-
External hood has weak suction power (insufficient airflow control)
-
Dust source is far away, and the external hood is not capturing all the generated dust.
-
It is difficult to move the hood closer to the dust source because it affects work.
-
Added flange to the hood opening.
-
Improved hood controls required airflow and improved suction capacity
◆Solution point
-
Check the hood's suction airflow
-
Check the airflow speed at the dust source
◆Benefits
-
Required airflow can be efficiently reduced
-
Easy to modify
