Evacuation of Air - minimum Capture Velocities to avoid Pollution products transferred to the Room
Capture velocities to avoid pollution products from galvanic baths, spray painting boxes and more contaminating the surrounding room and environment.
The tables below indicates necessary capture velocities of evacuating air in distance x from outlet openings to avoid pollution products transferred to surrounding rooms and environments.
The pollution source is in distance - x - from the outlet opening.
- v1 -
|Galvanic baths, stain baths, kitchen hoods, smith hoods etc.||small||0.2 - 0.5||40 - 100|
|Spray painting, unloading and loading of bags, welding etc.||moderate||0.5 - 1.0||100 - 200|
|Unloading moulds||high||1.0 - 2.0||200 - 400|
|Grinding, honing, sand blaster etc.||very high||3.0 - 10.0||600 - 2000|
|Process Baths||Required Capture Velocity|
- v1 -
|Galvanic, chrome or cadmium||0.4||80|
|Water, not boiling||0.2||40|
