Modern data centres are critical to business operations, powering everything from cloud services to financial transactions. While most operators prioritise cooling, power supply, and cybersecurity, there’s an often-overlooked risk that can quietly cause downtime and costly repairs: airborne particulate contamination (DUST).

What Are Airborne Particulates?

Airborne particulates are microscopic dust, fibres, skin flakes, pollen, smoke residues, and chemical pollutants suspended in the air. In everyday environments, they may seem harmless—but inside a data centre or server room, they can cause serious hardware problems.

Why Airborne Particulates Are Dangerous in Data Centres

If left unchecked, airborne particulate can:

• Cause hardware failures – Dust settles on circuit boards, fans, and filters, leading to overheating and system breakdowns.
• Trigger corrosion – Contaminants such as sulphur compounds corrode sensitive metal components.
• Reduce cooling efficiency – Dust build-up clogs airflow, making cooling systems work harder and driving up energy costs.
• Increase static discharge risk – Dust particles can act as conductors, damaging microelectronics.

Industry Standards for Clean Air in IT Environments

Guidelines such as ISO 14644-1 and ASHRAE standards specify strict particulate levels for data centres. For reliable IT operations, server rooms must remain below ISO Class 8 for airborne particles.

Common Sources of Contamination

Even the most secure server room can accumulate dust and particulate if proper controls aren’t in place. Common sources include:

• Poorly maintained HVAC systems
• Construction or maintenance works nearby
• Staff foot traffic introducing fibres and dirt
• Leaks that allow outside pollutants inside
• Lack of regular server room cleaning

Preventing Airborne Particulate Contamination

Effective data centre cleaning services are essential for maintaining uptime and protecting valuable IT infrastructure. Best practices include:

• Specialist IT cleaning – Regular professional server room cleaning removes particulate from equipment surfaces, floors, ceilings, and raised floors.
• HEPA filtration – Captures airborne contaminants before they settle on hardware.
• Controlled access protocols – Minimise contamination by restricting entry and use Dycem Data Centre Matting/Tiles to remove footborne contamination.
• Air quality monitoring – Routine testing ensures ISO and ASHRAE standards are met.
• Preventative maintenance – Regular HVAC servicing and sealing cable penetrations reduce external contamination.

Why IT Cleaning Matters

For data centre operators, downtime isn’t just inconvenient—it’s costly. Airborne particulate leads to hardware failures, shorter equipment lifespan, and higher cooling expenses. By investing in professional data centre cleaning, businesses can:

• Protect critical IT infrastructure
• Prevent unexpected outages
• Extend hardware lifespan
• Ensure compliance with industry standards
• Reduce overall operating costs
