EasyPro Alumina Airstones

• 3 times stronger than white silica airstones.
• Produces a finer bubble with no increase in pressure.
• Inlet fittings are set into the body of the diffuser, making them much less likely to break or twist.
• Higher density means self weighting.
• Cleanable with muriatic acid or chlorine.
• More ozone resistant.

Membrane Diffuser

Membrane diffusers are a great alternative to airstones in many aeration applications. Membranse have hundreds of "I" slots that open as air pressure builds inside of the diffuser. The center of the membrane does not have slots and acts as a check valve when air flow stops. Diffusers have a 3/4" male thread inlet and are 10 1/2" in diameter. Completely corrosion resistant. Up to 3 CFM air flow.

Tubular Diffuser

• Tubular membrane diffusers are 24" long, 2.5" in diamemter and have 8400 bubble-producing slots.
• Rated for 7 CFM
• Self weighted- open ended design allows diffuser to be self weighted.
• Built in check valve
• 3/4" stainless male threaded connection
