Air Start Units (ASUs) – High‑Performance Aircraft Engine Starting Solution

An Air Start Unit (ASU) is an essential piece of aircraft ground support equipment (GSE) designed to deliver high‑pressure, high‑volume compressed air for safe and efficient turbine engine starting. Engineered for reliability and performance, our ASU solutions support a wide range of commercial, military, and private aircraft, ensuring dependable engine starts even when onboard APUs are unavailable or maintenance‑restricted.

What Is an Air Start Unit?

An Air Start Unit provides the  Continuous Flow required to rotate an aircraft’s engine during the start sequence. By supplying controlled, high‑pressure airflow directly to the aircraft’s starter system, the ASU eliminates the need for APU usage, reducing fuel consumption, emissions, and operational costs.

Key Features & Benefits

•  High‑capacity airflow for rapid and reliable engine starts

•  Diesel or electric power options to match your operational environment

•  Durable, weather‑resistant construction for continuous ramp operations

•  Advanced pressure regulation for safe and stable  Continuous Flow output

•  Low‑maintenance design that maximizes uptime and reduces service costs

•  Compatible with major aircraft types, including narrow‑body, wide‑body, and military platforms

Ideal for Aviation Operations

Our ASUs are trusted by:

•  International airports

•  MRO (Maintenance, Repair & Overhaul) facilities

•  Military airbases

•  Remote airfields and off‑grid operations

Whether you’re supporting daily flight operations or specialized maintenance tasks, an ASU ensures your aircraft engines start smoothly, safely, and efficiently.
