Dayton 24V DC 45 CFM 2700 RPM Case Fan

SKU CH-P8SR-HMQRE

A 24 V DC case fan moves 45 CFM at 2700 RPM while drawing only 1.7 W and running at 33 dB

  • Product typeCase Fan
  • 24 V DC input simplifies low-voltage system wiring
  • 45 CFM airflow at zero static pressure delivers steady cooling
  • 2700 RPM ball-bearing motor runs quietly at 33 dBA
  • 7 W draw keeps energy use minimal
  • IP20 rating and 158 °F max ambient suit demanding environments

Square 24 V DC case fan

This square axial fan runs on 24 V DC and delivers 45 CFM at zero static pressure. It spins at 2700 RPM using a brushless DC motor with ball bearings. The unit draws 0.07 A and consumes 1.7 W while producing a sound level of 33 dB. Its IP20 rating and impedance thermal protection suit industrial and embedded cooling tasks.

Replaces lower-airflow 24 V fans

The 45 CFM output upgrades setups that currently move less air at the same voltage and mounting pattern. A jump is worthwhile when the existing fan cannot meet thermal demands at 0.000-In. SP or when acoustic targets require the 33 dB rating. The brushless motor and ball bearing design also extend service life compared with sleeve-bearing alternatives.

Check voltage wiring and mounting centres

Verify that your system supplies 24 V DC and can accommodate lead-wire electrical connections. Confirm the 3 1/4 in mounting eye centre-to-centre spacing matches your chassis or panel cut-out. Ensure the 1 in depth and 3 5/8 in square footprint fit the available space and that the maximum ambient temperature of 158 °F is not exceeded.

Questions about this item

What are the mounting hole centres for the 3-5/8 inch square frame?

The mounting eye centres are 3 1/4 inches apart, allowing vertical or horizontal installation on standard fan mounts.

How do I connect the lead wires to a 24 V DC supply without reversing polarity?

Connect the positive lead to 24 V DC and the negative to ground; the brushless motor draws 0.07 A at 1.7 W and includes impedance thermal protection.

When should I expect to replace the ball-bearing fan rated for 158 °F ambient?

Ball bearings typically last several years at 2700 RPM; monitor for rising noise above the 33 dB baseline or reduced airflow from the 45 CFM rating.
