PRODUCT TYPE / FUNCTION

The Fisher 299H is a pilot-operated pressure reducing regulator designed to provide controlled outlet pressure over a range of gas distribution, industrial, and commercial applications.

The 299H uses an integral pilot mounted to the actuator casing. In operation, inlet pressure is used as the operating medium and pilot action controls loading pressure on the main diaphragm to regulate downstream pressure.

This specific regulator is marked:

SET PRESS: 10 PSIG
REGULATOR SPG RANGE: 5-16 PSIG
SPG COLOR: RED
REGIST: EXT
MAX IN: 150 PSIG
MAX OUT: 66 PSIG

PRESSURE REGISTRATION

This unit is specifically marked EXT, indicating external pressure registration.

For an externally registered 299H, downstream outlet pressure is transmitted through a downstream control line to the pilot / actuator sensing system.

The 299H manual identifies a 3/4 NPT downstream control line connection for external or dual registration configurations.

This exact regulator is equipped with the RED 5-16 PSIG control spring and is set at 10 PSIG.

MAXIMUM INLET PRESSURE / ORIFICE INFORMATION

The instruction manual specifies maximum operating inlet pressure according to installed orifice size:

1/4 × 3/8 in. – 175 PSIG
3/8 in. – 175 PSIG
1/2 in. – 175 PSIG
3/4 in. – 150 PSIG
7/8 in. – 125 PSIG
1 in. – 100 PSIG
1-3/16 in. – 80 PSIG

This regulator nameplate is specifically stamped MAX IN 150 PSIG.

The visible nameplate does not directly state the installed orifice diameter, so no specific orifice size is claimed in this listing.

BODY / CONNECTION OPTIONS

The 299H Series manual lists body sizes including:

1-1/4 in.
1-1/2 in.
2 in. / DN50

Available construction varies by configuration and includes NPT and flanged versions.

The exact main body connection size and body material are not clearly identified on the visible nameplate photographs, so buyers should verify the physical connections shown in the photos against their existing installation before purchase.

APPLICATIONS

Suitable applications for the 299H Series include gas pressure regulation in:

Natural gas distribution
Industrial gas systems
Commercial gas systems
Pressure reducing stations
Building gas service
Process gas regulation
Gas pressure control assemblies

Compatibility and sizing should be verified using the exact Fisher 299H model code, pressure requirements, flow requirements, gas type, connection size, and system design.
