Vacuum pumps and air compressors both have numerous uses in our homes and transport, as well as in an extensive variety of industrial settings. But what does each one actually do? And what are the key differences between the two? We have put together this guide to help you learn the difference between a vacuum pump and an air pump, and to decide which is the more appropriate solution for you. What Is a Vacuum Pump? As its name suggests, a vacuum pump is a mechanical device that is used to create a vacuum. It does this by moving gas and air out of a system in order to create a secure environment for safely moving or transporting liquids. Although, it is also sometimes used for moving or transporting gases. Vacuum pumps have numerous uses within the home, as well as in various business and industrial environments. For example, you can find vacuum pumps in: Washing machines Cars Aircrafts Air conditioning Irrigation and flood control If liquid has to be moved safely from one environment to another, there is a high probability that a vacuum pump is being used. How Do Vacuum Pumps Work? A vacuum pump creates different levels of pressure within “high” and “low” spaces in the device. Particles flow naturally from a high-pressure environment into a low pressure one so the “high” space empties, causing suction that creates the vacuum. There are several types of vacuum pumps available, which work in different ways: Entrapment Pump: Sometimes known as a trapping pump or capture pump, this uses refrigeration to cool air within a confined space, creating condensation. The liquid can then be removed. Another type of entrapment pump, known as an ion pump, causes condensation by using electrical fields. Diaphragm Pump: Highly accurate and popular for industrial usage, a diaphragm pump uses a pair of mechanical diaphragms, which increase and decrease pressure by moving backwards and forwards. A valve prevents any liquid from escaping. Momentum Transfer Pump: This creates a low-pressure region by using a rotating device to move air or gas from its inlet to its outlet. The vacuum is then sealed by a valve. This type of vacuum pump is also sometimes known as a kinetic pump. Positive Displacement Pump: This has two different cavities, one of which is wider than the other. It creates suction, which provides a steady flow of power. These designs give vacuum pumps a great degree of flexibility, making them ideal for usage in different settings and situations. What Is an Air Compressor? An air compressor pump is a device that takes the energy that’s in air and converts it into power. It does this by putting the air under pressure. The resulting power can be used to operate various machinery and tools. For example, air compressors are used to provide the power for: Home power tools such as drills, nail guns and sanders Brakes for trains and buses Gas station pumps Hydraulic systems Air pumps have such a huge range of applications that they have revolutionised how power can be used in manufacturing. However, they tend to be used to move gases rather than liquids. How Do Air Compressors Work? Air compressors can convert air into power in a number of ways. For this reason, there are several types of air compressor pump variations available: Piston Compressors (Reciprocating): This type of air pump operates similarly to a combustion engine in a car, using a piston within a cylinder. This pumps air into a chamber until the pressure builds sufficiently. Once pressurised, the air can stay within the chamber until it needs to be used. Depending on whether it uses one or both sides of the piston, a reciprocator pump can be single-acting or double-acting. Screw Compressors (Rotary): Rotary pumps, sometimes known as revolving screw pumps, use helical straws to guide the air into a chamber. They provide a continuous flow of pressurised air, making them highly efficient air compressors. They are also quiet to operate. For these reasons, rotary pumps are extremely popular in manufacturing environments. Centrifugal Compressors: This type of compressor uses a rotating impeller to produce a discharge of highly pressurised air. This process is called dynamic displacement. As it allows a continuous flow, it has a higher capacity than some other air compressors. It is also cleaner because all the parts that require oil are positioned at a distance from the airflow. All different types of air compressors have made the process of powering equipment far easier. Air compressors allow each worker in a manufacturing plant to work individually rather than requiring a centralised power source to drive all the tools. What Are the Key Differences Between a Vacuum Pump and an Air Compressor? Vacuum pumps and air compressors are very similar devices that often do similar jobs. However, there are a number of key differences between the two. It is important to understand these if you are choosing the system that’s right for you. 1. Capacity An air compressor has to store pressurised air, so different models have different capacities. Vacuum pumps, on the other hand, are simply moving liquid or gas from one place to another so they do not need a storage capacity. 2. Vacuum Strength The strength of a vacuum pump is measured according to absolute output pressure. The smaller the number, the more powerful the pump is. However, the strength of a compressor is measured by its ability to produce high compression requirements in the fluid. 3. Flow Rate The flow rate of a vacuum pump depends on the pressure at either end of the pump. By contrast, the flow rate of an air compressor depends on its capability for volume reduction. 4. Power Usage A vacuum pump typically requires a lot less power to operate than an air compressor. This means vacuum pumps can be thought of as more efficient. However, this depends on what the pump or compressor is being used for as each will suit different applications.

Compressed air is widely used in everyday life, both in the home and for industrial purposes. Many commercial and industrial companies rely on compressed air as the energy source that powers up pneumatically operated equipment and tools – food manufacturing companies that mix up granular products, aerate liquids and render meat products being just one example. Because compressed air is used for a wide variety of purposes, there are different quality standards of compressed air, with each being suitable for different functions. These quality standards, commonly referenced as ISO 8573-1:2010, are divided into six different classes or levels, which are determined by measuring three contaminants, namely oil content, water vapour and solid particles. Here at Cleveland Compressors, we have a range of products when it comes to air treatment. Knowing what you’re after in terms of compressed air quality, as well as the purpose of the equipment, are crucial in ensuring that you have the right air treatment product for your specific needs. Breathing air purifiers As employers become increasingly aware of their responsibility to comply with International Breathing Air Standards, breathing air purifiers have become standard in some work environments where contaminants such as fumes, oil, vapours, gases, solid particles and micro-organisms are present. Our wide variety of air purification products range from simple respirators that offer basic protection against low levels of dust particles to self-contained breathing apparatus for highly contaminated environments. Compressed air dryers Compressed air purification equipment must deliver uncompromising performance and reliability, while also providing the right balance of air quality and low operation costs.

Compressed air is widely used in everyday life, both in the home (e.g. aerosol cans) and for industrial purposes (food processing, electronics, health care, photography, dairy and instrumentation), so much so that consumers often don’t think twice about it. When people sit down to a meal, for instance, the last thing they think about is the quality of the compressed air that was used in the preparation and manufacture of their food. Little do they know that many food manufacturing companies would not be able to function or provide consumers with safe, contaminant-free products without the use of clean compressed air. From an industrial standpoint, compressed air is often the energy source that powers up pneumatically operated equipment and tools, including those that mix up granular products, aerate liquids and even render meat products. In addition, they are widely used to convey materials and protect equipment or personnel. It is important to note that not all compressed air is the same. The quality of compressed air is actually subject to quality standards, commonly referenced as ISO 8573-1:2010, and determined by measuring three contaminants: Oil content Water vapour Solid particles According to this measure of quality, there are six different classes or levels of compressed air quality, depending on contaminant level and type. Contamination levels are obviously influenced by the type of air compressor that is used, along with the related compressed air filtration and compressed air dryer units. Typically, however, compressed air quality is divided into four groups based on usage, which are as follows: 1. Breathing air The most common applications for breathing air are found in hospitals or medical facilities, as well as for underwater activities. If you have ever been scuba diving, then you definitely understand the importance of having air that is safe to breathe, free of contaminants and that contains a certain amount of water vapour. On the ISO 8573.1 scale, this comes in at class 1 for contaminants or particles (i.e. there should be none of these present) but in classes 4 to 6 for water vapour. 2. Process air When manufacturing a product that will be consumed by humans or animals, process air is often used in the production process. Not surprisingly, compressed air that meets the standard needs to have zero oil or particle contamination, so food manufacturing companies or even drug companies require their compressed air quality to meet ISO 8573.1 class 1 or 2. 3. Power air Usually used in pneumatic pumps or equipment such as those used for sand blasting, for instance, the quality of compressed air used for these purposes tend to be a little lower than the first two types of compressed air mentioned above. For power air, oil droplets or water vapour might cause a bit of a nuisance, but it certainly isn’t life threatening. In order to not damage equipment and clog up filters, power air needs to meet class 4 or 5 of the compressed air quality standard. 4. Instrument air Used for pneumatic instrumentation purposes, the compressed air quality for instrument air needs to be higher than that of power air, and generally meets class 3 or 4 of the compressed air quality standard. This is not only to protect the equipment and instruments that it is being used for, but also to protect the quality of the finished product. Instrument air with a high level of contaminants could affect the quality of the product that it is being used on, such as in paint spraying, for example, or cause untimely instrumentation breakdowns, leading to lost revenue.FIND OUT MORE
As those who work in industries that require the use of compressed air know, it is very important not to get excessive water trapped in the air, whether in the vapour or liquid phase. Compressed air contains not just water droplets and vapour but also debris, oil, and other foreign matter. If there is too much water vapour in the compressed air, this could cause a number of operational problems that range from corrosion and rust in pipelines to fouling of processes and frozen external airlines. Compressed air dryers are mechanisms that remove water vapour from compressed air. There are three common types of compressed air dryers: refrigerated compressed air dryers, membrane compressed air dryers and desiccant compressed air dryers. Refrigerated Compressed Air Dryers These dryers operate via the use of air-to-air and air-to-refrigerator heat exchanges. Incoming compressed air is cooled by the air-to-air exchange, as the outgoing cool and dry air reduce the temperature of the warmer incoming air. This incoming air then goes into the air-to-refrigerator exchanger, where the temperature is reduced through the use of liquid refrigerant to 3 degrees Celsius. This condenses any moisture that is present in liquid water, which subsequently drains off, and the cool outgoing air starts off the process all over again. Membrane Compressed Air Dryers Membrane dryers remove both contaminants and water vapour, as they are a filtration system that works with existing compressed air systems. Humid compressed air passes through a bundle of hollow fibres made of a membrane designed specifically to attract water vapour. Moisture is diffused through to the outside of the thin membrane where it is removed, and the higher the pressure in the compressed air system, then the better the membrane dryer will perform. This is a space saving system and does not use refrigerating agents in its operation. Desiccant Compressed Air Dryers As the name suggests, this type of compressed air dryer works by moving compressed air through a compartment that is filled with desiccants. Desiccants are materials with natural moisture absorbing properties. A desiccant compressed air dryer or regenerative dryer as it is also known usually has two identical desiccant chambers. The unit will automatically use one compartment to dry out compressed air while the other compartment, which is also filled with desiccant, is being regenerated. The use of the two compartments alternate automatically, ensuring a constant supply of dry compressed air, and because it self-regenerates, it also allows for easy maintenance of the unit. The regeneration can be done utilizing heat, compressed air, vacuum or a combination of these technologies.FIND OUT MORE
When it comes to the types of air compressors that are available on the market, there are as many kinds as there are uses for an air compressor. The choice of which air compressor is right for you largely depends on the industry that it is being used in, whether it’s a compact, relatively silent scroll air compressor for the workshop you’re after, or the centrifugal, which is used in large industrial facilities, petrochemical and utilities. Here at Cleveland Compressed Air Services, our wide selection of quality air compressors include: Oil Lubricated Compressors Boge Screw Compressors SolidAir Screw Compressors Boge Piston Compressors Oil Free Compressors Boge Piston Compressors Boge Screw Compressors Cameron Turbo Compressors LENTO Water Injected Screw Compressors High Pressure Compressors Cameron High Pressure Compressors Boge Piston Compressors Piston (also called reciprocating) compressors and screw compressors are the most commonly used types today, and these come in oil lubricated and oil free models. The benefits of oil lubricated compressors include durability, capability to work in extreme environments, longer life spans and better protection against interior rust; however, they do have what is known as “oil carryover”, where a portion of the lubricant comes out with the compressed air. Also, oil lubricated models require re-oiling, oil changes and are heavier. For industries where the air that comes out needs to be completely oil free, oil free compressors are used. These compressors are more expensive to procure and do require more energy to produce the same amount of air; however, the lower maintenance of filtration and no oil change requirement do offset some of the costs. The oil free screw compressors also have a limited life and drop in efficiency overtime owing to the Teflon coating required on the rotors for self-lubrication. Water injected screw compressors do not suffer from the same problem, as water is a very good replacement for lubricating oil. Oil free compressors are also noisier but water lubricated machines have a lower noise output due to the dampening effect of water. Piston compressors, which start up quickly and can be left idle for long periods of time, are usually used in smaller factories and workshops with some use in specialised high pressure applications. Small piston compressors are easy to maintain and cheaper than many of their counterparts, the bigger range being very expensive to maintain and operate. Screw compressors, on the other hand, are used in situations where there is a larger air demand. They are known for their durability, consistently high output and acceptable operating volume level. Although they are generally more expensive than piston compressors, screw compressors do use less energy, are more reliable and, if properly maintained, can be left to run constantly. Centrifugal compressors are dynamic in nature and, therefore, are continuous flow units that are able to cater for large flow rate requirements in oil free and plant air applications. The centrifugal technology was originally limited to low pressure applications but these days medium to high pressure ranges are also catered for. The advantages of going with centrifugal compressors include oil free air production, low specific energy requirement, low maintenance and high reliability. The versatility of air compressors, and the high quality of our compressors in particular, make them especially reliable pieces of equipment that can be used in a variety of industries. These include: Heavy industry Medical Mining Oil and gas Workshop Food and Beverage Of course, these are only some of the uses of air compressors, which have gone from being staple pieces of equipment in power stations, oil and gas rigs, and manufacturing plants to home workshops and garages.FIND OUT MORE
