THE UNIT

A complete cell,
not an isolated piece of equipment.

In a medical, pharmaceutical or controlled environment, the laser, enclosure, capture and extractor form a single system to be qualified. The extractor helps control emissions; it does not replace laser safety, close-capture at the part, or zone qualification.

THE THREE PILLARS

Design around
on the actual process.

The choice of source, cell architecture and air management must be qualified together based on the material, production parameters and site requirements.

01
Laser head marking a metal part inside a cell with a capture inlet

Laser interaction

Contrast, depth, surface condition and emissions depend on wavelength, pulse regime, material and the actual parameters used.

02
Enclosed laser cell with protected access, observation window and marking head

Controlled confinement

A closed, interlocked and serviceable cell protects access to the beam while providing a coherent volume for part positioning and capture.

03
Local capture inlet positioned as close as possible to a part being laser-marked

Capture at the source

The nozzle, plenum and ductwork should be designed as close to the plume as possible without obstructing optics, focal plane, visibility or critical zone flows.

INTEGRATION ARCHITECTURE

From the beam
to the exhaust air.

Integration flow is not just “connecting an extractor.” Every interface must be documented: safety, airflow, controls, maintenance, materials and qualification requirements.

Configuration decisions are confirmed with quality management, the HSE team and, when required, the site HVAC operator.

01IK-SERIES

Class 4 laser module integrated into a secured final machine.

02Closed cell

Enclosure, interlocks, part fixturing, axes and signaling adapted to the process.

03Local capture

Intercepting the plume at the laser–material interaction point.

04AD Oracle Pro OS

Filtration, condition monitoring and alert forwarding to the cell.

CHOOSE THE PROCESS

The source is chosen
with the material.

Spectral rangeCommon applicationsPoint of attention in controlled environments
Fibre / Nd:YAG · 1 064 nmMetals and many polymers; annealing, coloring, engraving or ablation.Assess fine metal or polymer particulates, localized heating and surface condition.
Green · 532 nmFine marking of metals, polymers, silicones and sensitive materials.Validate contrast without degrading the substrate or contaminating it with ablation byproducts.
UV · 355 / 266 nmPrecision work, layer removal, polymers, glass or ceramics.Reducing thermal impact does not eliminate fumes, gases or particles.
CO₂ · 10,6 µmPolymers, paper, cardboard, glass, coatings and organic materials.Assess emissions on the actual formulation and the associated thermal risk.

Wavelengths and final choice depend on the material, grade, additives and actual production parameters.

CELL & EXTRACTION

IK-SERIES and
AD Oracle Pro OS.

The IK-SERIES range provides an integrable laser base; the final cell, its protections and automation are the responsibility of the qualified manufacturer or integrator. The AD Oracle Pro OS is a standalone extractor associated with a specific machine or cell, to be distinguished from a centralized installation.

SAFETYClass 4 to be integrated

The final machine must combine an enclosure, interlocks, signaling, maintenance access and a risk analysis.

MONITORINGFilter pressure & lifetime

System status in real time, configurable alerts and escalation strategy to the PLC.

CONNECTIONEmissions to be qualified

The reversible housing and duct circuit are validated according to the HVAC strategy and the site.

CLEANROOM CONFIGURATION

Final filtration
matters too.

ISO 14644-1 classification concerns the concentration of airborne particles. It does not qualify the chemical or microbiological nature of contaminants, nor the overall compliance of the installation.

STANDARD CONFIGURATIONPre-filter → HEPA → activated carbon → exhaust

An architecture combining particulate filtration and chemical treatment according to the documented standard configuration.

CLEANROOM VERSIONPre-filter → activated carbon → final HEPA → exhaust

The final HEPA on the exhaust side retains any carbon fines before they return to the controlled environment and serves as a final particulate barrier in this dedicated configuration.

Effective filtration alone is not sufficient to declare a compliant cleanroom. Layout, airflow, materials, maintenance and the site's environmental qualification remain decisive.

QUALIFICATION & ACCEPTANCE

Tests tied
to the site risk.

Acceptance is built with the customer around a defined worst case: part, material, cycle, emission conditions, safety and environmental requirements.

  1. 01
    Document the installation

    Laser and extractor references, filter configuration, connections, software versions and labeling.

  2. 02
    Test the safety systems

    Interlocks, emergency stop, signaling, extraction fault and restart conditions.

  3. 03
    Qualify the capture

    Observe the plume under representative conditions and verify absence of backflow outside the captured zone.

  4. 04
    Verify product & environment

    Contrast, legibility, surface finish and environmental controls specified by the site protocol.

MAINTENANCE & TRACEABILITY

Performance is
maintained over time.

Filters, ducting and cell-extractor interfaces follow an approved procedure. Their maintenance must prevent re-entrainment of dust, record the operations and trigger a risk review when the material, settings or capture system change.

EQUIPMENT FILEConfiguration, location and filters.
MAINTENANCE LOGOperator, date, filters and disposal.
ALARM LOGEvent, cause, action and return to service.
CHANGE MANAGEMENTReview after any process or material change.

INTEGRATION STUDY

Start from your cell,
not from a theoretical diagram.

Provide the material and its grade, the planned parameters, throughput, layout, zone requirements and exhaust constraints. NWS Laser will help define the appropriate laser, capture and extraction.
