How GreenFumeHood 3® works
Air is drawn and filtered
Contaminated air passes through advanced filters that trap chemicals using high-retention molecular filtration.
Multi-layer safety
A main filter and backup safety filter ensure no pollutants are released, even when filters become saturated.
Smart monitoring
Built-in sensors continuously check airflow, filtration performance, and safety conditions in real time.
Clean air recirculation
Purified air is safely returned to the room with zero emissions.

When premium protection matters
GreenFumeHood 3® is more than an alternative to traditional ducted fume hoods—it’s a premium solution built for laboratories that need greater control, flexibility, and long-term performance. By combining high-efficiency filtration with intelligent monitoring, it delivers the same level of containment as ducted systems while removing many of their limitations
Unlike conventional hoods that depend on complex ventilation infrastructure, GFH 3 operates as a self-contained system. It captures and filters chemical pollutants at the source, then safely recirculates clean air back into the room. This approach not only maintains a high level of safety, but also significantly reduces energy consumption, infrastructure costs, and environmental impact
GFH 3
Tailored to your Chemical Risk
GreenFumeHood 3® isn’t a one-size-fits-all solution—it’s recommended based on a precise chemical risk assessment carried out by our experts. By analyzing the substances you handle, we define the optimal filtration configuration to ensure the highest level of protection from day one .
And because your laboratory evolves, GFH 3 evolves with you. Its modular filtration column can be quickly reconfigured to match new applications—whether you’re introducing different chemicals, processes, or workflows. No heavy modifications, no operational disruption—just continuous, reliable protection adapted to your needs
Got questions about GFH 3?
Can GFH 3 handle multiple types of chemicals at the same time?
Yes. GFH 3 is designed to handle a wide range of substances simultaneously, including solvents, acids, and bases, thanks to its advanced molecular filtration technology. This makes it suitable for diverse and evolving laboratory applications.
What happens in case of a malfunction or unsafe condition?
GFH 3 includes a smart alert system that immediately notifies users through visual and audible signals if airflow, filtration, or safety conditions fall outside acceptable ranges, allowing quick action to maintain protection.
Is GFH 3 difficult to install in an existing laboratory?
Not at all. As a ductless system, GFH 3 requires no connection to building ventilation. It can be installed quickly with minimal disruption, making it ideal for both new labs and retrofits.
How is filtration performance verified over time?
GFH 3 continuously verifies filtration efficiency using dedicated chemical sensors that detect specific compounds such as VOCs, acids, or formaldehyde. This real-time monitoring ensures that the filters are performing as expected and provides immediate alerts if performance begins to decline, maintaining a constant level of safety.
