Adsorption
Desorption
Activation process : from charcoal to activated carbon
• Large internal volume, and large internal surface available for adsorption
• Porous structure
• Produced with different material: wood, coconut shell, dust.
• Trap organic solvents

Solvent recovery
Activated Carbon for Solvent Recovery
The small size pores increase the strength of the bound between the activated carbon and the pollutants.

Handling under progress
“To supplement the lab build out we recommend the use of ductless fume hoods for the remaining required hoods. The combination approach will allow the greatest build flexibility while satisfying safety and cost considerations.”

G‐guard Software
Network managementRemote controlReal Time alerts
The 3 things that makes GFH a reliable and safe solution to your ventilation needs are:
•Filtration fume hood powered by a new generation of Filter able to trap a large range of chemicals
•Sensing technology able to guaranty a pollutant release lower thant 1% of TLVs
•A smart monitoring of a network of GFH with gGuard
FILTRATION DETECTION COMMUNICATION
Why is it important to perform a safety assessment before
designing a lab ?
safety assessment
LP report
Investment
Input information• type of handling• chemical• container• Duration, frequency…
The LP report provides information about:
•Ability of GFH to contain and to trap all the handled chemicals
•Ability to detect the chemicals when one of the filter is saturated
•Filter predictable life time and associated cost of filter replacement
