Eight Benefits of a Small Variable-Speed Compressor

For the first time, the new 2-7kW compressor range brings variable-speed drive (VSD) technology to small users.

Until recently, small workshops with limited space and resources were limited to fixed-speed air compressors for all their compressed air needs. However, thanks to Atlas Copco’s introduction of the G 2-7 VSD, a new and superior option is now available: the small variable-speed compressor.

Before the release of the G 2-7 VSD, variable-speed drives, which can alter their motor speed according to your compressed air demands, VSD options were only found on large industrial compressors. VSD technology maximises the efficiency of your compressor while reducing your energy consumption. VSD technology not only ensures energy-efficient operation but also enhances reliability and reduces wear and tear on critical components.

Now, the G 2-7 VSD brings VSD technology to the smallest screw compressor segment, offering potential energy savings exceeding 20% compared to fixed-speed compressors. This also applies to the larger and more robust models within the new G 2-7 VSD series by Atlas Copco.

The G 2-7 VSD is a game-changer for small workshops, combining compactness with cutting-edge technology to deliver unparalleled performance in this segment​.

Significantly improved energy efficiency may be the primary draw of a VSD compressor over a fixed-speed unit, but the benefits of VDS options extend far beyond electricity savings. This article details eight of the key benefits of a small variable-speed compressor. If you need more information or personalised advice, we are only a phone call away.

Anglian Compressors has been one of the UK’s leading air compression specialists for nearly 50 years, and a premier distributor for Atlas Copco since 1977. Whether you need to repair a few components or want to replace your entire compressor with an energy-efficient VSD alternative, we have got you covered. Call us today or keep reading to learn why new small VSD compressors are taking the industry by storm.

1. Improved Performance

Compared to fixed-speed compressors, VSD compressors offer superior stability in pressure and air output, ensuring a consistent supply of air and minimising downtime in your workshop.

Moreover, Atlas Copco’s patented screw element enables a 100% duty cycle, eliminating the need for ‘cool-down’ periods common in piston compressors. This ensures continuous operation without interruptions .

2. Increased Efficiency: Smarter Power, Lower Costs

Unlike traditional air compressors, which run at full speed regardless of demand, the G 2-7 VSD uses variable speed drive technology to adjust motor speed to match your facility’s compressed air needs. This smart regulation reduces electrical energy consumption by over 20%, significantly lowering operating costs and total cost of ownership.

Equipped with an IE5 ultra-premium efficiency motor and Atlas Copco’s patented rotary screw element, this variable speed compressor maximises air output while minimising power consumption. The smart nano controller further enhances efficiency and reliability by optimising energy use in real time, preventing unnecessary power surges and protecting downstream equipment.

By switching to a small VSD compressor, businesses can save energy, lower costs, and improve air quality – all while maintaining a consistent supply of industrial air for pneumatic tools and various applications.

3. Reduced Maintenance

Many believe advanced features in compressors increase the likelihood of mechanical issues. However, VSD compressors are gentler on critical components, such as bearings and valves, due to their adaptive speed control. This extends the lifespan of parts and reduces overall maintenance requirements.

VSD compressors are much less taxing on critical components such as bearings and control valves, which increases their lifespan while reducing maintenance requirements. And less upkeep translates to significant cost savings in the long run.

4. Straightforward Servicing

Reliable as they are, G 2-7 VSD compressors still require regular maintenance to ensure peak performance. Thankfully, they are designed for easy servicing with panels that provide fast access to key components.

By choosing an Atlas Copco distributor, you ensure that your compressor receives professional servicing, restoring it to optimal condition quickly and efficiently.

5. Quiet Operation

The G 2-7 VSD’s low noise levels not only make it ideal for noise-sensitive environments but also help businesses comply with workplace noise regulations.

Its compact design allows installation close to the point of use, which saves space and minimises pressure loss from long piping.

6. User-Friendly

Equipped with state-of-the-art nano controllers, the G 2-7 VSD compressor is intuitive and straightforward to use – you will not need to waste hours of your time getting accustomed to new equipment. This small variable-speed compressor also comes with a range of advanced features that can help you optimise your work tasks. For example, you can remotely monitor and operate your G 2-7 VSD compressor using a tablet or smartphone. You can also set up custom alerts and notifications.

The ability to control the compressor remotely via smartphone or tablet streamlines operations, allowing businesses to monitor and adjust settings effortlessly​.

7. Flexibility: A Compressor That Adapts to You

The G 2-7 VSD adjusts motor speed to match air demand, making it an energy efficient alternative to fixed speed compressors. This reduces power consumption, energy costs, and total cost of ownership.

It offers an oil-free option with an integrated dryer and filtration system for industries needing high air quality, such as spray painting and pneumatic tools. A tank-mounted version is available for compact air storage.

Its wide pressure range supports various industrial applications. The smart nano controller enables over-the-air updates, ensuring long-term efficiency and reliability.

Businesses can lower costs, improve air quality, and optimise performance by choosing a flexible, future-proof solution.

8. Scalability

Small businesses planning to expand operations can rely on these compressors to meet increasing demand without prematurely investing in larger fixed-speed models.

The nano controller supports over-the-air updates, ensuring compatibility with future technological advancements and enabling businesses to keep pace with industry innovation​.

FAQ

What are the benefits of a variable speed drive (VSD) air compressor?

A variable speed drive air compressor adjusts its motor speed in real time to match the need for compressed air, making it highly energy efficient. Unlike fixed speed compressors, which always run at full capacity, VSD compressors only draw the air needed. This helps reduce energy consumption and operating costs while delivering reliable performance, leading to less maintenance over time.

How does a variable speed rotary screw air compressor improve efficiency?

A variable speed rotary screw air compressor continuously adjusts its operating speed based on the compressed air demand. This ensures the compressor runs only as needed, increasing energy efficiency and reducing wear on key components like the drive train and air inlet valve. By responding to demand in real time, it helps optimise both energy use and compressor performance.

Why is a variable speed air compressor better for businesses with fluctuating air demand?

Variable speed air compressors are ideal for businesses with changing compressed air needs because they can adjust motor speeds to meet maximum demand without wasting energy. As the compressor operates, it accelerates or decelerates based on real-time requirements, ensuring you always use the right amount of air. This flexibility makes them more efficient and cost effective in the long run.
