Smoke Study · Airflow Visualisation
See the air.
Smoke studies that turn invisible airflow into evidence — for safety, compliance, and training.
What a smoke study really shows.
We generate controlled, traceable smoke to visualise how air moves through your environment. The result is a clear, real-time record of airflow patterns, dead zones, pressure differentials, ventilation gaps, and the impact of operator interventions — actionable evidence for QA, validation, engineering, and audit teams.
Studies are conducted at rest, during setup, in operation, and across routine interventions, with documentation retained as compliance-grade evidence aligned to PIC/S, TGA, and ISO 14644 expectations.

What we examine
Six conditions, captured on every study.
Unidirectional airflow
First-air integrity over critical zones, with no ingress from lower-grade areas.
Recovery time
How quickly laminar flow restores after personnel interventions or door openings.
Pressure cascades
Differential pressure between adjacent grades — typically ≥10 Pa where required.
Turbulence & dead zones
Eddy currents and vortex regions that trap, redirect, or stagnate particles.
Transfer pathways
Airflow behaviour during material and personnel transfers between rooms.
At-rest vs in-operation
Static and dynamic conditions, including operator activity per SOP.
Methodology
From plan to report — four deliberate steps.
- 01
Plan
Walk the site, define objectives, identify zones and acceptance criteria.
- 02
Generate
Deploy controlled, traceable smoke with calibrated equipment and safety controls.
- 03
Capture
Multi-angle high-resolution video and stills of airflow behaviour, at rest and in operation.
- 04
Report
Edited footage, annotated stills, written findings, and corrective recommendations.
Our Equipment
Professional-grade smoke generation.
Mr Fogger RAPS
Remote Applicator Probe System
We deploy the Mr Fogger RAPS (Remote Applicator Probe System) — an industry-leading fog generation platform designed specifically for pharmaceutical, cleanroom, and critical-environment smoke studies. Every component is purpose-built for GMP environments.
Controlled output
Digitally regulated fog density for consistent, repeatable results across zones.
Pure water-based
Operates with WFI, DI, or distilled water only — no glycol, no residue, fully GMP-compatible.
Remote applicator probe
Telescoping wand reaches diffusers, HEPA filters, and confined spaces without disturbing airflow.
Wireless operation
Remote-controlled activation keeps operators clear of the test zone during capture.
Portable flight case
Complete system packs into wheeled flight cases — ready to deploy on any site, anywhere in Australia.
Calibrated & traceable
Equipment maintained to documented standards — audit-ready from day one.

What clients say
P Square has delivered more than ten airflow visualisation studies at our facility. Their on-site execution is professional and we've consistently appreciated the turnaround time on the edited footage. The custom HTML dashboard they ship with each study — searchable and organised by zone and date — saves us real time over folder-trawling, and the whole package has been genuinely helpful during audits.
