GDSTIME 24 V 4020 Sleeve Centrifugal Blower Fan

GDSTIME 24 V centrifugal blower in a 4020 format, with a sleeve bearing and an approximately 20 cm cable. Its 20 mm thickness provides static pressure in a compact assembly suitable for nozzles, air ducts and localised cooling.

Conditional compatibility

Dimensionally compatible with brackets designed for a 4020 blower when outlet orientation, mounting holes, available space and the 24 V connection match.

Do not confuse it with a 4020 axial fan or a 12 V version. It must not be presented as equivalent to a ball-bearing version because its bearing system and long-term behaviour differ.

Applications

• Part cooling through a duct.
• Localised electronics cooling.
• Compact air ducts requiring more thickness than a 4010 blower.
• 24 V cooling projects.

Control and installation

• Confirm that the controller output supports its current.
• Check polarity and connector before applying power.
• Keep the circular air inlet unobstructed.
• Avoid sharp bends or restrictions in the duct.
• Check reliable starting when using low-duty PWM control.
• Do not use images of the ball-bearing variant as a reference for this sleeve model.
