This 1/2" I.D. weighted diffuser tubing is useful in applications where long lengths are required. Equal bubble distribution is possible with lengths as long as 25' for WD50. On the WD50, unique die cut slits located in sets of three every 1 1/2" flex open with air pressure and close when air is stopped.
This weighted tubing requires WD fittings. Full rolls are 250' long (60 meters). This diffuser tubing is not compatible with most regenerative blowers as 2–5 psi is required. Also note that this coarse bubble diffuser tubing will only provide about one-third as much oxygen transfer per cfm of air as Sweetwater® diffusers.
Note: Diffusers are also known as airstones. Tubing is also known as hose.
