Need a Quote?
The Interface Devices OB-30 Oxygen Booster is an air-powered pump (intensifier) designed to increase oxygen pressure for aircraft oxygen servicing carts and ground support applications. The unit boosts oxygen pressure to 2,500 PSI with only 80 PSI of drive pressure, making it an efficient solution for aircraft maintenance operations.
Oxygen boosters recover gas from low-pressure cylinders and compress it to higher pressures, allowing operators to utilize significantly more gas from each bottle. The OB-30 can deliver up to 75% more usable oxygen per cylinder, helping reduce gas waste, lower cylinder inventory requirements, and decrease servicing costs.
The integrated booster package includes essential monitoring and safety components, including drive regulation, oxygen pressure gauges, filtration, and automatic cut-in/cut-out pressure controls. Built with non-ferrous, oxygen-compatible materials, the OB-30 ensures safe, spark-free operation in demanding aviation environments. The booster can be mounted horizontally or vertically or installed on a two-, three-, or four-bottle aircraft oxygen servicing cart.

OB-30 Oxygen Booster – Recertification
The OB-30 Oxygen Booster must be inspected prior to each use to ensure proper operation and system safety. If inspection indicates potential contamination, component damage, or improper maintenance, the unit should be returned for professional inspection and recertification.
Per the manufacturer’s guidelines, the OB-30 must be recertified every two years or 1,500 operating hours, whichever occurs first. Following the recommended recertification schedule helps reduce the risk of contamination within the oxygen system, which could lead to dangerous ignition conditions.
During the IDI recertification process, the booster is fully inspected, cleaned, and rebuilt with new seals. Damaged or worn components are replaced, and oxygen-wetted parts are cleaned to restore safe operation. Older units may also receive updated components or safety enhancements.
Additional Note
Operating and maintaining any high-pressure oxygen booster system requires strict adherence to safety procedures. Personnel responsible for operating the OB-30 should be familiar with the Installation, Operation, and Maintenance Manual as well as all applicable aircraft servicing procedures.
All components used in the oxygen servicing system must be oxygen-compatible and pressure-rated for the application. When servicing aircraft oxygen systems, operators should follow all safety precautions, including proper equipment inspection, cleaning tools, and the use of required personal protective equipment, in accordance with company policies and applicable safety regulations, such as OSHA.

QUESTIONS & ANSWERS
No. For safety reasons, the OB-30 Oxygen Booster should never be left unattended while in operation. Even though the unit is designed for controlled high-pressure oxygen transfer, running it without supervision creates a risk of property damage or serious injury. Operators must remain present at all times to monitor gauges, connections, and pressure levels during use.
Interface Devices, Inc. (IDI) provides a one-year factory warranty covering defects in materials and workmanship under normal use and service. The warranty begins on the date of shipment from the factory. Claims outside this period are not covered, and all warranty returns must be pre-authorized by IDI before acceptance. For the most accurate warranty details, always refer to your OB-30 Operation & Maintenance Manual.
Yes! PJi can coordinate the recertification process for the OB-30 Oxygen Booster when required. The unit ships in specialized, high-strength packaging, and it’s recommended to retain this packaging for future certifications or returns. Contact our aviation support team when you are ready, and we’ll guide you through the process to ensure compliance and safe operation.
Preventative maintenance for the OB-30 should always be carried out by qualified technicians trained in high-pressure oxygen systems. Tasks must follow all applicable safety codes related to oxygen handling, installation, and troubleshooting. The Operation & Maintenance Manual provides a detailed preventative maintenance schedule, including inspections, lubrication, and replacement intervals. Following these guidelines will help extend the booster’s service life and ensure safe, reliable performance.
The OB-30 is powered by compressed gas and can run on either shop air or a nitrogen bottle. Both options deliver the necessary drive air to boost oxygen pressure efficiently. This flexibility makes the OB-30 suitable for different hangar and field environments, giving operators more versatility in aircraft oxygen servicing.
The OB-30 Oxygen Booster is equipped with dual 10-micron filters on the oxygen inlet and outlet ports. These filters help protect the system from contaminants that could compromise oxygen purity or damage sensitive booster components. Routine inspection and replacement of filters, per the manual’s guidelines, is an important part of ongoing maintenance.
Yes. The OB-30 Oxygen Booster is compatible with most 3-bottle and 4-bottle oxygen carts used in aviation ground support. Its compact footprint and -4 JIC connections make it easy to integrate into existing oxygen service setups. Always follow installation instructions and safety standards when mounting the booster to ensure stable and reliable operation.
Yes! The OB-30 Oxygen Booster is CE-rated and meets strict international standards for equipment safety and compliance. Additionally, all oxygen-wetted parts are cleaned and certified in accordance with ARP 1176 specifications, ensuring safe use in oxygen systems where contamination risks must be eliminated.
For optimal performance and safety, IDI specifies the following high-pressure oxygen hoses as replacements for the OB-30 Oxygen Booster:
- SS3000-25-25-72-O2 – Oxygen Hose, 3,000 PSI, -4 JIC Female, stainless steel, 6 ft, oxygen-cleaned
- SS30025-25-48-O2 – Oxygen Hose, 3,000 PSI, -4 JIC Female, stainless steel, 4 ft, oxygen-cleaned
Always use oxygen-cleaned, high-pressure-rated hoses that meet IDI’s specifications to maintain system integrity.
The OB-30 oxygen booster is designed to be powered by clean, dry nitrogen or filtered, dry compressed air (shop air) to ensure safe and reliable performance. At a drive pressure of 80 PSI, the unit produces approximately 2,200 PSI of oxygen pressure, making it suitable for a wide range of aircraft oxygen servicing tasks. However, the drive supply should never exceed 125 PSIG, as this could compromise both safety and performance.
