The direction of air flow is an important factor in every controlled environment. With the help of a visual smoke test we can prove that the ventilation and filtration systems are capable of protecting the critical area from contamination with particles from the environment and to determine whether the direction of movement of the one-way/ laminar air flow is homogeneous under the entire filter / distribution surface.
It is the simplest and most effective method of detecting unwanted dead zones, air pockets, and displaying air paths from inlet to outlet of the room or device. It is also used to visualize the direction of movement of the air between different pressure zones in clean areas using turbulent flow. The visual smoke test is performed in accordance with the recommendations of ISO 14644-3.
For the performance we use a special flowmarker or a smoke tube.
By agreement with the customer, we attach photographs to the report or create a video clip.
