Green Fume Hoods vs. Ducted Systems
A Practical Decision Guide
Green Fume Hoods vs. Ducted Systems:
A Practical Decision Guide
Are Green Fume Hoods Right for Your Lab?
When designing or renovating a chemistry laboratory, one of the earliest and most critical decisions is choosing between a conventional ducted fume hood and a Green Fume Hood (GFH)—a filtered, ductless system.
This white paper outlines a structured, four-step decision-making process to determine if GFH technology is appropriate. Covering operational and construction cost savings, chemical safety, and equipment compatibility, the guide helps lab designers, facility managers, and engineers evaluate the safety, efficiency, and feasibility of implementing ductless fume hoods for a variety of lab environments.
ERLAB R&D LABORATORY
The engineers and chemists in our state-of-the-art R&D laboratory understand molecular filtration. We are committed to designing products that are safe and of the highest quality, strive to improve our products, and continuously develop new products that provide greater protection in the laboratory.
STRICT SAFETY STANDARDS
We hold ourselves to the highest standard and adhere to the strict AFNOR NF X 15-211: 2009 filtration safety standard as endorsed by ANSI Z9.5-2012.
A PUBLISHED CHEMICAL LISTING
It all begins here. Without this listing, we are not compliant with AFNOR NFX 15-211. Our in-house laboratory tests, as well as independent testing, to verify the retention capacity of over 700 chemicals for our filters.
INDEPENDENT TESTING
Erlab filters have been independently tested multiple times at various concentrations guaranteeing that our safety solutions all adhere to the strict performance criteria of theAFNOR NF X 15-211:2009 standard assuring that the emission concentration at the filter exhaust will always be lower than 1% of the TLV.
APPLICATION QUESTIONNAIRE (VALIQUEST)
Our laboratory specialists will recommend the appropriate filtration fume hood, type of filter, and personalized advice.
CERTIFICATE OF VALIDATION FOR THE CHEMICALS USED IN THE HOOD
A certified PhD chemist issues a Certificate of Validation with a list of the chemicals approved for use in the hood.
Our Safety Program
We back up our products 100%. This program includes your specialized chemical evaluation, validation of your hood upon installation, and a filtration safety specialist at your service to ensure that your hood is operating to its full potential.
