1.1 PRODUCT OVERVIEW
The GB-152-AF gas booster with control kit is intended to provide very high pressure gas supply in a
PGC-10000-AF Pneumatic Gauge Calibration System.
The GB-152-AF includes a pneumatically driven, piston type, self-cycling gas booster. The gas booster
boosts a lower pressure, generally supplied from a bottle (300 psi (20 MPa) minimum), to higher
pressure. The booster is powered by drive air. The high pressure output is approximately equal to the
drive air input times the nominal boosting ratio of 152. In the PGC-10000-AF system, the high pressure
output is connected to the SUPPLY port of a GPC1-10000-AF Gas Pressure Controller.
The GB-152 also includes a drive air control kit and interconnecting tubing. The kit is on a bracket that
can be mounted at a convenient location remote from the booster itself.

2.3 SITE REQUIREMENTS
2.3.1 SITE
There are no special site requirements.
The GB-152-AF gas booster system is divided into two parts: the Gas Booster itself and the
Drive Air Control Kit. The two parts are separated so that they may be installed separately.
The gas booster, which is large and relatively noisy, does not need to be accessed regularly.
It is generally mounted out of the way, for example under and behind a work bench.
The booster may be set horizontally or vertically.
Connections of gas supplies and output need to be considered carefully when selecting the
installation site.
See Sections 2.2 and 2.4 for additional recommendations.
2.3.2 GAS SUPPLIES
Two sources of gas pressure are required to operate the gas booster. They are drive air
(see Section 2.3.2.1) and high pressure instrument gas (see Section 2.3.2.2).
2.3.2.1 DRIVE AIR SUPPLY
The drive air supply provides power to operate the booster. The booster’s very
high pressure output is approximately the drive air pressure multiplied by 152.
This supply is usually “shop” or “factory” air.
Drive air requirements are:
Flow rate: 15 scfm (425 slm) minimum
Cleanliness: Not critical, use 60 micron filter
Humidity: 20 to 50 % RH. Do not use dry gas
Pressure: 75 psi (500 kPa)
Depending on the drive pressure set by the DRIVE ADJUST regulator,
GB-152-AF may generate pressure over 70 MPa (10 000 psi). To limit the maximum
pressure that can be generated by the booster, limit the drive air supply to the Drive
Air Control Kit to 75 psi (500 kPa) (see Section 2.3.2.1).
2.3.2.2 HIGH PRESSURE INSTRUMENT GAS
High pressure instrument gas is boosted by the booster and output from the
booster high pressure OUT port.
High pressure instrument gas supply requirements are:
Flow rate: 5 scfm (140 slm) minimum
Cleanliness: Use clean, dry instrument grade gases only.
Pressure: 400 to 3 000 psi (2 to 20 MPa)
Maximum boosted pressure output is high pressure supply
times 25.

2.4 INSTALLATION AND INITIAL SETUP
2.4.1 GENERAL CONSIDERATIONS
If the GB-151-AF is being installed as part of a PGC-10000-AF Pneumatic Gauge Calibration
System, see Section 2.2.
The GB-152-AF gas booster system is divided into two parts: the gas booster itself and the
Drive Air Control Kit. The two parts are separate so that they may be installed separately.
The gas booster, which is large and relatively noisy, does not need to be accessed regularly.
It is generally mounted out of the way, for example under and behind a work bench.
The booster may be set horizontally or vertically.
The Drive Air Control Kit allows local control of booster operation. The output pressure of the
booster can be set by adjusting the drive air pressure and the SHUTOFF valve turns the
booster ON and OFF. The Drive Air Control Kit is a bracket meant to be mounted at a
location convenient to the operator, for example on the front of a work bench.
When selecting the site for installation of the GB-152-AF gas booster system, carefully
consider access for the connections that need to be made (drive air to the Drive Air Control
Kit, high pressure instrument gas to the booster, very high pressure gas output from the
booster to the GPC1-10000-AF Gas Pressure Controller). Figure 4 presents a typical layout
of a complete PGC-10000-AF system, including the GB-152-AF gas booster system.
The orientation of the booster is of no consequence to its operation. It may be installed vertically,
horizontally or any combination of the two with no affect on performance or maintenance.
A variety of factors must be considered when determining where to locate the gas booster
and the Drive Air Control Kit. Factors include, but are not limited to:
•If control over booster operation (ON/OFF, setting output pressure) by the operator is
desired, locate the Drive Air Control Kit where it can be easily accessed.
•The high gas pressure being generated and associated safety concerns.
•The source of gas supplies (drive air supply and high pressure instrument gas supply).
•Point of use of output pressures.
•Noise levels. The booster operation is noisy.
•Vibration during use.
2.4.2 INSTALLATION
The installation of the gas booster system is broken down into four parts:
•Installation of the gas booster (see Section 2.4.2.1)
•Installation and connection of the Drive Air Control Kit (see Section 2.4.2.2)
•Connection of the booster high pressure instrument gas supply (see Section 2.4.2.3)
•Connection of the booster high pressure output (see Section 2.4.2.4)

2. INSTALLATION
Page 9 © 2007 DH Instruments, a Fluke Company
2.4.2.1 BOOSTER INSTALLATION
To install the gas booster system, follow the steps below:
Place the gas booster in the appropriate location (see Section 2.4.1).
Consider the booster high pressure instrument gas supply and high pressure
output connections. The booster may sit vertically or horizontally.
Orientation does not affect operation.
Use the mounting brackets attached to the booster to secure the booster to a
fixed location if desired.
Due to the reciprocating nature of the booster, it is advised that shock
mounts be used when rigidly mounting the booster.
2.4.2.2 DRIVE AIR CONTROL KIT INSTALLATION
To install the Drive Air Control Kit, follow the steps below:
Identify an appropriate location for the Drive Air Control Kit bracket (see Section
2.4.1). Consider the routing of the tubing to the Control kit from the drive air
supply and from the Control Kit bracket to the booster when selecting a location.
The kit bracket is often mounted on the front bottom surface of a work bench.
Figure 4 shows a typical installation configuration for a complete PGC-10000-AF
system.
Mount the Drive Air Control Kit bracket onto the desired location using the
bracket mounting holes provided.
Back off (rotate counterclockwise) the DRIVE ADJUST regulator and put the
SHUTOFF valve in the OFF position.
Connect the drive air supply to the 1/4 in. NPT F connection on the DRIVE
ADJUST regulator. Use tubing rated for at least 150 psi (1 MPa) working
pressure. See Section 2.3.2.1 for information on drive air supply
requirements.
Maximum input pressure to the DRIVE ADJUST regulator is 150 psi (1 MPa).
Pressures above this level may result in a failure that could damage the instrument
and/or cause personal injury.
Connect the Drive Air Supply Kit SHUTOFF valve output to the booster
DRIVE AIR INPUT port using the 6 ft (2 m) length of 1/4 in. PFA tubing
provided in the GB-152-AF accessories. Both fittings are 1/4 in. swage.

2.4.2.3 BOOSTER HIGH PRESSURE INSTRUMENT GAS SUPPLY
CONNECTION
Connect a high pressure gas supply to the gas booster high pressure IN port.
The IN port is a 1/4 in. NPT F fitting on the high pressure gas filter. Use a thread
sealer to seal the connection. The high pressure gas supply should not exceed
3 000 psi (200 MPa). See Section 2.3.2.2 for additional information on high
pressure gas supply requirements.
Pressure present at the High Pressure IN port will be present at the high
pressure OUT port. Do not supply pressure to the high pressure IN port unless you
are prepared for an equivalent pressure to be supplied to the high pressure OUT port.
2.4.2.4 BOOSTER HIGH PRESSURE OUTPUT CONNECTION
If the GB-152-AF is part of a PGC-10000-AF Pneumatic Gauge Calibration
System, the booster high pressure OUT port is connected to a GPC1-10000-AF
Gas Pressure Controller SUPPLY port (see the GPC1-10000-AF Operation and
Maintenance Manual). The GB-152-AF includes an interconnection kit with
fittings necessary to connect the high pressure OUT port to a GPC1.
To connect the GB-152-AF high pressure OUT port to the GCP1 SUPPLY port,
proceed as follows:
nRemove the orange plastic dummy plug from the DH500 fitting in the GB-152
OUT port. Retain the collar that is on the plug.
Remove the orange plastic dummy plug from the DH500 fitting in the
GPC1-10000-AF SUPPLY port.
Refer to Figure 5. Use the tubing and fittings supplied in the GB-152-AF
interconnections kit (see Table 1):
•Connect the DH500 2.75 in. (70 mm) nipple to the DH500 elbow.
•Connect the DH500 6 in. (152 mm) nipple to the DH500 union.
•Connect the union/6 in. nipple assembly to the open connection on the
elbow/2.75 in nipple assembly.
•Connect the 2.75 in. nipple end of the just completed assembly to the
GPC1 SUPPLY port.
•Connect the 60 in. (1524 mm) x 1/8 in. nipple with DH500 tips to the
open connection on the DH500 union of the assembly that is already
connected to the GPC1.
•Connect the other end of the 60 in. x 1/8 nipple to the high pressure OUT
port of the GB-152-AF.
Test that all fittings tightened before applying pressure.

Depending on the drive pressure set by the DRIVE ADJUST regulator,
GB-152-AF may generate pressure over 70 MPa (10 000 psi). To limit the maximum
pressure that can be generated by the booster, limit the drive air supply to the Drive
Air Control Kit to 75 psi (500 kPa) (see Section 2.3.2.1). Be sure to connect the
booster high pressure output using fittings and tubing rated for the maximum
expected pressure that is to be output from the booster. Always use a DH500 or
equivalent tube on the DH500 F high pressure OUT port connection.

2.5 INITIAL START UP
After installing the gas booster (see Section 2.4.2), perform the initial start up as follows:
Supply drive air: Check that the Drive Air Control Kit SHUTOFF valve is in the OFF position and that
the DRIVE ADJUST regulator is set to zero (fully counterclockwise). Apply drive pressure to the
SHUTOFF valve (see Section 2.3.2.1 for information on drive air supply requirements).
Depending on the drive pressure set by the DRIVE ADJUST regulator, GB-152-AF may generate pressure
over 70 MPa (10 000 psi). To limit the maximum pressure that can be generated by the booster, limit the drive
air supply to the Drive Air Control Kit to 75 psi (500 kPa) (see Section 2.3.2.1).
Supply high pressure instrument gas: Check that all connections to the high pressure IN and OUT
ports are secure. Apply high pressure gas to the high pressure IN port (see Section 2.3.2.2 for
information on high pressure instrument gas).
Ensure the high pressure supply does not exceed 3 000 psi (20 MPa). Pressure above this may result in
a failure that could damage the instrument and/or cause personal injury.
Adjust the DRIVE ADJUST regulator: Rotate the DRIVE ADJUST regulator knob (clockwise)
while observing the set pressure on the DRIVE gauge. Set the drive pressure to the maximum
desired high pressure output divided by the booster ratio (152 for GB-152-AF). Do not set the
regulator to more than 65 psi (450 kPa). Remember that when the SHUTOFF valve is in the ON
position, the booster will operate until the high pressure output is equal to the drive air setting times
the booster ratio.
The DRIVE ADJUST regulator is NOT self venting so it cannot be used to set pressure lower than the
current pressure when the SHUTOFF valve is OFF. If you overshoot the desired set point, set the SHUTOFF
valve to ON until the DRIVE pressure is lower than your desired setting. Then set the SHUTOFF valve to OFF
and use the regulator to adjust the pressure in the ascending direction.
Generate high pressure: Check that the booster high pressure output is properly connected. If it is
connected to a GPC1-10000-AF, be sure the GPC1’s INLET valve is closed. Set the SHUTOFF valve to
the ON position. The booster will begin to cycle and will continue to cycle until it stalls. When it stalls, the
high pressure output is roughly equal to the drive pressure setting times the booster's ratio (152:1).
