Knowledge is power: BCAS introduces performance verification programme
31 October 2025
RISING ENERGY costs are putting compressed air system performance under greater scrutiny to deliver faster, higher returns. But, with so many compressor options on the market, how can cost-conscious manufacturers make an informed purchasing decision? Steve Downham, technical officer at the British Compressed Air Society (BCAS) discusses the launch of its new performance verification programme.

We live in a world of comparison. Whether it’s searching for the cheapest insurance deal, finding the best price for that must-have pair of trainers or weighing up the all-inclusive benefits of one hotel trip over another, the internet is our friend!
Empowering businesses' purchasing decisions
For comparing price, perks or performance, as consumers, we are increasingly reliant on digital resources to help us make informed purchasing decisions. But the same can’t always be said for sourcing capital equipment in our working lives.
Buyers rely heavily on manufacturer datasheets to make informed purchasing decisions, but comparing performance data from different brands can be a complex task. And, when it comes to the world of compressed air, this conundrum has left many a purchasing manager scratching their head as they try to assess the differences in power rating, pressure and energy consumption!
That is, until now. BCAS has developed the UK’s first, independent performance verification programme for 50 Hz rotary compressors in the European market.
A UK first
Working with its manufacturer members, the programme produces datasheets which provide a uniform and commercially practical means of comparing performance claims during the specification and buying processes. This ensures that all compressors under consideration are measured using the same standards, allowing buyers to compare true performance across brands.
Independent verification at BCAS’s third-party testing laboratory is the cornerstone of the programme and validates the information published by each manufacturer. Verified data is, by its nature, trustworthy and can be of particular benefit when a company is implementing energy efficiency programmes and needs to report on its carbon reduction efforts with confidence.
Compressed air systems involve multiple variables including kilowatt rating, flow rate, pressure, duty cycle and energy consumption to name a few. Standardised, verified data helps buyers reduce technical complexity and reach a decision faster, without a protracted process of liaising with multiple vendors.
Procurement departments often work within tight budget windows or project timeframes and delays in specifying equipment can postpone larger capital projects or facility upgrades, increasing overall costs.
A long-term investment
In addition, purchasing a compressor should be viewed as a long-term investment. Compressors have an excellent track record for longevity and robust performance; however, mistakes made during specification can increase ownership costs over time.
In many industries, compressed air is a critical utility. If a system fails or underperforms, production can be impacted significantly. Buyers need to act fast to identify and specify a suitable replacement or upgrade to avoid costly downtime. Having the ability to compare different machines quickly and easily, whether assessing different brands or even different models from the same manufacturer, can really pay dividends.
