Airflow Visualization
See Airflow in Real Time.Diagnose Draft Issues with Confidence.
Airflow is invisible—but its impact isn’t. Draft problems, pressure imbalances, and unintended air movement can affect system performance, energy efficiency, and occupant comfort. Smoke testing provides a simple, visual way to understand exactly how air is moving through a space or system.
From HVAC diagnostics and building performance testing to chimney draft analysis and equipment airflow verification, smoke pellets are widely used to trace airflow patterns. By introducing visible smoke into the environment, technicians can quickly identify direction, velocity, turbulence, and problem areas that are otherwise impossible to see.
Diagnosing Airflow Issues with Smoke
Airflow issues are often diagnosed indirectly—through temperature differences, pressure readings, or system performance. Smoke testing removes the guesswork by making airflow visible in real time. Smoke follows the same paths as air, revealing exactly how a system behaves under actual conditions.
Key advantages:
- Provides real-time visual feedback on airflow direction
- Highlights draft issues and pressure imbalances
- Reveals turbulence, backflow, and dead zones
- Works in both small-scale and large environments
- Supports fast, informed decision-making on adjustments or repairs
How Does Smoke Testing Work?
Airflow visualization with smoke is straightforward and highly effective. A smoke source—typically a smoke pellet—is introduced into the area or system being evaluated. As the smoke disperses, it follows the natural movement of air, making airflow patterns clearly visible.
Typical process:
- Select a controlled test area whenever possible
- Minimize external variables (wind, open doors, active fans)
- Place the smoke pellet at the point of interest (intake, outlet, or problem area)
- Ignite the pellet and allow smoke to develop
- Observe and track airflow patterns, noting:
- Direction of movement
- Speed and consistency
- Areas of turbulence or stagnation
- Evidence of backdrafting or reverse flow
- Document findings to guide adjustments or repairs
What This Meansfor Your Operations
Understanding airflow is critical across a wide range of industries. Poor airflow can lead to inefficiencies, safety concerns, and performance issues that are difficult to diagnose without visualization. Smoke testing provides a practical tool for identifying and correcting these problems.
Improve HVAC system performance and efficiency
