High-performance filtration technology

Neutrodine Unisorb®, a single molecular filter for all laboratory vapors and gases
The result of the latest innovations from Erlab, GFH® 3 is equipped with a new generation of filters: Neutrodine Unisorb®. This technology has been developed for over 12 years at the Erlab R&D laboratory. It has been tested and deployed since 2009 thousands of times, from the first trials of new filtration materials right up to the performance evaluation of these new filters in real-life situations.
Neutrodine Unisorb® greatly increases the retention capacity for the majority of vapors emitted from a wide variety of laboratory handlings. These improvements are significant for the molecules known to be the most difficult to retain with classic activated carbon filters: polar VOCs with low molar mass and boiling points.

Therefore, filter performance lifespan are improved and operating costs reduced.

A high level of filtration and containment guaranteed by the most rigorous safety standards
Filtration efficiency according to the AFNOR NF X15-211 standard
Neutrodine® filtration technology conforms to the
NFX 15-211 standard, the most rigorous industry standard for molecular filtration, developed by a committee of independent scientists and specialised manufacturers.
This standard establishes the specific performance criteria which impose a maximum release of 1% of the TLV (Threshold Limit Value) of the handled products.
Containment efficiency of the enclosure
The level of containment is defined by the capacity of the fume hood to keep vapors within the enclosure, preventing their release into the laboratory environment. Containment efficiency is proven by tests carried out according to the protocols outlined in the EN14175-3, ASHRAE 110:1995 and
AFNOR NF X 15-211 standards.
The containment standards applicable to GreenFumeHood® Fume Hoods are identical to those for fume extraction hoods.
The XPX15206 standard

Simplify the design of your laboratory and save energy

Compare the infrastructure and operating costs of your fume hood with a fume hood equipped with GreenFumeHood® 3 filtration technology
A study conducted by the University of Berkeley concluded that the annual cost of energy consumption for a fume extraction hood is 4,300 Dollards. A fume Hood operates 24 hours a day... and consumes 3.5 times more energy than an average sized house.*
It is possible to make it more competitive from an ecological standpoint. Erlab’s Neutrodine® Unisorb molecular filtration technology with super-activated carbon primarily protects the user, but also reduces the environmental impact while reducing operating and installation costs.

Did you know?

Energy footprint comparison between traditional ducted fume hoods
and next-generation filtered fume hoods

ducted fume hood
filtered fume hood
The energy cost of a traditional ducted fume hood is estimated at 4,300 Dollars per year. The average annual energy cost for a next-generation filtered fume hood is estimated at 250 Dollars per year.
This average cost has been established for a fleet of 750,000 ducted fume hoods in operation.

The total power consumption of these 750,000 ducted fume hood amounts to the electrical output of 20 x 250-megawatt power plants.
The total cost of this energy consumption is 3 billion Dollars per year.
For the equivalent of 750,000 next-generation filtered fume hoods, this would amount to the electrical output of 0.8 x 250-megawatt power plants.
The total cost of this energy consumption is dramatically reduced to a cost of 190 million Dollars per year.

The electrical consumption of a filtering fume is on average
17 times less than a traditional ducted
and can bring you the following advantages: 
• Reduce energy costs by 96% and reduce operating costs by 70%.

• Reduce infrastructure costs associated with heating and cooling.
• Handle liquids and solids (including acids, bases, solvents and powders)
- individually or together - with a single hood.
• Reduce CO2 emissions.
• Virtually eliminate installation costs.
• Operate safely without polluting and contaminating the environment.
• Maintain productivity without changing the way lab technicians work.
