Fans

Fans 170mm 24V 1.70A EFB1524VHG Case Fan

SKU CH-V8RE-F04CJ

A 170 mm case fan delivering 325.0 CFM at 4300 RPM with double ball bearings for 180000 hours of continuous operation

  • High airflow 325.0 CFM for effective cooling
  • Double ball bearing rated 180,000 hours continuous life
  • 24 V operation with 12–28 VDC range
  • Aluminium frame and plastic blades weigh 1.9 pounds
  • 63 dB noise at 4300 RPM with 1.083 inH₂O static pressure

Delta 170mm 24V industrial fan

This 170mm case fan runs on 24V DC and draws 1.70A at full speed. It is built for servers, telecom cabinets and industrial enclosures that need high static pressure in a compact frame. The double ball bearing and aluminium housing support continuous operation in demanding environments.

Upgrade from lower-airflow 12V units

Replacing a standard 12V fan with this model raises airflow to 325.0 CFM and static pressure to 1.083 inches of water column. The jump is worth it when equipment generates more heat than the original cooling can remove, or when a single fan must move air through dense filter media or restricted ducting.

Two-lead wiring fits existing 24V rails

The fan terminates in two leads for direct connection to a 24V supply rail between 12V and 28V DC. Polarity must be observed; reversed wiring will prevent rotation. The 50mm thickness requires verification of mounting clearance, and the 63 dB(A) noise level suits rack rooms rather than quiet offices.

Questions about this item

Will the 170mm by 150mm frame with 50mm depth fit my 170mm case mount?

The fan measures 170 by 150 by 50mm, so verify your chassis has a 170mm square mounting pattern and at least 50mm clearance behind the panel.

How do I connect the two bare leads to a 24V supply without reversing polarity?

Connect the leads to a 12 to 28VDC source rated for at least 1.70A; the fan draws 1.17A typical and 1.70A max, so check polarity before powering.

When should I plan to replace the double ball bearing fan?

The bearing is rated for 180000 hours of continuous operation at up to 70°C, so schedule replacement once runtime approaches that figure.
