An invisible yet vital shield: industrial ventilation at the heart of safety in high-risk environments
In the industrial sector, certain activities come with considerable risks. Whether in chemical plants, refineries, warehouses storing hazardous materials, or processing workshops, the slightest failure in the ventilation system can lead to serious accidents, explosions, or even human and environmental disasters. At AirGreen, we understand that industrial ventilation is not a luxury but a vital requirement to ensure safety, compliance, and efficiency in these sensitive environments.
Our specialized team in commercial HVAC installation works daily across Montreal, Laval, Longueuil, the North Shore, and the South Shore to design, install, and maintain custom ventilation solutions tailored to the most demanding conditions.
Industrial sectors most exposed to atmospheric risks
Chemical and petrochemical facilities
In these environments, the release of toxic or flammable gases is a constant danger. A high-performance industrial ventilation system is crucial to prevent the buildup of harmful vapors, ensure employee safety, and minimize fire risks.
Welding workshops and metallurgical plants
Welding fumes contain fine particles, nitrogen dioxide, and carbon monoxide. Without effective extraction of contaminated air, workers' health can be severely impacted.
Chemical storage warehouses and laboratories
These spaces require precise control of airflow rates, pressure, and filtration, to prevent cross-contamination and hazardous leaks. At AirGreen, we implement negative or positive pressure ventilation systems, depending on the specific needs of each zone.
Main function of ventilation: dilution and removal of contaminants
A well-designed industrial ventilation system serves several roles:
-
It removes contaminants at the source, using localized extraction hoods or mobile extractor arms.
-
It refreshes ambient air to dilute remaining pollutants and maintain safe concentration levels.
-
It regulates humidity and temperature, which are essential for the stability of certain chemicals.
-
It prevents the stagnation of flammable gases, reducing the risk of explosion.
Our installations in Laval and Montreal include smart systems equipped with gas sensors that automatically adjust extraction rates based on defined safety thresholds.
Testimonial from an AirGreen project in Longueuil: a custom ventilation system for a chemical plant
Recently, our team was commissioned to intervene at a chemical treatment plant in Longueuil, where solvent emissions posed a major risk to staff. The challenge was twofold: adapting a system to a complex configuration, while ensuring 24/7 operation without production interruptions.
Here are the solutions we implemented:
-
Installation of dual-motor extraction boxes, with HEPA and activated carbon filters.
-
Integration of VOC concentration sensors to adjust ventilation speed in real time.
-
Implementation of a heat recovery system to reduce energy losses.
The result: a 94% drop in airborne pollutant concentrations, noticeable improvement in employee comfort, and enhanced compliance with CNESST standards.
Regulations and standards: ventilation is a legal obligation
CNESST, CSA standards, and environmental regulations impose strict requirements regarding indoor air quality in industrial settings. Inspections can be frequent, and penalties harsh in cases of non-compliance.
AirGreen supports its clients from the design phase to ensure that each industrial ventilation system in Montreal or on the South Shore meets regulatory thresholds. Our experts also conduct comprehensive audits to recommend necessary adjustments or upgrades.
Technologies used by AirGreen in high-risk environments
Low-velocity displacement ventilation
Widely used in chemical industries, this technology brings fresh air in from below and evacuates contaminants from above, creating a laminar flow that pushes pollutants away from breathing zones.
Controlled pressure systems
Cleanrooms, laboratories, and ATEX zones require strict pressure control (positive to keep contaminants out, negative to contain hazardous substances). Our installations include variable frequency drives and smart control panels.
Smart sensors and automation
Our industrial ventilation systems in Laval are often equipped with sensors for CO, CO₂, H₂S, and volatile organic compounds. Automated management ensures immediate response if critical thresholds are detected.
Why choose AirGreen for your industrial ventilation projects?
-
Recognized technical expertise in high-risk environments.
-
Custom solutions, tailored to your type of activity, building configuration, and energy goals.
-
Fast response times throughout Greater Montreal: Montreal, Laval, Longueuil, North Shore, and South Shore.

Practical tips: mistakes to avoid when installing industrial ventilation
-
Undersizing the system to save money: this creates immediate risks.
-
Neglecting maintenance: clogged filters or uncalibrated sensors render the system ineffective.
-
Ignoring building layout: poor distribution of air intake and exhaust creates dead zones.
-
Not planning for redundancy: in critical environments, a failure can be catastrophic without backup ventilation.
