The DB-36 High-Efficiency Diffuser is a premium, fine-bubble pond and lake aeration diffuser designed for maximum oxygen transfer and long-term durability. Built with stainless steel parts and hardware and industry-proven, high-quality fine-bubble diffuser tubing, it delivers consistent performance with low backpressure and minimal maintenance in continuous-duty aeration applications.

Product Overview

The DB-36 High-Efficiency Diffuser is a premium, fine-bubble diffuser designed for pond and lake aeration systems where performance, durability, and long service life matter. Manufactured in the USA, it is engineered to deliver high oxygen transfer efficiency while maintaining low backpressure, helping aeration compressors operate more efficiently over time.

Fine-Bubble Diffuser Technology

This diffuser uses high-quality, industry-proven fine-bubble diffuser tubing based on Aero-Tube® technology rather than standard membrane disc diffusers. The tubing produces uniform micro-bubbles along its full length, improving oxygen transfer while reducing the risk of clogging, hardening, or performance loss commonly associated with traditional membrane styles. This makes the DB-36 well suited for continuous-duty aeration in real-world pond and lake environments.

Durable Construction

The DB-36 is built with a self-weighted stainless steel base and stainless hardware to ensure long-term corrosion resistance and stable placement on the pond or lake bottom. Domestic manufacturing standards and material selection help ensure consistent quality, reliable performance, and long-term support.

System Compatibility

The DB-36 is compatible with most pond and lake aeration systems using compressors capable of delivering approximately 1 CFM or more. It can be used in a wide range of depth profiles and is suitable for both residential and commercial aeration installations.

Frequently Asked Questions

Q: Is this diffuser compatible with my aeration system?

A: The DB-36 High-Efficiency Diffuser is compatible with most pond and lake aeration systems using compressors capable of delivering approximately 1 CFM or more. It is suitable for both residential and commercial aeration applications across a wide range of pond depths.

 

Q: How long does the diffuser tubing last?

A: The fine-bubble diffuser tubing used in the DB-36 is designed for long service life in continuous-duty aeration systems. When properly installed and operated, it provides consistent performance for many years with minimal maintenance.

 

Q: What size diffuser should I choose for my pond or lake?

A: The DB-36 is ideal for medium-to-large ponds and lakes where higher airflow and efficient oxygen transfer are required. For smaller systems or lower airflow applications, SB-series diffusers may be a better fit.

 

Q: What is included with the diffuser?

A: The DB-36 diffuser includes the stainless steel diffuser base, fine-bubble diffuser tubing, stainless steel mounting hardware, an integrated check valve, and a 3/8″ hose barb. A 1/2″ hose barb is also included for flexible system integration. The DB-36 can be adapted to larger hose by purchasing a 1/2" NPT Male fitting with a barb appropriate for your selected tubing.

    Very well built

    Posted by josh on 11th May 2024

    I was immediately impressed with the build quality, all pieces fit together great and just really nice fit and finish all around. The "self sinking" feature is great. I was concerned about it sinking into the mud at the bottom so I placed it on a concrete block. Been on duty for a few weeks now, if it stops being awesome, I'll update the review.

    Very well made!

    Posted by Invar69 on 11th May 2024

    This is probably overkill for my goldfish pond but when I got it, I was impressed at how well made it was! It was well packaged and easy to assemble and I liked it included both 3/8" and 1/2" barbed adapters. The reversible OD 1" or 3/4" strain-relief hose bracket is a nice touch! I really liked that there was a 3/8" connection hole in the middle so you can tie a rope to it. It works great and I do wish the company might consider making a smaller one.

    Best I've dealt with

    Posted by Thomas Donley on 12th Jul 2023

    You folks are absolutely the best on-line business I've ever dealt with! Within 3 hours of ordering, I received notification that UPS had received the product I ordered and had it in transit already. That, without doubt, is truly rare and exceptional customer service! Having previously purchased one of your diffusers from a local supplier, I can also affirm that the quality of your products far surpasses those from all other diffuser manufacturers. Thank you for the integrity this organization brings to it's business operations, and rest assured that every pond-owning friend I know has already been shown my two US Solar diffusers, the DB-36 and the SB-24. All agreed that they are superior in design, quality and performance to what they are currently using so, hopefully, I've drummed up a little more business for you folks as a way of expressing my appreciation. Thanks again, Thomas Donley

    Best Diffuser I have ever owned

    Posted by Richard DenUyl Jr. on 30th Jun 2023

    Every diffuser I have purchased in the past has been made of plastic and breaks within a year. This one is top quality. It sinks right side up and it has a protector so the water line attachment does not get stressed and crack off. It also produces way more bubbles in my pond that other bands.

    Lots of bubbles, lots of surface agitation.

    Posted by James T. on 30th Jun 2023

    After a strong cold front hit during summer-like temperatures a couple of weeks ago, we experienced a rapid turnover that caused a major fish kill in our 1/8 acre pond. The aeration system needed a revamp, so we decided to try something different. I went with this diffuser, vs. the round rubber membrane type we used to have, as I was never completely satisfied with how it moved the water on the surface. Not only does this unit make a lot of bubbles, it moves the top of the water much more vigorously than the previous unit did. We have a couple of small coves that didn't see much movement before, now we are seeing waves make it all the way to their shores. The stainless steel base is very sturdy, and much less cumbersome to maneuver than a plastic box full of gravel. The design of the diffuser ring makes a thick column of small bubbles, along with good surface agitation. I am very pleased with this purchase.

    stainless steel wont harm fish

    Posted by Amazon Customer on 30th Jun 2023

    At first I wondered why they were so expensive. But being made out of stainless steel there won't be a reaction with the water and if you prize your fish like I do I don't want to harm them in any way. Do yourself a favor and keep any aluminum or iron or any other metals except stainless steel out of your ponds .
