CPAP Fan Pipe 1.8M Soft for WS7040

This is our carefully selected Fan pipe for use with the WS7040 blower.

It has enough softness to reduce resistance during movement, and the shell design that does not fold in half avoids blocking the Fan pipe.
You need to design a print for this air tube to connect to the WS7040, VzBoT has this design and you can find the print at this URL: https://github.com/VzBoT3D
