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.

    Very nice diffuser

    Posted by gornr on 1st Feb 2021

    The product has a robust design and build quality (stainless). I'm limited to 6' depth for diffuser operation in my pond due to the spec limits of the air compressor I'm using. The diffuser can be located in much deeper water. I bought two of the diffusers to increase the amount of dissolved oxygen added to the water due to significant muck build-up after about 35 years. Mr. Pipkin provided excellent support and was responsive to my questions regarding operation and installation.

    Lots of bubbles, lots of surface agitation

    Posted by James T on 1st Feb 2021

    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.

    Excellent product, Excellent service

    Posted by Steve on 17th Sep 2020

    I ordered four of the DB-36 diffusers. The product is rock solid and they really move the water. They came well-packaged and without any damage. The customer service from Eric was outstanding. The diffusers are very well made. Will definitely be doing business with US Solar Mounts again.

    Best Diffuser on the market!

    Posted by Jon M on 29th Jun 2020

    My wife and I have a 2.5-Acre pond. We originally purchased an aerator package online that included diffusers with plastic bases that we had to fill with pea-gravel to sink them. After a few years, the plastic fittings failed and we needed replacements. We purchased several of these diffusers from US Solar and could not possibly be any happier. The company was great to deal with and talked with us before the purchase. The diffusers are really, really well-built. The main assembly is ALL STAINLESS STEEL and is actually welded together! They move a noticeably higher volume of water compared to the disc-type that we used to have. Our compressor seems to run easier as well. Great Product! Would highly recommend this company!

    GREAT DIFFUSER - Very Well-Built

    Posted by Thomas H. on 1st Apr 2020

    Ive installed a lot of diffusers for customers (and my own). This is hand-down, by far the best-built diffuser on the market today from any company. We have installed a few of these units so far and they work great at various depths and different air flow settings. No plastic parts like many of the others out there. We did have to change the barb fitting since we use a lot of 1/2 air hose.
