Consider the following things before you purchase anything:
1. What Compressor size do I need?
The very first step of choosing a air compressor is to understand what size compressor you need. The correct size of a compressor depends on the task means to perform. Pick one is too small and it wont get it job done. Choose one it is too large, and it will waste energy and could lead mechanical problems. Correctly sizing your compressor requires real data about your needs, not guesswork. Whether youre upgrading your current compressor or designing a new system, ask a compressed air sales professional to conduct an air system audit to measure your actual demand.
If youre planning for future capacity, keep in mind that a compressor should be sized to address actual demand. Instead of anticipating potential future demand by oversizing today, add a compressor when the time comes to provide flexibility and redundancy as your operation expands. Also keep in mind that process improvements often reduce air demand; you may be able to expand your operation without expanding air production.
2. What type of compressor do I need?
The next thing to do is to decide on the type of compressor you need for your application.
There are two main types of compressors, piston compressor and rotary screw compressor. Piston compressor which are sometimes also called reciprocating air compressors, are the most economical and least expensive air compressors available. Rotary screw compressors are often the ideal choice for operations that require a constant compressed air supply.
3. Does air quality matter? Oil-Free Or Oil-Lubricated?
Generally, there are two basic categories of air compressors; oil-free or oil-lubricated. Oil-free air compressors dont use oil and can help you ensure that your air quality is great. These are ideal for facilities where air quality is extremely important. On the other hand, oil-lubricated air compressors use oil to lubricate their parts. These machines are incredibly energy-efficient. Take some time to reflect on which type you prefer more.
To not overcomplicate the answer, your choice should be based on the application and process that the compressed air will be utilized in.
4. Understand the pressure and flow?
Compressed air flow is typically measured in cubic meter per minute (M3/min). Compressed air pressure is typically measured in pounds per square inch (Kpa) or barg. Think of flow as the ability to perform a process within an acceptable time frame, and pressure as the ability to support multiple processes at once.
5. Whats The Duty Cycle?
An air compressors duty cycle refers to how often the machine will run. Different models will have different cycles, which could affect your facilitys work.
6. How Much Space Will It Take?
Smartly using your available space is crucial if you want to stay organised and productive. Think about how much space you have allotted for commercial air compressors and try to find an air compressor that will be suitable for your worksite.
7. How Will It Be Installed?
Think about how your air compressor will be installed once youve purchased it. Will you install and set it up yourself, or will you hire someone else to do it? You should also consider how your product will be delivered and, if you are replacing an old one, how you will remove your old air compressor.
8. How Will It Be Maintained?
Always figure out the best way to maintain your new air compressor before you order it. Factor in the long-term maintenance cost if you are working on a tight budget. Good air compressors work well and arent a pain to maintain, so knowing how to take care of your air compressor before you have it is a good idea.
After you purchase and receive your air compressor, remember to maintain and check it routinely. Well-maintained air compressors are less likely to break down than neglected ones and will last longer.
9. Initial vs. Overall Cost
When considering an air compressor, a primary concern should be: How can I get the most amount of compressed air for the lowest overall cost? Many consumers may consider only a small fraction of the life-cycle cost primarily the initial cost of the machine, not realizing they will likely spend more in electricity the first year to run the machine than the purchasing price. Thats why, when comparing compressors, its important you examine all aspects of the costs associated!
10. Not Sure Where To Begin?
Start by analyzing your air systems life-cycle costs! You can analyze your usage and potential cost savings by conducting a no-contact compressed air energy assessment. Best of all - it causes no harm or downtime to check.
Finally, its absolutely essential that you only buy your new air compressor from a reliable seller. Purchasing important products from companies who dont care about quality can land you in hot water.
Good sellers will always value the quality of their products and the satisfaction of their clients. So, its vital that you always make sure you are buying from reputable and experienced companies.
A commercial A/C (air conditioning) compressor is a key component of an air conditioning system, primarily found in commercial buildings such as offices, retail spaces, restaurants, hotels, and other large-scale facilities. Its primary function is to compress the refrigerant gas, raising its temperature and pressure before it is sent through the condenser coil to release its heat and convert it into a liquid state.
The compressor effectively plays the role of the heart in the air conditioning system, pumping refrigerant through the system. A motor powers it and has two sides: a suction side, where the refrigerant gas enters from the evaporator, and a discharge side, where the compressed, hot refrigerant gas exits and moves towards the condenser.
Commercial A/C compressors are typically more powerful than residential ones, as they're required to cool larger spaces. They come in various types, including reciprocating, screw, scroll, and centrifugal compressors, each offering different efficiencies, costs, and suitable applications. The performance and efficiency of a commercial A/C compressor can significantly impact the energy use and operating costs of a building.
How do A/C Compressors Work?
Commercial air conditioning (A/C) compressors work as part of a larger HVAC (Heating, Ventilation, and Air Conditioning) system to cool and maintain comfortable conditions in commercial spaces. The process involves a continuous cycle of refrigerant gas conversion, which consists of four primary stages: evaporation, compression, condensation, and expansion:
Evaporation
: In this stage, the refrigerant enters the evaporator coil as a low-pressure liquid. As indoor air is blown over the evaporator coils, the refrigerant absorbs heat from the air and evaporates into a gas. This cooled air is then distributed throughout the building.
Compression
: The now low-pressure refrigerant gas is drawn into the compressor, which is typically located in the system's outdoor unit. The compressor's function is to pressurize this gas, which increases its temperature significantly this process transforms the refrigerant into a high-pressure, high-temperature gas.
Condensation
: This hot, high-pressure refrigerant gas then flows into the condenser coils. As outdoor air is blown over these coils, the refrigerant releases heat to the outside and cools down, condensing back into a high-pressure liquid.
Expansion
: The high-pressure liquid refrigerant then moves through the expansion valve, where its pressure is abruptly decreased. This process causes the refrigerant to cool significantly, becoming a low-pressure liquid. This liquid then enters the evaporator coil, and the cycle repeats.
The A/C compressor is the heart of this process, propelling the refrigerant through each stage. Without the compressor, the refrigerant would not move through the system, and the heat transfer process necessary for cooling the building would not occur.
Commercial air conditioning (A/C) systems can utilize several types of compressors, each with different characteristics, efficiencies, and costs. These are some of the most common types of commercial A/C compressors:
Also known as piston compressors, these are similar to a car engine's piston and cylinder system. They draw the refrigerant into a cylinder through a suction valve, then a piston compresses the refrigerant, and it's discharged through an exhaust valve. They are often used in small to medium-sized commercial HVAC systems as they are durable and cost-effective.
Scroll compressors feature two spiral-shaped scroll components. One scroll remains stationary while the other orbits around it, compressing the refrigerant. Scroll compressors are known for their efficiency, reliability, and quiet operation. They are widely used in a variety of applications, from small to large commercial HVAC systems.
These compressors consist of two large helical rotors that compress the refrigerant as they turn in opposite directions. They are known for their durability and efficiency and are typically used in large commercial or industrial HVAC systems that require continuous operation and high capacity.
Centrifugal compressors use a rotating impeller (a kind of rotor) to accelerate the refrigerant, then decelerate it through a diffuser, resulting in increased pressure. They are most effective at high cooling capacities and are ideal for large commercial applications like skyscrapers or industrial processes. Centrifugal compressors are appreciated for their large-scale efficiency, but they can be costly and complex to maintain.
These compressors have a rotor with several blades inserted in radial slots that compress the refrigerant as the rotor turns. They are compact and can provide high sustained air pressure, making them suitable for smaller commercial applications.

Each type of compressor has its advantages and disadvantages, and the choice between them depends on various factors, including the scale of the system, the cooling load, efficiency requirements, noise considerations, and budget.
Choosing a commercial air conditioning (A/C) compressor requires careful consideration of several factors, as it's a vital component that significantly impacts the HVAC system's performance, efficiency, and operating costs. Here are some key factors you should consider:
Size & Cooling Capacity
: The compressor must cool the intended space efficiently. Too small, and it won't cool the space adequately; too large, and it will cool too quickly, leading to frequent on/off cycling, which can wear out the system and lead to uneven cooling. An HVAC professional can perform a load calculation to determine the correct size.
Type of Compressor
: As mentioned earlier, there are various types of compressors reciprocating, scroll, rotary screw, centrifugal, and rotary vane. Each type has its strengths and weaknesses and is suited to different applications. For example, a scroll compressor might be a good fit for a medium-sized office building due to its efficiency and quiet operation. In contrast, a centrifugal compressor might be best for a large skyscraper.
Efficiency
: Higher efficiency units can result in significant energy savings over the system's life, even though they might cost more upfront. The Seasonal Energy Efficiency Ratio (SEER) is commonly used to rate the efficiency of an A/C system a higher SEER rating means greater efficiency.
Durability & Maintenance
: Some compressors are more durable and require less maintenance. However, regular professional maintenance is essential to keep any compressor running effectively and to prolong its lifespan.
Noise Level
: Noise can be a concern, particularly in certain environments. Some compressors, such as scroll compressors, operate more quietly than others.
Cost
: Budget is always a consideration. This includes not only the upfront cost of the compressor but also the cost of installation, maintenance, and operation over its lifetime. An efficient, high-quality compressor may cost more initially but save money in the long run by reducing energy costs and lasting longer.
Compatibility
: The compressor should be compatible with the rest of the HVAC system, including the type of refrigerant used.
Regulations & Standards
: Ensure the compressor meets all applicable regulations and standards in your region, including environmental and energy-efficiency standards.
Generally, it's best to consult a qualified HVAC professional to help choose the suitable compressor for your commercial A/C system. They can consider all these factors and make a recommendation based on your specific needs and circumstances.
Installing a commercial air conditioning (A/C) compressor requires meticulous planning and execution, considering various factors influencing its performance, longevity, and operational efficiency. Here are some key considerations:
Location
: As part of an outdoor unit, the compressor should be installed in a location that's easily accessible for maintenance and repair but also away from high-traffic areas to minimize noise disturbance. It should also be placed in a well-ventilated area and away from direct sunlight, if possible, to prevent overheating.
Proper Sizing
: As mentioned earlier, the compressor's size and cooling capacity should match the building's cooling load. A compressor that's too small or too large can lead to inefficiency, higher energy costs, and shorter equipment lifespan.
Professional Installation
: Commercial A/C compressors are complex and require professional installation to ensure they're installed correctly and safely, comply with all relevant regulations and codes, and operate efficiently.
Ductwork & Insulation
: The ductwork should be well-designed and properly installed to ensure efficient distribution of cooled air. Insulation is also crucial to prevent energy loss.
Electrical Requirements
: The compressor should have a dedicated electrical circuit to handle its power needs, and all electrical work must comply with local codes and standards.
Refrigerant Charge
: The compressor should be correctly charged with the appropriate type and amount of refrigerant. An incorrect refrigerant charge can lead to inefficient operation and potential damage to the compressor.
System Compatibility
: The compressor should be compatible with the other HVAC system components. Compatibility issues can lead to decreased performance and potential system damage.
Climate Considerations
: The type of compressor and its installation may need to be adapted based on the local climate, particularly if the system will be used for both cooling and heating.
Noise & Vibration Damping
: Consider measures to minimize noise and vibration, such as installing the unit on a solid, level surface and using noise-damping mounts or enclosures.
Routine Maintenance Plan
: Regular maintenance is crucial to keep the compressor and the entire HVAC system working efficiently and reliably. Have a plan in place for routine professional inspections and maintenance.
