Industrial axial fan for 24 V systems

The COMROTON COMAIR PQ24B7X is a 172 mm square axial fan built for 24 V DC power. It draws 1.0 A and runs at 3550 rpm to move 8 m³/min of air through server chassis or industrial enclosures. The high-precision ball bearing supports continuous operation in equipment that demands steady airflow.

20 W draw with 65 dB output

At full speed the fan consumes 20 W while producing a measured noise level of 65 dB. The 51 mm frame depth fits standard 170 mm mounting patterns without protruding beyond typical rack clearances. Thermal load scales directly with the 24 V supply, so acoustic output remains consistent in normal use.

Ball bearing extends service interval

The high-precision ball bearing reduces friction compared with sleeve designs, lowering wear during 24/7 duty cycles. No speed-control cable or PWM header is included, so the unit runs at fixed voltage. Installers should verify 24 V availability and the 170 mm hole pattern before fitting.

Questions about this item

How do I mount the 172 mm square fan with 51 mm depth in my chassis?

Align the four corner holes with your case fan mounts, use the supplied screws, and ensure the airflow arrow points toward the interior; the 51 mm thickness can block adjacent drive cages if not checked first.

When will the high-precision ball bearing need replacement under continuous 24 V operation?

The ball bearing is rated for long life at 3550 RPM, but dust buildup on the blades increases load; clean the rotor every six months and plan bearing replacement once noise rises above the specified 65 dB level.

At what point does the 20 W motor hit its thermal limit during sustained 3550 RPM running?

The 24 V 1.0 A design delivers 8 m³/min airflow until internal winding temperature reaches its rated ceiling; in restricted enclosures this limit appears first as reduced RPM and rising noise.
