Types of airflow system for an industrial painting installation

Spray booths are installations where it is vital to ensure adequate airflow system. A spray booth allows the optimum conditions for the application and material drying to be achieved by controlling the air flow in and out of the booth, with user control of temperature, humidity and pressure values.

To determine the optimum type of airflow in an installation, different factors are considered.

On the one hand, it is important to ensure compliance with the requirements of the UNE-EN 16985 standard, which meets the safety needs of workers and the environment during the spraying process in booths.

On the other hand, the needs of each client must be decisive in deciding what type of installation to carry out. The possibilities of the working space, the production volume, and the type of product to be painted help us to offer the customer a tailormade solution.

Pressurised spray booths can have different airflows. Depending on the specifications of each industry, the installation could be customized. These are most common airflows:

Spray booths with vertical airflow

In this type of painting cabins the air enters through the ceiling of the booth filtered and flows vertically towards the extraction pit located on the floor -picture 1-. This type of installation requires civil works on site, so it is it is important to know the amount of surface area available at the customer’s site.

It is also possible to assembly a vertical air flow through a spray booth with a raised floor by means of a metal grating and with an access ramp.

Vertical flow is the most common and longest established form of airflow installation, however there are other options to suit customers with different needs

Spray booths with semi-horizontal airflow

In these booths, the filtered air enters through the ceiling, flows vertically, but is extracted or through both sides of the booth, using the side collectors located along the lower part of the booth’s side walls – picture 2 – or thorugh back collectors, located on the back wall of the cabin -picture 3-.

This is a more flexible solution, which adapts to workspaces where civil works cannot be carried out and offers a high level of painting cabin efficiency.

These sidewall collector systems are also used in the preparation areas of painting equipment due to their high extraction and filtering capacity.
