Heavy-Duty Replacement Membrane Diffuser for Large Pond AerationThe EasyPro REPLACEMENT Membrane Diffuser is a professional-grade, heavy-duty diffuser designed as a replacement for BDA and EBD4A aeration systems. Featuring hundreds of innovative "I" slots and a 10-inch diameter, this durable membrane diffuser provides uniform bubble distribution and reliable performance.Key Features Heavy-Duty Membrane: Built to last for years in continuous aeration applications Innovative "I" Slot Design: Hundreds of slots open as air pressure builds for optimal bubble release Built-In Check Valve: Center of membrane acts as a check valve when airflow stops, preventing backflow Uniform Bubble Distribution: Consistent bubble pattern with up to 3 CFM airflow capacity 10" Diameter: Large surface area for maximum aeration coverage 3/4" MPT Inlet: Standard male pipe thread connection for easy installation Specifications Diameter: 10 inches Inlet Connection: 3/4" male pipe thread (MPT) Maximum Airflow: Up to 3 CFM Material: Heavy-duty membrane Weight: 3 lbs Compatible Systems BDA Bottom Diffused Aeration Systems EBD4A Aeration Systems Other systems requiring 3/4" MPT diffusers FAQQ: Will this fit my aeration system?A: This diffuser is designed for BDA and EBD4A aeration systems with 3/4" MPT connections. Verify your system's connection size before ordering.Q: How long will this diffuser last?A: The heavy-duty membrane is built to last for years with proper use and maintenance. Lifespan depends on water conditions, airflow, and operating hours.Q: What is the maximum airflow this can handle?A: The diffuser provides uniform bubble distribution with up to 3 CFM (cubic feet per minute) of airflow.Q: How does the check valve work?A: The center of the membrane has no slots and acts as a one-way valve. When air pressure stops, this center section seals to prevent water from flowing back into the airline.Q: Can I use this to replace air stones?A: Yes, membrane diffusers are an excellent alternative to air stones in many aeration applications, offering better longevity and easier maintenance.Q: How do I clean this diffuser?A: Remove the diffuser from the pond and rinse with clean water. For stubborn buildup, gently scrub the membrane surface. The "I" slot design resists clogging better than traditional air stones.Q: Is this difficult to install?A: Installation is straightforward. Simply thread the 3/4" MPT inlet onto your airline fitting. Ensure a secure, leak-free connection.Q: Can I use multiple diffusers on one compressor?A: Yes, multiple diffusers can be run from a single compressor using a manifold, as long as the compressor has sufficient CFM capacity for all diffusers.
