Concept Smoke Systems at the Cleanroom Technology Conference 2025

Birmingham, UK – 21–22 May 2025 – Concept Smoke Systems exhibited at the Cleanroom Technology Conference UK, held at the National Conference Centre, where industry leaders gathered to discuss the latest trends and technologies in controlled environments . Their exhibition at stand C3 drew particular attention for demonstrations of two innovative systems: the handheld Air Trace MK2 and the VC Aero Micro thermal aerosol generator.

The Role of “Smoke” in Cleanroom Validation

While the term “smoke” often evokes theatrical effects, in cleanroom environments it refers to highly controlled fog used to validate airflow patterns, detect leaks, and test HEPA filter integrity. 

• Airflow visualisation: Devices like the Air Trace MK2 release fine, water-based fog to trace air currents and identify turbulence or stagnant zones

• HEPA filter testing: Thermal aerosol generators like the VC Aero Micro challenge filters with fine aerosols of known size and concentration, ensuring compliance with ISO 14644-3 standards

Spotlight on Concept’s Innovation

Air Trace MK2 – Smart, Portable Airflow Diagnostics

The Air Trace MK2 is a small, active-ingredient generator emitting neutrally buoyant micro-particles tailored for real-time airflow mapping. Ideal for cleanrooms and aseptic processing zones, its portability allows engineers to trace air patterns in situ, detecting leak paths or flow obstructions effectively.

VC Aero Micro – Compact HEPA Filter Integrity Testing

This miniature thermal aerosol generator enables robust HEPA filter testing by producing precise aerosol clouds using substances such as PAO or DEHS. Despite its compact size, the VC Aero Micro boasts class-leading output and is purpose-built to meet stringent cleanroom testing protocols

Cleanrooms underpin high-stakes industries—from pharmaceuticals and biotech to electronics manufacturing—where contamination control is non-negotiable. Effective smoke testing:

• Confirms air change rates and controlled airflow corridors.

• Ensures filter sealing and integrity to prevent molecular or particle infiltration.

• Supports compliance with ISO 14644 and GMP regulations—critical for auditable quality assurance.

With increasing regulatory scrutiny and technological complexity, the ability to quickly and accurately visualise airflow or challenge HEPA filters is now a vital competency.

Concept Smoke Systems reaffirmed their commitment to enhancing contamination control and smart diagnostics across critical industries. Their Air Trace MK2 and VC Aero Micro stand-out as agile, reliable tools for airflow mapping and filter certification.
