Tronair 06-4005-3611 Component Pressure Test Unit – 2-Quart Capacity, Skydrol/HyJet Fluids

The Tronair 06-4005-3611 Component Pressure Test Unit is designed to provide a clean, pressurized fluid source for filling reservoirs, bleeding brakes, and testing aircraft hydraulic components. It allows technicians to safely transfer and maintain hydraulic pressure during system servicing. This model supports phosphate ester fluids, making it ideal for aircraft that use Skydrol or similar hydraulic fluids.

The unit can deliver a maximum pressure of 3,000 PSIG (206.8 bar), as indicated in the specifications. This high-pressure capability allows it to handle demanding hydraulic component testing and maintenance procedures safely and effectively.

A certified 5,000 PSI pressure gauge is integrated into the system for precise monitoring of hydraulic pressure. This gauge allows technicians to read pressure accurately during bleeding, filling, or system testing operations, ensuring safe and consistent results.

The test unit ships fully assembled and requires only minimal setup. Before operation, technicians must install the appropriate fluid label, fill the reservoir with clean, compatible hydraulic fluid, and purge air from the system by actuating the manual pump. This process ensures proper fluid circulation and pressure readiness.

Routine maintenance includes replacing the filter element and inspecting the pump seal. The non-bypass filter should be changed at least once a year – or sooner if higher handle force indicates clogging. Additionally, technicians should regularly inspect O-rings and seals to prevent leaks and maintain system pressure integrity.

The integrated hand pump allows for manual hydraulic pressure generation and control. Technicians close the pump release screw, actuate the pump handle to transfer fluid, and use the isolation valve to maintain pressure. Pressure can then be safely released through the shut-off valve when testing is complete.

Operators should always verify fluid compatibility, secure hose connections, and close all valves before pressurizing the system. Overpressurization or use with the wrong fluid type can damage aircraft components. Tronair emphasizes that only trained personnel should operate this equipment to ensure safe, compliant maintenance.

The pressure gauge should be recalibrated according to your facility’s quality system or at regular intervals, typically once a year. Tronair provides a Certificate of Calibration for each gauge and recommends periodic reverification to ensure testing accuracy is maintained.

No. The manual explicitly states that any modification or use of non-OEM parts voids the warranty and releases Tronair from liability. Only Tronair-authorized replacement components should be used to maintain certification, performance, and safety compliance.

Tronair warrants the 06-4005-3611 to be free from manufacturing or material defects for one year from the date of shipment. Replacement parts carry a 90-day warranty. The warranty covers repair or replacement of defective components but excludes wear items and damage caused by unauthorized modification or misuse.

Yes. This component pressure test unit is CE marked, indicating that it meets all applicable European Union health, safety, and environmental protection standards. This certification ensures the unit’s safe and reliable performance in compliance with international regulations, making it suitable for use in both U.S. and global aircraft maintenance operations.
