Maximum compression ratio
| Blower Type | Maximum Compression Ratio |
|---|---|
| Centrifuge |
Single Stage: 3:1 (130 PSIG) Multistage: 5.5:1 (65 PSIG) |
| Roots |
Single Stage: 2:1 (15 PSIG) Two Stage: 3:1 (130 PSIG) |
| Screw | 3.5:1 (36 PSIG) |
Note: Blower outlet pressure is limited to 30 PSIG at sea level. Low-pressure compressors are capable of producing higher pressures.
