ERLAB FILTRATION
The filter that changes laboratory design
Neutrodine® Unisorb technology captures solvents, acids and bases simultaneously. Conventional molecular filters cannot rival this technology, which filters more than 700 chemicals.
GreenFumeHood 3® significantly enhances filtration performance compared with conventional filters. Its advanced technology provides improved pollutant retention, enhanced user protection and extended filter service life.
ERLAB ACTIVE SAFETY
Measured, verified and documented safety
GreenFumeHood 3® integrates embedded electronic intelligence designed to continuously monitor the key parameters required for proper equipment operation. Thanks to a complete monitoring, sensor and communication system, safety is no longer simply assumed: it is measured, controlled and documented in real time.
Embedded electronic intelligence: The GFH3® monitoring system continuously controls filtration status, ventilation operation and critical safety parameters. This permanent monitoring ensures equipment performance is maintained and helps provide optimal user protection.
Safety sensors: GFH3® is equipped with a comprehensive set of sensors that continuously monitor system performance. The face velocity sensor ensures proper airflow, while the pollution sensor detects filter saturation. Temperature and humidity sensors continuously monitor ambient operating conditions.
Communication interface: The communication interface centralizes all safety and operating information. Users have immediate access to critical parameters, preventive alerts and system status. The recorded data also ensures performance traceability through LP Report.
AUTONOMY AND FLEXIBILITY
Free yourself from building constraints
Thanks to its standalone ductless architecture, GreenFumeHood 3® frees you from the constraints imposed by traditional ventilation networks. Simplified installation, rapid deployment and increased mobility give the laboratory greater flexibility while maintaining a high level of safety.
Standalone Plug & Play architecture: GFH3® operates without connection to the building’s extraction networks. This standalone design significantly simplifies installation projects, limits infrastructure work and enables rapid commissioning of the equipment.
Layout flexibility: Without relying on ventilation networks, laboratories can easily adapt their workspaces as their needs evolve. Equipment can be reloacted or integrated into new projects without major technical constraints.
Mobility and ergonomics: The GFH3® architecture promotes equipment mobility while improving users’ daily comfort. Optimized access to controls, high-performance lighting and workstation ergonomics contribute to a simpler, more efficient user experience.

ENERGY EFFICIENCY
Reduce the energy impact of your laboratory
GreenFumeHood 3® operates without exhaust to the outside: air is filtered, purified and recirculated into the laboratory. This approach eliminates pollutant emissions into the atmosphere while reducing energy consumption related to air renewal, heating and air conditioning.
Zero pollutant emissions: Thanks to its fully recirculating filtration, GFH3® captures pollutants at the source and prevents their release into the atmosphere. The laboratory benefits from a more environmentally friendly solution without compromising user protection.
Reduced energy costs: By eliminating the continuous extraction of conditioned air, GFH3® limits losses of heated or cooled air. This technology directly helps reduce the building’s HVAC operating costs.
A more sustainable laboratory: Reduced energy consumption and the absence of external emissions make GFH3® part of a more responsible, more efficient laboratory approach, better suited to today’s environmental challenges.
Discover how GreenFumeHood 3® delivers measurable business benefits, from lower operating costs and greater flexibility to improved sustainability and laboratory performance.

FAQ
Frequently asked questions about next-generation GFH® fume hoods.
What is GreenFumeHood 3® technology?
GreenFumeHood 3® is an advanced filtration technology integrating the new generation of Neutrodine® Unisorb filters, embedded electronic intelligence and a complete safety monitoring system. It enables the design of standalone ductless fume hoods while ensuring a high level of user protection.
Which chemicals can be filtered by GFH3®?
Thanks to Neutrodine® Unisorb technology, GreenFumeHood 3® can filter more than 700 different chemicals, including solvents, acids and bases. Each application is validated in advance by the Erlab Safety Program to ensure filtration compatibility.
What differentiates Neutrodine® Unisorb from conventional molecular filters?
Conventional filters are generally specialized for a single family of compounds. Neutrodine® Unisorb technology combines several complementary filtration media, enabling simultaneous capture of solvents, acids and bases in a single filter while improving retention performance.
How does Erlab validate my application?
Each project benefits from an analysis carried out by the Erlab Safety Program. The chemicals used, their quantities, conditions of use and characteristics are assessed to determine the filtration configuration best suited to your application.
How is safety monitored in real time?
GreenFumeHood 3® integrates an intelligent monitoring system that continuously controls critical safety parameters: air face velocity, filter saturation status, pollution sensor, temperature and humidity. Users are immediately informed through visual and audible alerts.
What is the filter service life?
Filter service life depends on many parameters: the nature of the chemicals, quantities used, frequency of use and operating conditions. Thanks to Neutrodine® Unisorb technology, service life can be significantly optimized compared with conventional filtration technologies.
What are the advantages of GFH3® compared with a ducted fume hood?
Unlike a ducted fume hood, GFH3® does not require a complex extraction network. It reduces installation constraints, improves laboratory layout flexibility, limits operating costs and eliminates pollutant emissions to the outside.
What energy benefits can be expected from GFH3®?
By filtering and recirculating air into the laboratory, GFH3® avoids the continuous extraction of conditioned air. This approach reduces heating, air conditioning and air renewal requirements, enabling significant energy savings while limiting the laboratory’s environmental footprint.
Does GreenFumeHood 3® comply with safety standards?
Yes. GreenFumeHood 3® is based on filtration and monitoring technologies designed to meet the requirements of the standards and best practices applicable to laboratories. Filtration and containment performance are validated according to recognized protocols to ensure user protection.
