Particle size distribution
Particle size and distribution determine the pre-separation process, the filter medium and the transport velocity.

AIRPRO EXPERTISE
4 stepscapture, transport, separate and recover without shifting the problem elsewhere
MATERIAL DIAGNOSTICS
Dust is never just dust.
Before discussing fans or filters, AIRPRO analyses the behaviour of the material and its emission patterns. Two workshops producing dust that appears similar to the naked eye may require very different systems.
This initial assessment helps to avoid oversizing the system, selecting an unsuitable filter medium or shifting the problem to the recovery stage.
Dust load
The concentration and its variability determine the filter area, the cleaning process and the discharge system.
Humidity & temperature
Sticky dust or a gas stream close to the dew point can cause deposits and premature clogging.
Abrasiveness
The product, speeds and changes in direction all influence the wear and tear on ducts, bends and separation components.
Risk behaviour
The combustible or reactive nature of the dust must be identified so that appropriate safeguards can be incorporated at the design stage.
Consider the particle size, moisture content and behaviour of the product before selecting the separation technology.
Technological choices
Choose a separation system, not a single unit.
Each technology fulfils a specific role. The right design can combine them to protect the filter, stabilise performance and organise product recovery.
Pre-separation
Cyclone
RELEVANT FOR
Heavy particles, high load
ROLE IN THE PROCESS CHAIN
To relieve the filtration stage and recover a fraction of the product.
POINT TO NOTE
Its effectiveness varies significantly depending on the size and density of the particles.
Continuous filtration
Bag filter
RELEVANT FOR
High flow rates, industrial dust
ROLE IN THE PROCESS CHAIN
Provide a large filter area with organised cleaning.
POINT TO NOTE
The filter medium must remain compatible with the temperature, humidity and chemical composition of the flow.
Filtration in a compact space
Cartridge filter
RELEVANT FOR
Fine dust, space-constrained installation
ROLE IN THE PROCESS CHAIN
Provide a large filter area within a compact footprint.
POINT TO NOTE
Fibrous or sticky dust requires special analysis.
Combine
Integrated cyclone filter
RELEVANT TO
High dust load and requirement for final filtration
ROLE IN THE PROCESS CHAIN
Combining centrifugal pre-separation and filtration within a single process line.
POINT TO NOTE
Airflow balance and continuous extraction are essential for the stability of the system.
AIR HANDLING SYSTEMS
Performance is determined between the source and the hopper.
An excellent filter cannot compensate for poor air intake. AIRPRO designs the system as a technical continuum in which each stage prepares the way for the next.
Capture dust at source without extracting the entire workshop
The hood intercepts the plume at the point where it forms. Its position, its opening and the make-up air determine the actual effective flow rate.
Critical point: capture geometryConvey without creating deposits
The network keeps the particles in motion whilst minimising pressure drops, noise and wear. Each branch must remain balanced.
Critical point: velocity in the ductsSeparation according to the actual dust
Cyclones, bags or cartridges are assembled according to the load and the desired degree of fineness, not according to a predefined catalogue solution.
Critical factor: dust/media interactionRemoving dust without reintroducing it
Airlocks, screw conveyors, big bags or process recovery systems are integrated into the line to maintain airtightness and simplify operation.
Critical point: continuity of extractionInstallation diagnosis
What the duct system reveals.
The symptoms observed in the workshop enable us to identify the appropriate measures and checks to carry out before modifying the installation.
Dust at the workstation
First examine the enclosure, any unwanted openings, the available flow rate and the make-up air.
Deposits in the duct system
Check speeds, horizontal sections, bends, imbalances and shutdown phases.
Filter that becomes clogged
Check for overloading, humidity, unsuitable filter media, insufficient cleaning or faulty exhaust.
Rising energy consumption
Check for leaks, dampers, pressure drops, fouling and operation outside the specified range.
These indicators guide the diagnosis; they do not replace flow and pressure measurements or inspection of the system.

TECHNICAL QUESTIONS
Understand before sizing.
Initial answers to frequently asked questions regarding industrial dust extraction projects.
Can a cyclone replace an industrial filter?
Not always. The cyclone mainly separates the heaviest particles and can reduce the load on the filter. The final level of filtration depends on particle size, concentration and the discharge target.
How do you choose between a bag filter and a cartridge filter?
The choice depends, in particular, on the type of dust, the required filter area, temperature, humidity, available space and the cleaning method. AIRPRO assesses these constraints before selecting the filter media and system design.
Why capture dust as close to the source as possible?
Close-range extraction limits dispersion within the workshop and avoids the need to move an unnecessarily large volume of air. The geometry of the extraction hood is just as important as the extraction flow rate.
What data is required to size a system?
It is necessary to characterise the dust and the process, identify the simultaneous collection points, and ascertain the available layout, operating conditions and the destination of the collected dust. On-site measurements may supplement this data.
Can the separated dust be recovered or reused?
Yes, depending on the nature and cleanliness of the collected product. The discharge system must then be designed in conjunction with the cyclone or filter to prevent air ingress, leaks and unnecessary handling.
When should ATEX risk be taken into account in the design phase?
Where dust may form an explosive atmosphere, its characteristics, ignition sources and the areas concerned must be assessed before determining the dust collection, filtration, cleaning and protective measures.
In which countries does AIRPRO carry out dust extraction projects?
AIRPRO supports industrial projects, particularly in France, Germany, Switzerland and Tunisia. The organisation of surveys, studies and monitoring is tailored to the location and scope of each assignment.
