryer Sizing

Identify the right-sized dryer for the requirement. An oversized dryer will consume more power.


10. Pre-Filters

Install pre-filters for suction air and cooling air to extend the life of the compressor and its consumables.
