Fume hood is one of the important safety equipment in laboratory , it is an effectient partial ventilation . Proper selection ,installation ,operation and maintenance ,the fume hood can keep users away from chemical reagents and other harmful substances.at the same time ,if a fire or explosion occurs,the fume hood will provid adequate security .

BOKA provide fume cupboards in standard width of 1200,1500,1800mm . however we also design custom-tailored solutions . our designed fume hood have benchtop fume hood ,low-height fume hood,low level fume hood and walk in fume hood .Worktop and interior lining are configured commensurate with the associated details ,gases and liquids used ,vapours and aerosols.

Standard fume hood

Technical data

Multi-function fume hood

Features

1. The fume hood monitor LCD display screen,real0time display of the face velocity speed and control valve state ,to remind the user the fume hood’s usage state .

2. Fume hood exhaust air valve adjustable ,also maintain the face velocity speed of 0.5±15% .under the condition that the specificed exhaust volume and average face velocity speed are maintained at 0.5m/s , the resistance of the fume hood is less than 70 pascals .the change of the average face velocity speed only occurs when the sash is moving .once the sash is moved to a certain position . the average face velocity speed will restored to 0.5m/s ,and the response speed is less than 1.5s .

3. When the fume hood is closed ,the air volume valve shall maintain the minimum exhaust volume of the fume hood to meet the actual requirements .

4. If the face velocity speed of the fume hood is less than 0.25m/s ,an orange LED flash will appear,indicating the user’s attention .at the same time ,it can set the alarm value of the face velocity speed too low,such as 0.2m/s . and when the face velocity speed is lower than the set value ,the sound and light alarm will be generated .

5. When the user come close to the sash ,the sash will go up automatically ,when go away ,it will go down automatically

6. When put the finger or barrier under the sash ,it will stop
