Roots blower for near field cooling
thingiverse
Air flowing into a tube must push past a printer nozzle's restrictive pathway, requiring a stronger force than either axial or centrifugal fan output can deliver. However, pistons and diaphragm pumps supply even greater pressure that goes beyond what this simple blower setup needs. The design, rooted in Roots blowers, fits this niche application by sending 15l/min through 8mm bore silicone tubing along a one-meter span with ease. The manual resides within a PDF document nestled in the source directory. Note: Two rotors are necessary for successful assembly and function.
