Screw air compressors are the more sophisticated counterpart of piston air compressors. The ability of screw air compressors to offer continuous output is unmatched. The operating cycle is one of the biggest differences between piston and screw air compressors.

A piston air compressor provides sporadic output, while screw air compressors work without a break. If you are a business owner looking to source a screw air compressor, this blog is for you. Read until the end to make an informed decision.

Understand Your Air Demand

Since the sole purpose of air compressors is to power pneumatic tools and equipment, considering the following factors is essential.

CFM: Cubic Feet Per Minute is the parameter that decides how much airflow the air compressor provides in a minute. Why is CFM important? The higher the CFM, the more powerful the output is.

PSI: PSI or Pounds Per Square Inch is the pressure at which the air in a compressor is discharged. Understand the pressure level needed for your tools or machinery before sourcing piston air compressors to ensure supply and demand match.

Peak vs Continuous Demand: It is important to understand whether your pneumatic tools and equipment operate non-stop or only during peak hours. Understanding this helps you source screw air compressors of the right size and output capacity.

Why is this important? Sourcing an air compressor that’s too large can lead to excessive energy consumption. Meanwhile, sourcing small air compressors will make it difficult to meet operational demands.

Fixed Speed vs Variable Speed Drive (VSD)

A fixed-speed air compressor works at full capacity for the entire operational cycle. On the other hand, variable speed drive compressors adjust their motor speed based on real-time air compressor demand. Here are applications for which both fixed-speed and variable-speed drive compressors are best suited.

Fixed Speed Compressors

  • Small & medium workshops 
  • Automotive garages 
  • Manufacturing units 
  • Packaging units 
  • Single-shift operations
  • Facilities with limited pneumatic tools
  • Secondary compressors in larger systems
  • Construction sites


Variable Speed Drive (VSD) Air Compressors

  • Large manufacturing plants
  • Multi-shift industrial operations
  • Automated production lines
  • Food and beverage processing units
  • Pharmaceutical and medical manufacturing
  • Precision manufacturing
  • Energy-sensitive operations
  • Businesses planning future expansion


Available Space and Infrastructure

This is one of the most important factors to consider before buying an industrial screw air compressor. Assessing the available space in your facility helps choose the right compressor size and prevents overcrowding. An air compressor demands space not only for installation but also for repairs and servicing. 


Moreover, installing the industrial screw air compressor closely against walls or tight spaces results in poor ventilation. This significantly reduces the performance and lifespan of air compressors.

As far as infrastructure is concerned, ensure power supply compatibility to prevent performance issues or damage. Last but not least, keep the air compressor in an isolated compressor room to prevent operational noise from causing disturbance.

Maintenance and Service

Buying is only half the job. The real challenge lies in ensuring exceptional maintenance and servicing. Talk to the manufacturer or the supplier regarding service intervals, spare part availability, warranty, and the list of post-installation support you will receive. Buying a screw air compressor with a warranty is important for ensuring uninterrupted usage and peace of mind.
