Description
Laboratory Fresh Air System
Generating Scenes
chemical reagent volatilization, laboratory exhaust, disinfectant residue, equipment emissions, etc.
Adsorption targets
heavy metal vapor, radioactive iodine (I-131), VOCs, acidic/alkaline gases, odors and disinfection by-products, microbial metabolites
Application Scenes
chemical Laboratory, biosafety laboratories (BSL-2/3), analytical Test Room, animal room and cell room
Treatment Technology

Clarkson Activated Carbon Series
CKC-LAB-TCLR, CKC-LAB-CHTC
Case
VOCs treatment in a university chemistry lab
Problem: Organic synthesis experiments lead to indoor C7H8 concentration 2.5mg/m³, exceeding the national standard 5 times.
Solution: Installation of honeycomb AC filter + UV photolysis device, air volume 2000m³/h.
Effect: C7H8 concentration reduced to 0.3mg/m³, and the annual carbon consumption reduced by 40%.
Air Purification in Super Clean Room
Semiconductor manufacturing, biopharmaceuticals and other super clean rooms have stringent requirements for air cleanliness, and AMC concentrations need to be controlled at ppb level. The microporous oriented adsorption ability of activated carbon can accurately retain pollutants with molecular weights of 200-500 Da to ensure the stability of the production environment.
Generating Scenes
process emission pollution, pollution introduced by personnel and equipment, external air infiltration, etc.
Adsorption Targets
HF, HCl, H₂SO₄ vapors, amines, VOCs, Ozone and odors, microbial risk
Application Scenes
semiconductor fabs, biopharmaceutical aseptic workshop, aerospace precision assembly room
Treatment Technology
AC adsorption, modified AC, fixed bed adsorption
Combined system: HEPA/ULPA+AC, ion exchange+AC
Clarkson Activated Carbon Series
CKC-SC-TCLR, CKC-SC-CHTC
Case
AMC control in lithography area of a semiconductor fab
Background: Photoresist solvent (PGMEA) led to lens fogging and yield drop 5%.
Solution: added modified AC chemical filters, thickness 30cm , to the circulating air system.
Effect: PGMEA concentration was reduced from 0.5 ppm to 0.02 ppm, and the lens cleaning cycle was extended by 3 times.
