AC centrifugal fan for industrial airflow

The Fans R3G140 is a new AC centrifugal fan rated for 220 V operation. It draws 1.1 A and delivers 110 W of power. The unit is built on an ebm-papst platform with a compact external-rotor motor and sturdy steel-plate construction. It is suited for forced electronic cooling in enclosures that require high static pressure.

Installers needing mains-powered centrifugal cooling

This fan suits engineers integrating mains-voltage airflow into rack cabinets, telecom shelters or industrial chassis. It is not for builders who need a low-voltage PWM case fan for a desktop motherboard header. Buyers who require variable speed via analog or serial control should verify their controller compatibility before purchase.

2447 FFU model identifier confirms fit

The 2447 FFU designation is the single specification that determines whether this unit matches the mounting pattern and airflow curve of the target system. Cross-reference this code against your equipment bill of materials to ensure mechanical and electrical compatibility.
