To ensure proper care, you can choose between in-house maintenance by hiring qualified experts or outsourcing the services to reputable providers. Remember, regular servicing by using genuine OEM parts is essential for maintaining energy efficient air compressors. Neglecting maintenance, however, can lead to increased downtime, higher energy consumption, and expensive breakdowns.
To maximise energy efficiency, it&#;s important to check your air compressor for leaks and immediately address them. Even small leaks can have a significant impact on the overall efficiency of your compressed air system. Therefore regularly check all components, including couplings, hoses, tubes, fittings, pipe joints, quick disconnects, FRLs, valves, and flanges, for potential leaks. By actively addressing leaks and adopting energy-saving practices, you can effectively maintain the efficiency and extend the lifespan of your air compressor system.
Moreover, buying an air compressor from a reputed provider ensures that it is of high quality, durable, and offers high efficiency. Therefore, when you&#;re looking to purchase air compressors for your plant, consider Bimpex, a trusted distributor known for delivering high-quality air compressors in India.
To maximise energy saving measures for air compressors, ensure optimal pressure while running your air compressor. A reduction of just 2 psi cuts costs by 1%. If your compressor is underperforming, check for new leaks or increased consumption. Keep in mind that higher pressure worsens leaks. Consider installing a central supply-side controller to regulate pressure effectively.
Operating at the lowest pressure your system can handle can result in approximately 15% energy savings. For industries not requiring pressures above 100 psig, lowering header pressure saves energy.
Pressure drops in a compressed air system can cause problems over time, making it less efficient. To fix this, it&#;s important to deal with suspected pressure drops quickly. These drops slow things down and waste energy.
You can minimise pressure drop by doing a few things such as redesign the system layout, replace broken hoses and tubes, check pipe connections, clean or change filters, adjust regulators, swap out lubricators, and replace after-coolers if needed. Taking these steps will make your air compressor work better and save energy in the process.
When it comes to optimising energy usage, it&#;s important to consider turning off the air compressor during periods of downtime. By identifying specific times when the compressor isn&#;t needed, such as overnight, or during scheduled maintenance breaks, you can effectively reduce energy consumption. Before shutting it down, close supply valves, release system pressure, and power it down safely following the manufacturer&#;s guidelines.
It&#;s important to monitor pressure levels during downtime to avoid disruptions to equipment or processes. If your compressed air system has a storage receiver, you can use it to maintain a sufficient supply of compressed air without the need for continuous operation. Also, pay attention to air quality during downtime, especially if you have filtration or drying.
A supply side controller is a device that optimises the compressed air system performance by monitoring and controlling components such as compressor, dryer and filters. This ensures that the compressed air system operates at the most energy-efficient levels by adjusting the compressor output based on the actual demand for compressed air.
It results in energy savings, reduced wear and tear on the equipment, and lowering power consumption in air compressors. Additionally, a supply side controller can help identify and address inefficiencies in the system, further improving overall cost-effectiveness.
Upgrading your compressed air piping improves the flow, system efficiency, and saves money. Modern piping with better flow characteristics and proper sizing reduces pressure drops, ensuring efficient and smooth air delivery. It also addresses air leaks, reducing energy waste and extending the lifespan of the air compressor.
Additionally, using corrosion-resistant materials improves air quality, preventing contamination and maintaining a clean flow. This results in improved system performance, lower operational costs, and increased overall productivity.
To optimise your air compressor system, consider increasing wet storage capacity to ensure your dryer operates at its designated flow rates. Implement dry storage and a demand controller to handle peak events, while point of use storage maintains lower header pressures for intermittent loads. While a smaller differential means less useful storage, air receivers can help maximise its efficiency.
Additionally, explore the option of compressed air energy storage for storing energy using high-strength air-storage tanks, particularly for smaller-scale applications like air cars and air-driven locomotives.
9. Regular maintenance of equipment like aftercooler or dryer
To ensure optimal functioning and cost savings in your air compressors, it is crucial to prioritise regular maintenance for equipment like aftercoolers and dryers. Aftercoolers play a vital role in cooling compressed air and removing moisture. It is important to maintain the aftercoolers so that they discharge air at a temperature approximately 20°F above the ambient temperature. This lower temperature reduces the moisture load on the dryer, resulting in improved efficiency.
Moreover, regular cleaning and maintenance of aftercoolers and dryers are essential to control the dew point, prevent corrosion, and minimise system contamination. By dedicating time and effort to regular maintenance practices, you can enhance energy efficiency, extend the lifespan of your equipment, and reduce overall operating expenses.
To ensure optimal performance and cost savings with your air compressor, it&#;s crucial to regularly check and change the filters. Air compressor filters are responsible for removing contaminants like dust and debris from the compressed air, preventing damage and maintaining air quality. Over time, filters can become clogged, reducing airflow and efficiency.
By routinely inspecting and replacing filters according to the manufacturer&#;s guidelines, you can maintain proper airflow, prevent strain on the equipment, improve energy efficiency, and avoid costly repairs. Also, after each use, turn off the air compressor, let it cool, and wipe it down for proper maintenance.
Using the correct air compressor is essential to ensure efficient operations in various industries. Choosing a compressor that has VSD helps in saving power. For example, automotive air compressors such as reciprocating air compressors and screw air compressors are ideal for the automotive sector, where they provide reliable compressed air for various applications.
Reciprocating air compressors are also used by industries such as medical, food and beverage, textile, and pharmaceuticals, where oil-free and clean air is crucial to meet strict quality and hygiene standards. By selecting the appropriate compressor type for each industry, businesses can ensure efficient operations, meet specific requirements, and maintain product integrity.

How to Pick the Perfect Scroll Air Compressor
Although the idea for a scroll compressor has been around for over 100 years, the technology is only about 50 years old. As the industry continues to advance, so does the need for reliable, clean, and oil-free compressed air. Scroll compressors are ideal in commercial applications that include: medical, pharmaceutical, food, laboratory, textile, electronics, and production facilities.
Anywhere quiet, clean air is required, a heavy-duty scroll compressor is the only way to go. They come in a wide variety of sizes, up to 40 HP, and can produce as much as 116 CFM! Scroll compressors utilize a very innovative (spiral) design that compresses air quietly with fewer moving parts and less required maintenance.
Scroll air compressors use two spiral-shaped scroll pieces to compress air. One scroll is stationary, meaning it's fixed in place and doesn't move, and the other fits inside the stationary scroll and is moved in a tight circular motion without rotating. The moving scroll presses against the inside of the stationary scroll in such a way that, as it moves in a circular motion, it pushes and traps air into small pockets between the two.

The pockets of air continue being moved through the spiral toward the center. As the air moves further toward the center of the spirals, the air pockets become smaller, and the air in those pockets gets compressed.
Once the compressed air pockets reach the center, they're released into a discharge pipe to be used, or they're released into an air treatment system. An air treatment system is not included with the scroll compressor, as it's typically custom-created with the necessary components to serve the user's desired purpose.
The air treatment system utilizes air delivery piping to deliver the compressed air from the compressor, through a series of filters and dryers, into a receiver tank where the air can be held until it's used. However, some applications that make constant use of the compressed air to run assembly-line machinery may not require a tank.
A major key benefit of scroll compressors is that they're 100% oil-free. For tasks or work environments that require 100% oil-free compressed air, scroll compressors can offer that. The two spirals found in scroll compressors that compress the air don't touch, meaning there's no need to use any oil for lubrication. But this doesn't just mean oil-free air, it also means there are no oil changes.
That leads to the next major benefit of scroll compressors&#;they're very low maintenance. Because there's no oil to change, and there are no spark plugs to worry about, the only real maintenance these machines require is a filter change. This not only saves you time, but it also saves you money. You don't have to worry about changing out oil filters, and you won't experience the costly pressure drop across oil filters.
And speaking of saving money, scroll air compressors are incredibly energy efficient. In addition to the innovative scroll technology and lack of oil filters previously mentioned, these machines are also available with an optional built-in dryer that significantly reduces downstream pressure drop.
And if you're using your scroll air compressor for heavy-duty applications, there's an optional air-cooled IP55 class F motor designed specifically for the tough jobs. Furthermore, they're typically designed for easy serviceability, saving your more time and labor costs. So even if you weren't in need of an oil-free air compressor, the efficiency alone may be worth opting for a scroll compressor.
Last, but not least, it's important to point out that these machines are extremely quiet during operation. The fact that there's no friction between the parts reduces noise significantly, as does the fact that there are no reciprocating pistons - keeping motion more smooth and balanced to reduce vibration.
When choosing a scroll compressor, first determine which type of electrical service you have, either single or 3-phase power. Single-phase is the standard type of service, while 3-phase power is a special commercial power service. If you have access to 3-phase power, you can benefit greatly from the high-efficiency premium motors that are available in those models.
Next, consider the varying specs. How much pressure do you need? Scroll compressors generally come in 116 PSI or 145 PSI, and both single-phase models and three-phase models come available in either one. Cubic feet per minute (CFM) is another spec you should consider when selecting a scroll compressor.
CFM is the amount of high-pressure air being released per minute. This is how much work your compressor can do per minute given a set PSI. So, a 116 PSI unit that puts out 55.1 CFM will be capable of completing tasks faster than a 116 PSI unit that puts out 8.9 CFM. Don't forget the optional built-in dryer for reducing pressure drop.
If you'll be using your new scroll air compressor for heavy-duty operation, you can also consider the optional air-cooled IP55 class F motor, which is totally enclosed and highly efficient.
