Dual 5010 Blower Kit for LONGER Printers

This dual blower kit upgrades the part-cooling system on LONGER LK1, LK4, LK4 PRO and LK5 PRO machines as well as Alfawise U20, U30 and U30 PRO printers. Two 5010 fans direct focused airflow onto freshly extruded filament to reduce deformation and stringing during printing.

Suited for owners of the listed LONGER

Makers who need stronger part cooling on these specific printers will benefit from the dual-fan layout. Builders using other printer brands or models not named in the compatibility list should look for a kit designed for their hardware.

Sustained cooling during long prints

The dual 5010 arrangement maintains steady airflow across the nozzle throughout extended jobs, helping each layer solidify before the next is laid down. Consistent cooling reduces warping and stringing that can appear when a single fan cannot keep up over many hours.

Highlights

  • Faster cooling reduces deformation and stringing after extrusion
  • Dual blower design delivers stronger airflow than single-fan setups
  • 5010 form factor fits LK1, LK4, LK4 PRO, LK5 PRO printers
  • Also compatible with Alfawise U20, U30, U30 PRO models
  • New condition ensures full performance from first print
