High-performance DC tubeaxial fan from COMAIR ROTRON, Major DC series, model JQ24B4. Commonly used in UPS, power electronics, and industrial cabinets that require a 24 V DC 172 mm-class fan for main system cooling.
Rated for 24Â VÂ DC, ~1.0Â A, 24Â W, this ball-bearing fan delivers strong airflow (around 235Â CFM) and static pressure at approximately 3400Â RPM, helping keep transformers, rectifiers, and switching hardware within their safe operating temperature range.
Mechanical format matches the standard 171.5 × 150.4 × 50.8 mm (≈ 6.75 × 5.92 × 2.00 in) Major DC footprint with 2-terminal termination, making it a direct drop-in where JQ24B4 / 19031090A / 031090 is specified.
