Two fans are better than one. The Zephyrus Fan Duct adds an additional 5015 blower fan to the Prusa Mk3s+ Hotend with minimal changes to the original toolhead. Allowing better cooling performance and a more rigid design compared to other available fan ducts.

Optimized Design

  • Airpath has been drastically redesigned allowing less restricted airflow

  • Flow dividers splits each fan output into two separate nozzles and acts as build in support for printing

Directed Cooling

  • Air exits from 4 tuned micro ducts aimed directly at the nozzle tip

  • Fan ducts sits a mere 1.10mm taller than tip of the nozzle ensuring maximum airflow to nozzle tip

Easy Assembly

  • All hardware are reused from original Prusa Fan Duct and Spare Parts Bag

  • Print the Zephyrus Duct and the new extruder cover and you’re ready to go
