Same great membrane diffuser performance now in a self sinking design

• Self weighted base with powder coated finish
• Self weighted design eliminates need for gravel, reduces installation time
• Sch. 80 PVC air manifold check valve
• Includes inlet air fittings for 3/8", 1/2" or 5/8" tubing; tubing clamps and strain relief
• Shown assembled with strain relief included for durability
• 5 Year Warranty

Additional Information:

• Recommend Flow Rate: 0.8-3.0 CFM

Tubular membrane diffusers are 24" long, 21/2" in diameter and have 8000 bubble producing slots

• Self weighted - unique open ended design allows diffuser to be self weighted
• Incredibly durable - will provide years of service
• 3/4" female threaded connection
• Built in check valve

These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfying applications

• Unlike air stones these diffusers are easy to clean
• In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, etc. we recommend staying with the air stones below
• Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using
• An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement

Additional Information:

• Recommended Air Flow (CFM): 1.8
• Maximum Air Flow (CFM): 5.4
• Inlet: 3/4"MPT

A great alternative to air stones in many aeration applications

• Hundreds of "I" slots that open as air pressure builds inside of the diffuser
• 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 101/2" in diameter
• Heavy duty membrane will last for years
• Uniform bubble distribution with up to 3 CFM air flow

• Polyethylene underlay keep diffusers from settling into the mud and prevents sediment erosion during operation
• Comes with 6" long Alumina Air Stones for better oxygen transfer with smaller bubbles than rubber membrane diffusers
• Includes check valve to prevent water from filling air line when not in use
• Includes tubing strain relief and fittings to connect to 3/8" or 1/2" ID tubing

Additional Information:

• Recommended Air Flow (CFM): 3.0 - 4.2
• Inlet: 3/8", 1/2", 5/8 barb
