Barfield 2311FA Pressure Tester

The Barfield 2311FA Pressure Tester is designed for field and shop testing of aircraft pressure systems in both piston and turbine engines. It generates pressure to test transmitters, warning switches, pressure-type torque (BMEP) indicators, and system leaks in the range of 0 to 600 PSI. Its durable, portable design makes it ideal for use in hangars and line maintenance operations.

Yes, the 2311FA is specifically engineered for versatility. It is self-contained, requiring no external electrical or pneumatic source, and can be used effectively in both line maintenance and repair shop settings. The manual operation and rugged construction make it ideal for on-site testing where portability and reliability are essential.

The unit generates pressure through a manually operated screw piston connected to a fluid reservoir via a control valve. This allows the operator to precisely control test pressure, making it suitable for calibrating and verifying pressure-sensitive aircraft instruments. The piston system provides smooth, incremental pressure changes for accurate readings.

No, the Barfield 2311FA Aircraft Pressure Tester does not include pressure gauges with the base unit. Depending on their accuracy needs, users can select from two compatible gauge types: standard gauges and inspector test gauges.

Standard gauges feature an accuracy of ±2% of full scale and are available in pressure ranges of 0 to 60, 0 to 200, and 0 to 600 PSI. For more precise calibration and testing, inspector test gauges offer ±0.5% full-scale accuracy and are available in ranges including 0 to 60, 0 to 100, 0 to 160, 0 to 200, 0 to 300, and 0 to 600 PSI.

The Barfield 2311FA uses Viton (fluorocarbon) seals, which are compatible with most aviation fuels, lubricants, and hydraulic fluids. However, the tester must not be used with alcohols, aldehydes, amines, alkyl phosphate esters (such as Skydrol), ethers, or ketones, as these can degrade the seals and damage the equipment.

No. The 2311FA Pressure Tester is completely self-contained and does not require an external electric or pneumatic power source. This design enables use in remote or mobile testing environments, making it a reliable tool for field maintenance crews.

Barfield recommends annual calibration of the 2311FA to maintain measurement accuracy. Regular visual inspections for seal integrity and fluid cleanliness are also advised. Keeping the unit free of debris and using only approved fluids will extend its operational life and maintain reliability.

Constructed from lightweight aluminum alloy, the 2311FA weighs only 2.4 lbs (1.1 kg) and features compact dimensions for easy handling and transport. Despite its light weight, the unit’s rugged build is designed to withstand demanding maintenance environments, ensuring consistent performance during frequent use.

Yes. The tester’s manual screw piston and precision gauge system allow for controlled pressurization and monitoring of leaks in pressure lines, sensors, and fittings. Its high sensitivity and fine adjustment capabilities make it suitable for detecting even minor system leaks.

The 1/8 NPT female outlet port provides a standardized connection point for attaching the tester to aircraft components or pressure systems. This design ensures compatibility with most aviation fittings, allowing easy setup for both calibration and leak testing tasks.

Absolutely! The Barfield 2311FA is compatible with analog and digital gauge configurations, allowing technicians to select the preferred display type based on accuracy needs or testing protocols. This flexibility supports a range of aviation maintenance applications, from general inspections to precision calibrations.

The pressure tester should be stored in a clean, dry environment to prevent contamination or corrosion of internal seals. Before storage, release system pressure, drain residual fluid, and close all valves. For long-term storage, keep the unit covered or in its original case to protect the gauges and fittings from damage.

Yes. The Barfield 2311FA pressure tester includes a Certificate of Calibration and the manufacturer’s Certificate of Conformity (CofC) to support proper documentation for maintenance and quality requirements.
