Summary[edit]
| Description |
English: Figure 10. Conventional (constant-flow) laboratory chemical hood. The constant-flow hood constitutes the oldest, simplest chemical hood design. The exhaust fan introduces a constant volumetric air flow moving through the sash opening. For this hood design, the face velocity is lowest when the sash is wide open; when the sash is lowered the face velocity increases. |
