Product description SXDE1238MB · BRUSHLESS EC 120mm EC axial cooling fan. 120 × 120 × 38 mm frame.

The SXDOOL SXDE1238MB is a 120mm EC cooling fan with dual ball bearings and a 120 x 120 x 38 mm frame. Its label specifies 115/230 V AC at 50/60 Hz and 8 W. Check the frame and supply and connection against your equipment requirements.

• What does EC mean in an EC cooling fan?

  EC means electronically commutated. This brushless EC motor fan uses AC input; its label specifies 115/230 V AC, 50/60 Hz and 8 W.

• Will this 120mm fan fit my enclosure?

  The frame measures 120 x 120 x 38 mm, approximately 4.72 x 4.72 x 1.50 inches. Verify mounting points and lead-wire clearance. A 120mm frame alone does not establish replacement compatibility.

• Is this a quiet fan?

  No. This is not a quiet fan. Consider the operating sound before choosing it for a noise-sensitive space. Sound levels vary with installation and operating conditions.

• Can I use it for cabinet ventilation through a filter?

  Filters and grilles add resistance to airflow. Suitability depends on the airflow required by the equipment and the resistance of the installed ventilation path; confirm these requirements before installation.

• Is this a plug-in or PWM computer fan?

  This model has two black lead wires for an AC connection. Do not treat it as a USB, 12V DC or four-pin PWM motherboard fan. Check supply ratings and required termination before installation.

EC means electronically commutated. This model uses AC input rated 115/230 V AC at 50/60 Hz and 8 W. Two black lead wires require a suitable termination. Check the equipment wiring instructions and supply ratings before installation. A lead-wire connection does not imply a plug-in connector. Disconnect power before handling or wiring.

Cabinet and enclosure ventilation. Start with the right fit.

1. Equipment enclosure cooling

   Check mounting points and allow space for the 120 x 120 x 38 mm frame and lead wires. Match the electrical supply and airflow requirements.

2. Automation control cabinet cooling

   Confirm the equipment supply matches the 115/230 V AC and 50/60 Hz label ratings. Follow the equipment wiring instructions and ventilation requirements.

3. Electronic equipment ventilation

   For instrument chassis ventilation projects check the airflow path and available clearance. Account for resistance from grilles or filters before choosing the fan.

4. CNC equipment enclosure cooling

   Plan ventilation for an indoor CNC electrical enclosure. Verify mounting clearance supply ratings and the required airflow before selecting the fan.

5. Network rack ventilation

   For an indoor rack ventilation enclosure. Check AC supply compatibility and mounting space. Keep cable routing clear of the fan and the ventilation path.

6. Lighting equipment ventilation

   An indoor lighting-equipment ventilation concept. Check the fixture design and fan ratings before installation. Disconnect power before servicing.

Illustrative installation concepts. Equipment shown is not included. Application suitability depends on the equipment design and installation requirements.
