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.

    Awesome!

    Posted by Brian S. on 10th Feb 2025

    This product is great, I'm ordering another one to put on the opposite end of my pond. Craftsmanship is great and it's so easy to assemble and install. Plus it's made in the USA.

    Aeriation

    Posted by BJ on 10th Feb 2025

    Used three of these for a large pond aeriation system. After 2 months, they are still putting out lots of air. I like the hose restraint & metal base. If the top circular diffuser can be replaced or rebuilt over the years, it is a good product.

    Best Diffuser I have ever owned

    Posted by Richard DenUyl Jr. on 10th Feb 2025

    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.

    Stellar Product

    Posted by Paddles and Props on 10th Feb 2025

    We've had this unit in our pond now for 2 years and it runs daily and has worked flawlessly. No maintenance required and the same air output today as two years ago. We've had other diffusers from other companies and this is hands down the best design and value that we've used. Don't chop anywhere else snag this one.

    Quick delivery. Wouid have liked a little bit bigger one but that's on me for not reading the dimensions. Is working great. Time will tell if it should be a 5* rating or not.

    Very Well Made!

    Posted by Invar69 on 10th Feb 2025

    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.
