PSU, Lights, O2 Containers and Gaspers

We provide certified repair, overhaul, and replacement services for Passenger Service Units, cabin lighting systems, oxygen containers, and gasper assemblies on commercial and executive aircraft.

Passenger Service Unit Repair, Overhaul, and Component Support

AIRO Industries Company provides complete services for the overhead passenger service systems that run the length of every commercial aircraft cabin. These systems include the Passenger Service Units that house reading lights, attendant call buttons, oxygen mask compartments, no smoking and fasten seatbelt signs, and individual air gaspers. They are among the most used and most visible components in the cabin, and keeping them in working order is essential to both passenger experience and regulatory compliance.

Our team handles the full range of PSU components, cabin lighting systems, portable and fixed oxygen containers, and gasper assemblies across Boeing and Airbus platforms. Whether the requirement is a single component swap or a complete overhead system overhaul during a cabin refurbishment, we deliver the parts, the labor, and the FAA documentation to get it done.

Passenger Service Unit repair and overhaul

Cabin lighting system service and LED upgrades

Oxygen container inspection, hydrostatic testing, and replacement

Gasper assembly repair and replacement with full FAA documentation

We service PSU housings, latch mechanisms, hinge assemblies, lens covers, and internal wiring. Our work covers cosmetic restoration for scuffed or discolored housings as well as functional repair of broken latches, cracked lenses, and failed electrical connections. Every PSU is returned to service in full working condition with documentation.

PASSENGER SERVICE UNITS (PSU)

PSU services include:

The Passenger Service Unit is the integrated overhead panel that passengers interact with throughout every flight. It houses multiple systems in a compact enclosure, and each component must function reliably while maintaining a clean, uniform appearance across the cabin. AIRO Industries Company repairs, overhauls, and replaces PSU assemblies and their individual components for both narrow body and wide body aircraft.

CABIN LIGHTING

Cabin lighting sets the tone for the entire passenger experience, from boarding to arrival. AIRO Industries Company provides repair, replacement, and upgrade services for all cabin lighting systems, including fluorescent and LED main cabin lights, sidewall wash lights, entry and exit lights, floor path emergency lighting, and individual reading lights mounted in the PSU.

Cabin Lighting services include:

Main cabin ceiling light repair and replacement

Sidewall wash light and accent light service

Reading light repair and bulb or LED replacement

IFE monitor mounting and integration support

Floor path emergency lighting inspection and service

Entry, exit, and galley area lighting

OXYGEN CONTAINERS

Passenger and crew oxygen systems are life safety equipment with strict inspection, testing, and replacement intervals. AIRO Industries Company provides full service support for portable oxygen bottles, fixed oxygen containers, chemical oxygen generators, and the associated masks, tubing, and deployment mechanisms housed inside the PSU.

Oxygen Container services include:

Portable oxygen bottle inspection and hydrostatic testing

Fixed oxygen container service and replacement

Chemical oxygen generator inspection and exchange

Oxygen mask and tubing inspection and replacement

Regulator and flow control valve service

Mask deployment mechanism and PSU door coordination

OXYGEN CONTAINERS

Gaspers are the individual air outlets mounted in the PSU that allow passengers to direct conditioned air to their seating position. These small but essential components see constant use and are prone to mechanical wear, sticking, and breakage over time. A row of non-functional gaspers is one of the most common passenger complaints in any cabin.

Oxygen Container services include:

Gasper nozzle and ball joint repair

Valve mechanism overhaul and replacement

Duct connection and air supply fitting service

Complete gasper assembly replacement

Coordination with PSU and overhead panel programs

Frequently Asked Questions

Some frequently asked questions about the service that you may have questions about

What components are inside a Passenger Service Unit?

A typical PSU contains reading lights, an attendant call button, no smoking and fasten seatbelt indicators, an oxygen mask compartment with deployment door, and individual air gasper outlets. The exact configuration varies by aircraft type and operator.

Do you support LED cabin lighting upgrades?

Yes. We provide fluorescent to LED conversion programs that deliver lower power consumption, longer service life, and the ability to implement mood lighting. LED upgrades can be performed as a standalone project or as part of a complete cabin interior refurbishment.

What oxygen system services do you provide?

We provide portable oxygen bottle inspection and hydrostatic testing, fixed oxygen container service and replacement, chemical oxygen generator exchange, mask and tubing replacement, and regulator service. All work is performed in accordance with FAA requirements and manufacturer maintenance schedules.

Can PSU and overhead work be performed during a cabin refurbishment?

Yes. PSU repair, lighting upgrades, oxygen system service, and gasper replacement are frequently performed as part of complete cabin interior programs. Coordinating this work during a single maintenance event reduces total aircraft downtime.

Do you supply both new and overhauled PSU components?

Yes. We provide both new and overhauled PSU components, gasper assemblies, lighting units, and oxygen system parts, all delivered with the required serviceability documentation.

Which aircraft platforms do you support for overhead systems?

We support Boeing and Airbus commercial aircraft as well as selected executive and special mission platforms. Configuration support depends on aircraft type and operator requirements.
