Zyvpee 7114NHR 170mm 24Vdc 19W 2 Pin Case Fan

170 mm 24 V DC axial fan for industrial cases

The Zyvpee 7114NHR is a 170 mm all-metal axial cooler designed for 24 V DC systems. It draws 19 W at a fixed 3350 RPM using a two-ball bearing. The two-pin connector suits power supplies without PWM control. Builders integrating ABB inverter gear or similar 24 V infrastructure will find it a direct fit.

Fixed-speed 24 V supply limits speed control

The fan runs at a constant 3350 RPM whenever 24 V is present. No PWM or voltage-regulation header is provided on the two-pin lead, so speed cannot be adjusted from a motherboard. Systems requiring variable airflow must implement external voltage control. The 19 W draw also demands a 24 V source rated for at least that continuous load.

Replaces 172 mm metal-frame fans in 24 V enclosures

This unit fits the 172 mm by 150 mm by 38 mm footprint common in legacy ABB inverter cabinets. It upgrades older sleeve-bearing models that have worn out or become noisy. The jump is worthwhile when the original fan fails or when a two-ball bearing is preferred for longer service life in continuous operation.
