Product Overview

Simply the finest diffuser on the market and WORKS WITH ANY BRAND OF COMPRESSOR.

Machined and crafted of Stainless Steel, EPDM Tubing and HDPE Plastic.

Massive 22" x 22" x 7" and weighs in at an impressive 13lbs, the DB-72 is designed to move a lot of water.

These units ship dissassembled and can be ready for your pond in about 5 minutes.

NO Membrane - NO Extra Backpressure!  The High-Efficiency Pond Aeration Diffusers from U.S. Solar Mounts are a step above the rest, utilizing Extruded EPDM Fine-Bubble tubing instead of industry-standard rubber membranes.

If moving and oxygenating extremely large volumes of water is what you need, this is THE diffuser for the job.  Perfect for large water bodies and Frac Water Normalization Tanks.

Compatible with Any Aeration Compressor that can deliver at least 2-2.5 CFM airflow to the pond bottom.

Each diffuser is ruggedly constructed using high-quality, American-Made components.  Assembly takes only about 5 Minutes, making installation quick & easy. Features like a custom-designed manifold assembly, dual-size hose strain relief, and a massive water flow rating set the DB72 apart from the competition.

Compatible with 3/8" or 1/2" ID Hose.

Ships with a 3/8" Hose Barb installed. A 1/2" Hose Barb can be added as an option - Simply change the barb fitting for 1/2" ID Hose. Can be easily adapted for other hose sizes as well.

LIFETIME WARRANTY included on all diffusers.

    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

    Great quality built product! Produces a lot of bubbles and moves the water as it should. We have bought both the DB-36 and the DB-72 Diffusers and are very happy with our purchases!

    This thing is AWESOME! I was skeptical, but this diffuser really moves a huge amount of water. Great design. Only complaint is I wish the cost was lower.
