Why downsizing is the smarter, cheaper option to turning down the pressure on your air compressor.

Chances are your company’s energy bill is one of its most significant costs, and your air compressor, whilst essential to keeping production going, is also going to be a significant contributor to those energy costs. So how can you lower them?

One option is to turn down the pressure of your air compressor. The other is to simply switch to a smaller compressor. One of them (within reason) may be a viable option. One of them definitely won’t be.


Pressure drop

On the face of it, it sounds reasonable enough. What’s to stop you nipping a few psi off your compressor’s output so that running costs are lower? The problem with this is that the rest of your compressed air equipment – your filters, dryers and separators – are designed for a system operating optimally. Drop the power and your dryer or filters, optimised for a system running at a higher psi, may now be prone to clogging, reducing efficiency, increasing the level of moisture and contaminants in the system, and increasing compressor wear.



Naturally, your air compressor still needs to be able to deliver power to the tools and processes that need it. But sometimes, a business will build in far more capacity than is required. Sometimes, strategic changes will see alternative power sources used for some tools. And sometimes, what starts as the primary power source becomes a secondary one.

When that happens, the air compressor you have may be significantly larger than the air compressor you need.

Downsizing – by buying a smaller new or used air compressor can cut energy costs and free valuable workspace. And it’s always the preferable option to reducing the pressure.
