This model is designed for DIY assembly, allowing you to install a ducting shroud on the SanAce 40 4028 fan.

It can also be used for exhaust ventilation in moxibustion devices, with a diameter of 40 mm.

When paired with a printer’s ducting shroud, it effectively extracts fumes and exhaust gases from the printer, helping maintain good air quality in the printer’s operating environment.

The SanAce 4028 fan is available either as a brand-new unit or as a refurbished, disassembled fan—both options are quick and convenient. We recommend opting for the refurbished version, which typically costs only a few yuan.
