Aeration » Air Diffusers

Alumina Airstones 

• 3 times stronger than white silica airstones! 
• A finer bubble is produced with no increase in pressure 
• Less likely to break or twist loose, because Inlet fittings are set into the body of the diffuser 
• Higher density means self weighting
• Cleanable with chlorine or muratic acid 
• More resistant to ozone

Membrane Diffuser

An alternative to airstones are flo-disc membrane diffusers. As air pressure builds inside of the diffuser, membranes have hundreds of “I” slots which open.  The membrane’s center does not have slots and acts as a check valve when air flow stops.

Features:

• Have a ¾” male thread inlet and are 10 ½” in diameter.
• Uniform bubble distribution
• Built-in check valve, with up to 3 CFM air flow
• Heavy-duty membrane thst will last for years, completely corrosion resistant
• Removable membrane allows for cleaning or inspection inside diffuser

Rubber Membrane Air Diffusers

• Incredibly strong 
• Ideal for pond aeration, circulation & destratisfying applications 
• These EPDM membrane diffusers easy to clean, than the porous air stones 
• Produce more circulation & water movement 
• Have barbed inlets multiple size barbs. 
• Produce slightly larger air bubble than air stones which means less oxygen transfer into the water. For fish holding tanks, raceways, fish production ponds etc... air stones are recommended

Tubular Diffuser

• Tubular membrane diffusers are 24” L x 2½” diameter
• 8400 bubble producing slots.
• Rated for up to 7 CFM
• Self weighted (open ended design allows diffuser to be self weighted)
• Built-in check valve
• Durable & will provide years of service with minimal service
• ¾” stainless male threaded connection
