CAAC FAA 8130-3 TRIPLE RELEASE

Description

<h4>Applications</h4><p><strong>APUs</strong>: Honeywell GTCP36-150 series and GTCP331 variants for oil cooling.</p><p><strong>Aircraft</strong>: Gulfstream G-IV, GIV-SP, G-400, G-300; Bombardier Learjet variants with Honeywell APUs. Used in APU cooling systems for sustained ground power and in-flight backup.<br></p><p>The 3884629-5 is a Honeywell cooling fan assembly (often abbreviated OCLR for oil cooler), integral to APU thermal management. This axial fan unit circulates air over heat exchangers, dissipating heat from oil or fuel systems to maintain optimal temperatures during APU operation. It operates on 28V DC, delivering airflow rates of 200-400 CFM with low noise (under 70 dB) and variable speed control via the ECU. Constructed with lightweight composite blades and aluminum housing, it's designed for efficiency and longevity (weight ~5-8 lbs).</p>
