Description
Japan Servo RH7-1047 CF24DM506-701 Vortex Blower 24VDC 2.4W Tangential Fan
The Japan Servo RH7-1047 is a compact vortex (tangential/crossflow) blower made by Japan Servo Co., Ltd. in Japan. Unlike conventional axial fans, a tangential blower draws air across the full width of a cylindrical impeller and exhausts it in a uniform, low-turbulence stream — making it well suited for applications where even airflow distribution and low acoustic output are important. The unit runs on 24V DC at 2.4W and comes mounted in a formed sheet-metal chassis with integral mounting flanges.

Applications
Tangential blowers like the RH7-1047 are commonly used in office equipment, copiers, printers, laser printers, medical devices, and electronic instrument chassis where a long, uniform airflow curtain is needed across a heat sink, fuser assembly, or circuit board array. The crossflow design produces a relatively flat velocity profile across the outlet width, which makes it useful for cooling components spread over a wide area rather than concentrating airflow in a single spot. At 24VDC and 2.4W, this unit is suited for low-power embedded systems, OEM equipment replacements, and custom cooling solutions. Japan Servo Co. has supplied precision motors and fans to OEM manufacturers in copier, printer, and precision instrument industries for decades, and the RH7-1047 format was a common building block in Japanese office equipment of the 1990s–2000s era.
This Japan Servo RH7-1047 CF24DM506-701 vortex blower is in good used condition. It was pulled from a working environment where it had been in service. The sheet-metal housing and mounting bracket show normal light wear consistent with use; the impeller, motor, and wiring leads appear intact with no obvious damage.
