About this product
The 2215627-2 is a secondary heat-exchanger diffuser. Installed in the air cycle machine of an aircraft’s environmental control systems, it receives high-velocity, cooled air from the primary heat exchanger and converts dynamic pressure into static pressure to promote uniform airflow through the secondary core.

PRODUCT DESCRIPTION

2215627-2

  • Optimised Flow Geometry: Precision-machined vanes diffuse incoming air uniformly, minimising turbulence and enhancing heat-exchange efficiency.

  • High-Temperature Resistance: Constructed from stainless-steel alloys rated for continuous exposure to bleed-air temperatures up to 260 °C.

  • Corrosion-Resistant Finish: Internal surfaces feature protective coatings to resist oxidation and erosion from moisture and contaminants.

  • Low Pressure-Drop Design: Engineered to maintain system performance by converting velocity to pressure with minimal loss, preserving pack cooling capacity.


  • Uniformly distributing conditioned air through the secondary heat exchanger in ECS packs.

  • Converting airflow velocity into static pressure for improved cabin temperature control.

  • Supporting in-flight cooling operations during high-thermal-load phases, such as takeoff and climb.

  • Serving as a direct replacement in maintenance programs requiring FAA/EASA dual-release components.


  • What role does this diffuser play in the air cycle machine?

It slows and spreads the flow of cooled air from the primary heat exchanger to ensure even passage through the secondary core.

  • How does corrosion resistance benefit the diffuser?

Protective coatings guard against moisture and particulate erosion, extending service life and maintaining efficiency.

  • What certifications confirm its airworthiness?

It carries dual-release FAA 8130-3 and EASA Form 1 documentation, ensuring global regulatory acceptance.
