Selecting the appropriate air compressor for an enterprise is a complex and time-consuming process, especially if you are unsure what factors to consider during selection. The correct choice directly impacts not only production processes and product quality but also energy efficiency and cost reduction.
In this blog, we will pose questions that will guide you in choosing a compressor.
What is the purpose of using the compressor?
First and foremost, you must precisely define the purpose for which you need to purchase a compressor. At this stage, you are not merely acquiring equipment; you are making a significant decision directly linked to your enterprise’s operations, revenue, and expenses. A clearly defined purpose is a fundamental step toward making an effective, economical, and reliable decision.
What type of compressor is needed?
Next, you need to determine the type of compressor required for your application.
Do you need a compressor for a small workshop? Or for large industrial processes? Does air quality matter? Oil-free or oil-lubricated? This decision depends on your industry, as different applications require different types of technology. For example, oil-free air compressors are used in hospitals or food production. Perhaps you need to clarify whether to choose a rotary screw or a piston compressor? (You can find advice in our blog: Rotary Screw or Piston Compressor?)
Whatever your needs, at AIESKO you will find suitable air compressors for any industry, whether it’s rotary screw, oil-free rotary screw, oil-free scroll, oil-free turbo, or mobile compressors.
What are the specific air and pressure requirements?
When selecting, it is crucial to determine the air flow rate, volume, and pressure.
Air flow rate describes the speed of air movement at a single point, while air flow volume describes how much air volume passes through a channel per unit of time.
To measure compressed air flow rate, cubic meters per minute (m³/min), cubic meters per hour (m³/h), or liters per minute (L/min) are typically used.
When measuring air pressure, you will often encounter the use of three primary units: kPa, bar, and PSI. For technical or engineering calculations where precision is important, use kPa or bar.
kPa (kilopascal) – The international SI unit. Used in technical and scientific fields. 1 kPa = 1000 Pascals. For example, the internal pressure of a compressor can be 600 kPa.
Bar – Most common in Europe, a simple measure for industrial equipment. 1 bar ≈ 100 kPa.
This information will help you determine the appropriate size and power of the compressor, making it easier to answer the following questions:
What is the compressor size?
The correct compressor size depends on the task to be performed. If you choose a small compressor, it will not be able to handle the existing task, while if you choose one that is larger than necessary, it will consume excess energy and may cause mechanical problems. Regardless of whether you are upgrading an old unit or creating a new air system, determining the precise compressor size requires actual data, not assumptions. As mentioned, to answer this question, you must have determined the air flow rate, volume, and pressure; otherwise, selecting the exact size will be quite difficult. Our specialists will simplify this process for you by conducting an air system audit to measure your actual requirements.
What is the compressor’s power?
When selecting compressor power, it is important to consider not only the required air pressure, speed, and flow but also the operating mode and power supply conditions.
If the compressor operates intensively and continuously, it is essential to select an industrial, rotary screw type model designed for prolonged loads. Furthermore, when choosing the power, consider the availability of electricity and grid capacity in the enterprise to ensure stable compressor operation and prevent motor overload or extended downtime.
What space is allocated for the compressor?
Try to find an air compressor that will be suitable for its designated space. Some compressors require a separate station, while others can be installed directly in the production area. You should also consider the cooling and ventilation conditions in the spaces allocated for the equipment.
To provide a comprehensive answer to the question, pay attention to:
Power source – First, confirm whether you have the appropriate electricity (voltage).
Noise level – Perhaps you need a quiet model for your working environment? Clarify the noise level. Check the noise level of the selected compressor and ensure it complies with regulations and occupational safety standards.
Working environment – Based on the placement location, you will determine which equipment you need, portable or stationary.
How energy-efficient is the unit?
Energy efficiency is essential for reducing operating costs. Moreover, energy efficiency represents a significant component of the total lifecycle cost of an air compressor. Choose a model that meets environmental regulations and supports sustainable development goals. In this section, it is important to remember that variable frequency drives for air compressors exist, which will contribute to the energy efficiency of your chosen compressor.
You can find additional information about the benefits of energy efficiency in our blog: Energy-Efficient Compressor as a Tool for Saving Operational Costs.
What are the necessary components?
Many facilities use additional equipment to meet specific needs.
The AIESKO team will help you select and purchase appropriate additional equipment and spare parts if needed. We offer: air dryers, blowers, piping, storage tanks (reservoirs), electric motors, variable frequency drives, and spare parts, such as bearings, separators, oils, filters, thermostats, belts, etc.
What is the total cost of ownership?
The total cost of ownership includes not only the initial purchase price but also operating costs, energy consumption, and service and maintenance expenses. A more expensive model may provide relatively lower operating costs and better long-term efficiency. Therefore, you need to understand the compressor’s maintenance and service requirements. Some models require more frequent maintenance than others. Consider the availability of parts and service options and choose a model that aligns with your maintenance capabilities and schedule.
At this point, many might think that reducing or postponing service will cause no harm, but to better consider this, read our blog: Compressor Service and Its Necessity.
AIESKO’s highly qualified team of technicians is available 24/7 to assist you, whether for a simple consultation or emergency service (you can find our services at the link: AIESKO Services.
Whom do you trust as a supplier and why?
A compressor is a long-term investment, and the correctly chosen supplier plays a huge role in its acquisition. For the continuity of your production process, it is essential that the supplier is reliable, trustworthy, experienced, and always ready to assist you.
Remember, the quality and longevity of the equipment, and the stable operation of your business, depend on the supplier’s reliability, so ensure you are making the right decision in this regard.
