Isolator Dimensions and Operating Parameters
| Isolator | Volume (ft3/m3) | HEPA-Filtered Positive Pressure (inches of water) | Vertical Air Velocitya (ft/min; m/sec) | Air Changes (per hour) |
|---|---|---|---|---|
| 3-glove transfer | 25/0.71 | 0.20 | 12.99; 0.066 | 30 |
| 8-glove transfer | 40/1.13 | 0.20 | 32.87; 0.167 | 49 |
| 12-glove filling | 180/5.10 | 0.25 | 94.49; 0.480 | 20 |
↵a The 3- and 8-glove transfer isolators operate under turbulent air flow, and vertical air velocity was measured at the filter face.
