SITE REQUIREMENTS
Two sources of compressed gas are required to operate the instrument: 1) shop drive air supply to
power the booster; 2) high pressure gas that the booster will compress to higher pressures. Due to
the different flow rate and cleanliness requirements for each of these supplies, they should come
from two separate sources. It is not recommended that hazardous gases be used unless appropriate
precautions are taken.
1) Shop drive air supply:
The shop air drive supply powers the booster. The booster output is approximately 75 times the
drive air supply (GB-K-75) or 152 times the drive air supply (GB-K-152).
Shop drive air requirements are:
Pressure:
- For operation up to 25 MPa (3 500 psi) with GB-K-75: 0.4 MPa (60 psi) minimum
- For operation up to 50 MPa (7 500 psi) with GB-K-75: 0.7 MPa (100 psi) minimum
- For operation up to 50 MPa (7 500 psi) with GB-K-152: 0.4 MPa (60 psi) minimum
- For operation up to 76 MPa (11 000 psi) with GB-K-152: 0.5 MPa (75 psi) minimum
Flow rate:
- 425 slm (15 scfm) minimum
Cleanliness: Not critical, use 60 micron filter
Humidity: 20 to 50 % RH. Do not use dry gas. Do not use hazardous gases.
2) High pressure instrument gas supply:
High pressure instrument gas is boosted by the booster and supplied to the PPCK+ SUPPLY
port. It is also regulated down and supplied to the PPCK+ DRIVE IN port.
High pressure instrument gas supply requirements are:
Pressure:
- 2 MPa (300 psig) minimum, 20 MPa (3 000 psig) maximum
Flow rate:
- 140 slm (5 scfm) minimum
Cleanliness: Use clean, dry instrument grade gases only. Filtration of 10 micron and moisture
content of –20
°
C is recommended.
