Air Operated Air Pressure Booster
2NGB Series Single Stage Double Air Drive Gas Boosters
The 2GB Series, offered by Nidhi Automations, provides the same economical pressure boosting as the GB Series, but with a higher flow capacity. Like the GB Series, the 2GB Series is single-stage and is designed to boost inlet gas pressures up to approximately six times the supply pressure (commonly referred to as the 6:1 Compression Ratio).
| Model | Actual Ratio | Displacement Per Cycle -ml | Gas Piston Diameter -mm | Minimum Gas Inlet Pressure (Pi)-Bar | Maximum Gas Outlet Pressure (Po)-Bar | Po Formula (where Pa=air drive pressure) | Gas Inlet | Gas Outlet | Flow (where Pa = 7 Bar) – NL/min |
|---|---|---|---|---|---|---|---|---|---|
| 2NGB150 | 150:1 | 37 | 18 | 60 | 1245 | 150Pa | NPT1/4″ | HF4 | 132 @ Pi=100 |
| 2NGB200 | 200:1 | 24 | 16 | 80 | 1660 | 200Pa | NPT1/4″ | HF4 | 95 @ Pi=100 |
The maximum acceptable air drive pressure (Pa) is 8.3 Bar. Hydrogen gas service add “H2” after the model codes CO2 gas service add “CO2” after the model codes.
