SKU CH-QK8Z-41RDT

A 40 mm axial fan running on 24 V and drawing 0.09 A for compact enclosure cooling

  • 24 V power supply simplifies wiring in industrial equipment
  • 09 A draw keeps energy use low for continuous operation
  • Two-wire design allows quick installation without extra connectors
  • 4020 frame size fits standard 40 × 20 mm mounting points
  • Original ADDA build delivers reliable cooling for medical and rail applications

Compact 24V 4020 fan for tight builds

This 24-volt axial fan fits the 4020 form factor and draws only 0.09 amps, making it suited to small enclosures, industrial controllers or inverter cooling where space and power budget are limited. The two-wire design keeps wiring simple for OEM integration.

Two-wire connection simplifies fitting

Installation is a matter of matching the two leads to a 24-volt supply; no PWM or tachometer wires are present so speed control and monitoring must be handled externally. The main risk is reversing polarity or feeding the wrong voltage, either of which will stop the fan or damage it.

Suited to low-power 24V systems.

Builders who need a basic 24-volt fan with minimal current draw will find this a direct fit. Buyers who require PWM speed control, tachometer feedback, higher static pressure or a different voltage should look at other models.
