Compare to Non-corrugated Flex Pipe
As mentioned earlier can you name the specific characteristics behind the "unfriendly airflow in flexible pipe" when chosen over the less limited in ply-ability (bend-ability) of Rigid,PVC, pipe.
I performed a study on clear, extremely flexible, lexan tubing with like ID & OD, with no corrugated ribbed design structure inside or out. Flex-tubing resembles more of a food grade look. Objects that fit through floor vac tool inlet side run their course perfectly if not using extreme curvature areas when installing clear flex tube around obstructions to main vac unit.
Are you referring to inner build up problems or humidity factors with corrugated structure tubing?
Hello, in traditional central vacuum flex pipe there is a corrugation that greatly inhibits airflow. Even our PVC pipe is quality controlled for interior smoothness because it has a dramatic affect. PVC is ideal for airflow because it can be extremely smooth compared to other transits over a hundred feet long with bends and all.
