How Often Should You Test Compressed Air Quality?

If your business uses compressed air, the chances are you already know how essential it is to keep it clean. But knowing when and how often to test compressed air quality is when things can get a little confusing, so we’re here to help.

What Are Your Responsibilities?

Whether you’re running a manufacturing plant, food processing facility, or dental clinic, if you’re using compressed air as part of your operations, it’s your responsibility to ensure it meets acceptable safety and quality standards.

Contaminants like oil, water vapour, and particles can actually compromise products, affect equipment, and even pose health risks. That’s why regular cleaning and testing isn’t just something you probably should do – it’s essential.

There are many reasons why compressed air quality testing is important, but it all comes down to taking care of your people, your products, and your reputation.

How Often Should You Test?

There’s no universal ‘one-size-fits-all’ answer, but generally, compressed air should be tested at least once a year. That said, frequency really depends on your industry, and how critical compressed air is to your operations.

If you work in food, beverage, pharmaceutical, or medical sectors, you may need to test more often – every six months or so, or even quarterly. In other industries where air quality is less critical, annual checks are probably enough.

What is the EN 12021 Standard?

The EN 12021is a European standard that sets the acceptable limits for contaminants in breathing air. It outlines what levels of oxygen, carbon dioxide, carbon monoxide, oil, and water vapour are considered safe.

Failing to meet these standards can mean serious compliance issues. Air quality testing helps ensure your system is within those limits, so you have peace of mind knowing your air is safe and your systems are performing how they should.
