Q: Do you source bleed air system components for Boeing/Airbus?

Yes — bleed air system components for Boeing (737, 757, 767, 777) and Airbus (A320, A330, A340, A380) are available through our sourcing network. Common parts: pre-cooler isolation valve (PCV), HP bleed valve, bleed regulator, and associated ducting. Exchange and overhauled units available.

Q: Can you supply pneumatic ducting in Inconel or titanium?

Yes — we source Inconel pneumatic ducting per AS18280 and AS1895 specs, and titanium per AMS 4901. Available sizes range from -4 to -20. Ducting ships with pressure-test certification from the manufacturing facility. Custom lengths are available through our supplier network.

Q: Do you have outflow valve assemblies in stock?

Outflow valve assemblies are typically exchange items — we have availability for Gulfstream (G550, G650, G500) and are sourcing for Boeing/Airbus platforms. Submit a part number and aircraft type for availability check. The outflow valve is a critical pressurization safety item and requires 8130-3 plus test data.

Q: What is the lead time on pneumatic system components?

In-stock exchange units ship within 3–5 business days. Sourced overhauled units typically run 2–6 weeks depending on platform and sourcing complexity. AOG requests are prioritized — we maintain emergency sourcing contacts for bleed system failures.

Q: Do you supply air cycle machine (ACM) components?

Yes — ACM turbine wheels, compressor wheels, seals, bearings, and ACM controller units are sourced for Boeing/Airbus and corporate aircraft ECS systems. Full ACM exchange is available for some platforms. Major ACM overhaul requires specialized shops — we can source to qualified repair stations or provide exchange units.

What We Source

Pneumatic systems on modern aircraft serve three purposes: engine bleed air for ECS (environmental control system), anti-icing (wing and engine inlet), and backup pneumatic power for hydraulic reservoirs and starter systems. Components range from titanium ducting and clamp rings to complex air cycle machines and pressurization controllers.

The most common procurement scenario is ECS/pressurization problems: outflow valve failure, bleed valve actuator wear, pressurization controller fault, or ducting chafing on a phase inspection. For these situations, exchange and overhauled units are the fastest and most cost-effective path.

System Overview by Platform

Boeing 737/757/767/777

HP bleed air from the compressor section at ~45 PSI. Pre-cooler (heat exchanger) reduces temperature to ~390 deg F. HP valve (HPV) controls bleed pressure to the Pneumatic Distribution System (PDS). Common failure items: HPV actuator, PCV (pre-cooler valve), bleed regulator, and ducting chafing near hot sections.

Airbus A320 Family / A330 / A340

ECAM-controlled bleed system. Three independently-controlled bleed sources (ENG1, ENG2, APU, or HP ground cart). HPV and PRV (Pressure Regulation Valve) control flow. Common: bleed monitoring computer (BMC), HP valve, ducting sensor failures.

Gulfstream G550 / G650

Engine bleed air (HP and LP ports), APU bleed, and external air connection. Pre-cooler and HPV control bleed to ECS. Pressurization controlled by outflow valve motor driven by the pressurization controller. Common: outflow valve motor assembly, pressurization controller PCB, bleed valve actuator.

De-Ice / Anti-Ice Pneumatics

Piccolo tube pneumatic de-ice systems on wings and tail. Boot-type de-ice systems (pneumatic inflation of rubber boots). Boot control valves and timer switches. Common: boot valve failure, timer/relay faults, pneumatic line chafing.

Certification

All pneumatic system components (valves, actuators, controllers) come with 8130-3 or EASA Form 1. Ducting ships with pressure-test certificates from the manufacturing facility. Outflow valve exchange includes functional test data from the exchange facility.
