Variable speed drive (VSD) technology is a system that adjusts the motor speed of a compressor in response to changes in compressed air demand. This allows the compressor to use only the necessary amount of energy, reducing energy consumption and costs. VSD compressors are ideal for applications with fluctuating air demands, where they can provide average energy savings of up to 35% compared to fixed speed compressors. Additionally, a VSD compressor can start and stop under full system pressure without the need to unload, eliminating idling time or blow-off losses during normal operation. This results in quicker and more cost-efficient start-up with lower system pressure. Furthermore, VSD compressors can provide an average reduction of up to 25% in the compressor’s total lifecycle cost.

On the other hand, fixed speed screw compressors operate at a constant speed, regardless of the demand for compressed air. This means that they may use more energy than necessary when the demand for compressed air is low. Fixed speed compressors are better suited for applications with consistent air demands, where the compressor can operate at its most efficient point.
ABAC offers a range of VSD compressors designed to deliver cost and energy efficiency, performance, and reliability. The Formula and Genesis VSD compressors feature an innovative direct drive transmission and an energy recovery system that can deliver energy savings of up to 75%. These compressors are also more efficient than belt-driven transmissions, with Free Air Delivery (FAD) improved by 9% on average compared to the previous range.
ABAC’s Spinn 2.2-7.5 VSD compressors are the ultimate solution for reliable and long-lasting performance. Thanks to their innovative Variable Speed Drive technology, they are more dependable than ever before. With the ability to operate at lower speeds, these compressors experience less wear and tear on their components, resulting in a longer lifetime and lower operational costs. Additionally, the Spinn VSD is super silent and can be installed near the point of use without requiring a separate compressor room, saving on floor space, piping, and installation costs.
With advanced connectivity and intuitive controls, these compressors bring intelligence, ease of use, and valuable insights to your operations. By harnessing these features, you can effectively reduce operating costs and boost productivity, all while tailoring the compressor to your specific situation and needs. The MI MEI 30-45 range is powered by an in-house air end design and gearbox, while the MI 55-75 range is equipped with a direct driven unit - permanent magnet motor (iPM), for energy savings of up to 45% (compared to the fixed speed solutions).
Our advanced technology is expertly designed to minimise energy usage and maximise profitability. Elevate your business with the CROSS Compressor’s exceptional performance and sustainability. Its robust design includes easy service access and an optional integrated dryer for condensation-free, quality air.
Choose from the flexible CROSS 500 and CROSS 900 models, available in floor- and tank-mounted versions, perfect for small-scale operations like body shops and workshops.
Until now, only larger industrial compressors came with variable speed drives (VSD), which adjust their motor speed to the compressed air demand. Their outstanding efficiency can lead to a much lower energy consumption.
That is also the case for the larger models of the new G 2-7 VSD series from Atlas Copco. Here, these drives can offer energy savings of more than 20%.

But choosing a small VSD compressor over a fixed-speed unit has many other benefits that go beyond efficiency. Here are seven of them.
Simply put, VSD compressors are just better. They offer you a greater output and a more stable pressure than fixed-speed compressors. In addition, Atlas Copco’s patented screw element permits a 100% duty cycle. This means that, as opposed to the piston compressors often used in workshops, a small variable speed screw compressor does not require cool-down periods. In other words, it can just keep going. That’s a major benefit for you. The compressors of the G 2-7 VSD series eliminate work interruptions. They allow you to continue working when a traditional piston would need a break.
As noted above, the larger models of the range can take full advantage of the VSD technology. They allow you to achieve energy savings of more than 20%. However, thanks to innovative components, the smaller units are also more efficient than many fixed-speed (piston) models. For example, the patented screw element and the high-efficiency IE3 motor of the G 2-7 VSD minimize your energy use and operating costs.
But their efficiency is not the only way in which the compressors of the G 2-7 VSD range save you money. There is a misperception that, because they involve sophisticated technology, these compressors are less durable. But nothing could be further from the truth. In fact, the VSD technology is less taxing on important components like bearings and belts. That means they typically last longer and require less maintenance.
Thanks to the lower speeds of their element and motor-mounted fans, G 2-7 VSD compressors are remarkably quiet. In fact, they are as quiet as a household appliance. As a result, they can meet stringent noise emission regulations and don’t pose a risk to your workers. And, coupled with their compact size, this means you can install them near the point of use. That is extremely beneficial for smaller operations, such as workshops, that have limited space available.
All G 2-7 VSD compressors come with a state-of-the-art Nano controller. These are true marvels of technology that make the operation of the compressor easier while also optimizing their efficiency and reliability. For example, using a smartphone or a tablet, you can start and stop your compressor. You can receive notification and alerts and ensure that you have all necessary information concerning your G at your fingertips. Nano controllers also come with advanced control algorithms and a leakage protection program.
Because you can tailor the G 2-7 VSD to your needs, it offers the right compressed air solution for your operation. For example, if you need very clean air, it can come with an integrated dryer and filter. Or, if you need air storage, just choose the tank-mounted version. Different vessel sizes are available to meet your compressed air specifications.
Expansion is a goal for many small operations, and the compressors of the G 2-7 VSD range can grow with your business. Getting a larger fixed-speed compressor in anticipation of such an expansion means that you will waste a lot of energy in the meantime. But that’s not the case with a small variable speed compressor. And, because the Nano controller can securely receive over-the-air updates, you never miss out on the latest algorithms and other advancements.
For all of these reasons, the small variable speed compressor from Atlas Copco is a true game changer. Best of all, it makes the decision which starter compressor is best for you very easy. The compressors of the new G 2-7 VSD range from Atlas Copco simply are that much better. Whether it comes to efficiency, reliability, quiet operation or ease of use, the G 2-7 VSD is the future-proof choice.
