The blower fantwo inches of pure airflow engineeringhas become the versatile workhorse of 24V DC cooling solutions. With a compact footprint, it seamlessly replaces stock part-cooling fans on Ender 3/Pro printers. Its centrifugal impeller delivers double the static pressure of standard blowers, enabling cooler bridges, sharper overhangs, and eliminated heat creep at PETG temperatures. Makers initially upgrading their Ender's cooling soon deploy it across Vorons, CR-10s, and fume extraction systems in well-ventilated enclosures.
This 24V DC blower's adaptability stems from optimized engineering: Sleeve bearings ensure cost-effective durability
Precision-balanced rotor maintains noise 36 dB at full speed
Laminar airflow projects 15 cmideal for volcano nozzles or RAM heatsinks
Installation is plug-and-play: 200mm/250mm lead with keyed 2-pin JST connector (no polarity confusion)
Low current draw allows dual-fan daisy-chaining on 1A PSUs
15 mm profile preserves clearance for BLTouch/LED accessories
The ecosystem expands with three standardized sizes: 4010 blower fan (40×10 mm) - For compact DVR/router cases
4015 blower fan (40×15 mm) - Balanced flow for electronics aux-cooling
5015 blower fan (50×15 mm) - High-pressure hotend/duct solutions
All variants share: 24V DC operation (no buck converters needed)
Sleeve bearing construction
Unified 2-pin JST connectivity
Identical bolt patterns for drop-in upgrades
