Porous Plastic Diffuser Tubes
Aeration » Air Diffusers »
This semi-rigid, micro-porous, polyethylene diffuser tubing may be assembled into many configurations using regular PVC fittings and SIL2C clear silicone. This diffuser material produces fine bubbles (the pore size is 20-35 microns, so use a 10-micron air filter) with a pressure loss of about 15" H2O. Can be cleaned with muriatic acid. Very buoyant, so hold-downs or weights are required on this hydrophobic diffuser material. Sold in 1' increments. Made in USA.
