What are air sampling systems?

Air sampling systems are advanced fire detection solutions that provide the earliest possible warning of smoke or fire. They continuously draw in air through small pipes and analyse it for smoke particles, detecting even the faintest traces before a conventional detector would react. By identifying potential fires at the earliest stage, air sampling systems help protect people, assets, and operations long before smoke or flames become visible.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for air sampling systems.

Early detection for maximum protection

Early detection is crucial in preventing fire-related damage. Air sampling systems give you valuable time to assess and respond before suppression systems activate or evacuation is required. This proactive approach can minimise disruption, protect critical equipment, and prevent the need for costly clean-up after a suppression discharge.

Tailored design and installation

Every air sampling system is designed to suit your specific site and operational needs. Our engineers assess your building layout, environment, and fire risks to create a bespoke solution that provides complete coverage. Each system is installed to the highest industry standards, ensuring reliable performance and long-term protection.

Expert audits and integration

With over 20 years of experience, our team provides professional audits and custom recommendations for your premises. We can also integrate air sampling systems with other fire safety measures such as alarms, suppression systems, emergency lighting, and voice evacuation systems, creating a seamless approach to protection and compliance.

Maintenance and servicing

We offer ongoing servicing and maintenance to ensure your air sampling system remains fully functional and compliant. Regular testing, calibration, and part replacement keep your system at peak performance, supported by engineers who are on hand whenever you need assistance.

Types of air sampling systems

We supply a range of systems to suit different environments and risk levels, including:

  • Very Early Smoke Detection Apparatus (VESDA): ultra-sensitive continuous air monitoring for critical sites such as data centres and cleanrooms.

  • Aspirating Smoke Detection (ASD) systems: laser-based detection for hard-to-reach areas like warehouses or ceiling voids.

  • Ionisation systems: suitable for specific industrial applications.

  • Cloud chamber systems: highly precise systems used in specialist environments such as laboratories or archives.

Your questions answered.

  • It continuously draws air through small pipes and analyses it for smoke particles, providing early detection before a fire fully develops.

  • They are ideal for high-value or sensitive environments such as data centres, cleanrooms, warehouses, and telecommunications facilities.

  • Unlike standard detectors, air sampling systems actively pull air into the detection unit, making them far more sensitive and effective in large or open spaces.

  • Yes. Regular servicing ensures sensors remain accurate, filters stay clean, and airflow levels meet performance requirements.

  • Yes. Air sampling systems can be integrated with alarms, suppression systems, and building management systems for complete protection.
