In many companies, compressed air systems are among the largest consumers of electricity. However, not everyone realizes that this consumption can be significantly reduced—and without major investment. In this article, we'll show you how much energy a typical compressor consumes and how to realistically reduce its operating costs.
1. What does the power consumption of a compressor depend on?
The amount of energy consumed is influenced by several factors:
Compressor type – screw compressor works more efficiently and more stably than piston compressor.
Motor power – the higher the power, the higher the current consumption (but also the faster the pressure build-up).
Operating mode – continuous vs. intermittent operation (with long stops).
Technical condition of the device – dirty filters, leaks and worn-out components increase energy demand.
Air quality in the system – moisture and impurities reduce efficiency.
2. Example of electricity consumption – how much does it cost?
Let's take a simple example:
🔧 7,5 kW screw compressor , working 8 hours a day, 5 days a week (average load: 75%).
Calculation:
7,5 kW × 8 h × 5 days × 4 weeks × 0,75 = 900 kWh per month
With the price of energy 1,20 PLN/kWh it gives PLN 1080 per month just for powering the compressor.
And that's just one machine.
3. How to reduce energy costs when operating a compressor?
✅ Take care of the tightness of the installation
Leaks are the most common and costly problem. Even a 10% air leak can add hundreds of zlotys to your monthly bill.
🔧 Czemar.pl offers compressed air audits that allow you to precisely locate and eliminate losses.
✅ Regular maintenance and clean filters
Dirty filters, worn valves or low pressure in the system mean that the compressor has to work longer to achieve the required parameters.
Solution: Service at least every 6 months. We offer both inspections and general overhauls of compressors.
✅ Use an inverter
Modern inverter compressors adapt their operation to current demand – which significantly reduces power consumption.
In many cases, this allows you to reduce energy costs by up to 30–40%!
✅ Choose the right compressor
Sometimes the biggest problem is… a compressor that's too large. A well-selected unit uses less electricity and reaches the desired pressure faster.

4. Is it worth investing in energy-saving solutions?
Yes – especially if the compressor runs daily, for several hours a day, or for an entire shift. The return on investment in a better model, an inverter, or an energy audit can be seen in just a few months.
