Spoiler alert: That’s outdated thinking. Today’s compact VSD compressors are ideal for small workshops, offering lower noise, energy efficiency and reduced maintenance, even for low to medium air demand.
Fact: VSDs are now available in compact, workshop-friendly sizes
In the past, VSD compressors were too large and powerful for small-scale use, making them a poor fit for workshops. That’s no longer the case. Modern models like the Atlas Copco G 2–7 VSD series are specifically designed for lower airflow applications – without oversizing or unnecessary complexity.
These VSDs offer energy efficiency and precision control with a footprint and sound output suitable for tight workshop environments. That means users no longer need to sacrifice efficiency for space or simplicity.
Fact: VSDs reduce noise, maintenance, and downtime
Small workshops often struggle with space and noise constraints. Piston compressors are loud and typically need cooldown periods. By contrast, Atlas Copco’s compact rotary screw VSD operate as quietly as a household appliance and require less maintenance due to gradual startups and reduced mechanical stress.
Advanced models like the G 2–7 VSD series include features like the Elektronikon™ Nano controller, which offers leakage detection, smart algorithms, and remote monitoring of pressure, temperature, and running hours.
The compact G 2–7 VSD is much less disruptive than fixed-speed compressors, which create distracting noise and airflow changes. VSD models run smoothly and quietly, making the workshop environment calmer and more pleasant.
Fiction: Efficiency doesn’t matter in low-demand applications
Even in small workshops, energy efficiency matters. With piston and fixed-speed compressors, the motor runs continuously at one speed regardless of demand. This often leads to unnecessary energy use and uneven operating temperatures.
Compact VSD avoid these problems by adjusting motor speed to match actual demand, eliminating oversupply and maintaining optimal system temperature.
While VSD compressors carry a higher purchase price than piston or fixed-speed machines, the savings on electricity – which makes up to 80% of a compressor’s lifetime operating cost – quickly add up.
Compared to a fixed-speed equivalent, the Atlas Copco G 2-7 VSD can reduce energy consumption by up to 20%. For users replacing piston units, the difference is even greater, with added benefits like continuous operation and fewer production interruptions.
Fact check summary
Claim: VSD compressors aren’t suitable for small workshops
Verdict: False. Compact VSD compressors are now specifically designed for low and medium air demand applications — offering superior energy efficiency, quieter operation, and lower maintenance costs.
