Useful volume
Height, geometry, openings and areas actually occupied determine how air can flow through the building.

AIRPRO EXPERTISE
Fresh airintroduced and controlled to dilute diffuse pollutants and renew the atmosphere
BUILDING SURVEY
Ventilation begins with understanding where the air wants to go.
A workshop is not simply a space in which to circulate air. Machinery, doors, temperature differences and existing extraction systems create air movements that can sometimes work against the desired objective.
AIRPRO draws up this layout plan before determining the airflow rates, in order to treat the occupied area without unnecessarily ventilating the entire building.
Emissions
Heat, steam, fumes or aerosols are identified, quantified and linked to production cycles.
Air flow
Doors, prevailing draughts, existing extraction systems and machinery already create airflow patterns that need to be understood.
Airflow analysis
Extracting without compensating merely shifts the problem.
Effective extraction requires a well-organised air supply. Otherwise, the building will draw in air through its doors, disrupt sensors and create uncontrolled draughts.
Extract
Remove the pollutant or heat at the point of origin.
Compensate
Re-establish a consistent flow rate to prevent uncontrolled negative pressure.
Distribute
Deliver fresh air to the relevant areas without causing draughts that cause discomfort.
Balancing
Adjust the systems to maintain the specified flow rates in the various scenarios.
Exhaust air+Balancing air+Controlled air distribution=Balanced workshop
OCCUPIED AREA
Ventilate people and processes, not cubic metres.
The air distribution system is designed to deliver clean air to where staff are working, and then direct emissions towards their collection or extraction points.
Ventilation strategies
Three phenomena, three different solutions.
A system may combine several strategies. The choice depends on the nature of the emissions and their ability to disperse within the workshop.
Source capture
Capture fumes, vapours or heat before they disperse.
Priority: to enclose the source with just the necessary airflow.Dilution ventilation
Renew the air when emissions are distributed throughout the space.
Priority: to avoid dead zones and control airflow.Air sweeping and stratification
Removing heat by utilising the natural movement of hot air.
Priority: protect the occupied area before treating the entire space.On-site measurements
Make decisions based on data, not on an isolated air change rate.
The measurements link the observed behaviour to the actual conditions within the network. They make it possible to distinguish between a lack of flow and a problem with intake, compensation or distribution.
Airflow rates & velocities
At air outlets, within ductwork and around openings.
Pressures
Understanding building balance and pressure drops.
Temperature & humidity
In the occupied zone, at the sources and in the extracted air.
Production cycles
In order to identify peak loads and simultaneous demand.
Preparing the design study
The information that makes the initial discussion meaningful.
A plan and a few observations are all that is needed to get started. AIRPRO turns these elements into hypotheses to be tested in the field.

TECHNICAL QUESTIONS
Clarify the balance before sizing.
Initial answers to frequently asked questions about ventilation and fresh air supply in industrial environments.
Why is it necessary to replace the air extracted from a workshop?
Without a controlled supply of air, the building will develop a negative pressure, and the extraction system will become less effective. Pressure equalisation also allows the flow of fresh air to be managed without creating annoying draughts.
General ventilation or local exhaust ventilation?
Source extraction remains the priority for localised emissions. General ventilation supplements the system to deal with heat gains and diffuse pollutants that cannot be captured locally.
What data is required for an industrial ventilation study?
Volumes, openings, occupancy, machinery, emissions, existing flow rates and thermal constraints form the initial assessment. On-site measurements are then carried out to confirm the assumptions.
