A commercial-grade fine-bubble aeration diffuser built with a weighted stainless steel base, high-flow EPDM diffuser tubing, integrated check valve, and very low backpressure. The DB-36 is designed to improve oxygen transfer and circulation while reducing unnecessary compressor restriction in pond and lake aeration systems.
Product Overview
The DB-36 High-Efficiency Diffuser is a premium fine-bubble pond and lake aeration diffuser engineered for performance, durability, and long underwater service life. It combines a weighted stainless steel base, stainless steel hardware, high-flow EPDM diffuser tubing, an integrated check valve, and flexible airline connection options in one rebuildable assembly.
Because the diffuser is the final delivery point in an aeration system, its design directly affects bubble quality, water movement, oxygen transfer, and compressor loading. The DB-36 produces uniform fine bubbles around the diffuser loop while maintaining very low backpressure, helping more of the compressor's output create useful circulation instead of being lost to restriction.
Key Benefits
High-Efficiency Fine-Bubble Tubing
Instead of a fragile disc-style membrane, the DB-36 uses high-flow EPDM aeration tubing that releases fine bubbles along the entire loop. Fine bubbles provide greater air-to-water contact than larger bubbles, supporting efficient oxygen transfer and strong vertical circulation. The low-resistance tubing also helps compressors operate against less restriction.
The DB-36 is a strong replacement option for older disc membrane diffusers and lower-quality plastic diffusers that may clog, harden, crack, burst, or require frequent replacement.
All-Stainless Base for Stable Placement
The weighted stainless steel base and stainless mounting hardware provide corrosion resistance, stable placement, and long-term durability on the pond or lake bottom. The rigid base is designed to land upright and helps protect the airline connection from unnecessary movement and stress.
Included Equipment
Technical Specifications
Compatibility and Installation
The DB-36 can be used as a replacement diffuser or as part of a new pond or lake aeration system. It is compatible with many compressors capable of supplying approximately 1 CFM or more, but actual diffuser performance depends on compressor output at pressure, pond depth, airline diameter, airline length, fittings, and overall system layout.
The compressor must be capable of delivering adequate airflow at the installed depth after accounting for hydrostatic pressure and friction loss. Proper system sizing is essential for efficient operation and compressor life.
Typical Applications
Warranty Summary
The DB-36 is covered by a limited lifetime warranty for parts, materials, and workmanship, subject to the current U.S. Solar Mounts Corp Limited Product Warranty and any applicable product-specific terms. The warranty does not cover physical damage, misuse, abuse, cleaning, or routine maintenance. A defective part may need to be returned for replacement.
