Description
Can-Air® MEGA Bottom Diffused Aeration System: Unmatched Efficiency for Ponds, Lakes, and Lagoons
Can-Air® MEGA Bottom Diffused Aeration Systems with Cabinet are designed for large ponds, lakes, dugouts and industrial lagoons that require substantial bottom-diffused circulation. Proudly designed and assembled in Canada, each system combines Can-Air® MEGA diffusers, sinking airline, dependable Can-Air® rocking piston compressors and protective compressor cabinets in one complete aeration package.
The MEGA is the largest diffuser in the Can-Air® lineup, providing up to 50% more diffuser area than many competing systems. Its large diffuser surface helps create strong circulation from the bottom of the water body, improving oxygen distribution and supporting effective mixing in large and deep-water applications.
The durable stainless steel MEGA diffuser base is self-weighted and designed to settle upright on the pond or lake bottom. Weighted sinking airline keeps the air delivery system below the surface, while the compressor and electrical equipment remain safely onshore inside the included protective cabinets.
With no floating equipment at the surface and no electrical components in the water, Can-Air® MEGA systems provide powerful bottom circulation without interfering with boating, swimming or the natural appearance of the water body. The MEGA system is intended for larger aeration applications and is recommended for ponds and lakes greater than approximately 2–3 acres.

System Size Guide
Choosing the Right MEGA Aeration System
The area one Can-Air® MEGA diffuser can service depends on water depth, climate and overall pond condition. Deeper diffuser placement generally creates a larger circulation pattern, while eutrophic or problem ponds require more intensive aeration coverage.
Approximate Area Covered by One Can-Air® MEGA Diffuser
| Pond Depth | Northern Climates | Southern Climates | ||
|---|---|---|---|---|
| Good Ponds / Preventative | Eutrophic / Problem Ponds | Good Ponds / Preventative | Eutrophic / Problem Ponds | |
| 5–8 ft | 80 ft x 80 ft | 55 ft x 55 ft | 90 ft x 90 ft | 75 ft x 75 ft |
| 9–12 ft | 155 ft x 155 ft | 105 ft x 105 ft | 180 ft x 180 ft | 150 ft x 150 ft |
| 13–15 ft | 200 ft x 200 ft | 155 ft x 155 ft | 230 ft x 230 ft | 190 ft x 190 ft |
| 16–20 ft | 260 ft x 260 ft | 190 ft x 190 ft | 290 ft x 290 ft | 240 ft x 240 ft |
| 20+ ft | 360 ft x 360 ft | 275 ft x 275 ft | 400 ft x 400 ft | 330 ft x 330 ft |
| 30+ ft | 400 ft x 400 ft | 330 ft x 330 ft | 445 ft x 445 ft | 370 ft x 370 ft |
These values serve as general aeration sizing guidance. Pond shape, depth profile, water quality and site conditions may affect the system required.
System Components
Choose Can-Air® MEGA 1 through MEGA 6 based on the number of diffusers required for your pond, lake or lagoon. Each configuration includes the appropriate protective compressor cabinet or cabinets.

Installation
Can-Air® MEGA systems are installed with the compressor equipment safely located onshore inside the included protective cabinets. Sinking airline runs from the compressor or manifold to each MEGA diffuser positioned on the pond, lake or lagoon bottom.
Systems with one, two or three MEGA diffusers use one compressor cabinet. Larger systems use two cabinets to accommodate the two-compressor configurations. Where appropriate, two cabinets may be mounted back-to-back.
If the water body contains fish and has not previously been aerated, begin with the diffuser positioned at approximately half the intended depth. Lower the diffuser approximately 2 ft every other week until it reaches the bottom. Gradual startup helps reduce the risk of rapidly mixing poor-quality bottom water and accumulated gases throughout the water column.

Frequently Asked Questions
What Is a Can-Air MEGA Aeration System?
The Can-Air® MEGA is a bottom-diffused aeration system designed for large ponds, lakes, dugouts and industrial lagoons. Air is delivered from an onshore compressor through sinking airline to MEGA diffusers positioned on the bottom.
What Is Different About the MEGA Diffuser?
The MEGA is the largest diffuser in the Can-Air® lineup and provides up to 50% more diffuser area than many competing systems. Its stainless steel base is self-weighted and designed to settle upright.
What Size Water Body Is the MEGA Designed For?
The MEGA system is intended for larger aeration applications and is generally recommended for ponds and lakes greater than approximately 2–3 acres. Actual system sizing depends on depth, shape, water quality and site conditions.
How Many Diffusers Are Available?
This listing includes configurations with one to six Can-Air® MEGA diffusers. Contact Pond Pro if your project requires a larger or custom aeration layout.
Does This System Include a Cabinet?
Yes. Every system on this page includes the appropriate protective compressor cabinet or cabinets for the compressor configuration supplied.
How Many Cabinets Are Included?
MEGA 1 through MEGA 3 include one compressor cabinet. MEGA 4, MEGA 5 and MEGA 6 include two cabinets because these configurations use two compressors.
Does Electrical Equipment Go in the Water?
No. The compressor and electrical equipment remain onshore inside the cabinets. Only the sinking airline, fittings and MEGA diffusers are installed in the water.
Does the Airline Sink?
Yes. The systems include weighted sinking airline designed to remain submerged below the water surface.
Can the MEGA System Be Used in Deep Water?
Yes. The MEGA sizing guide includes recommendations for diffuser placement at depths of 30 ft and greater. Final sizing should account for the water body's depth profile and overall conditions.
Can I Install the Diffuser Immediately at Full Depth?
If the pond or lake contains fish and has not previously been aerated, begin at approximately half depth and lower the diffuser approximately 2 ft every other week until it reaches the bottom.
Can the MEGA System Help Improve Water Quality?
Bottom aeration improves circulation and oxygen distribution throughout the water column. Can-Air® Aeration has also been proven to reduce phosphates by up to 95% in many applications.
What Voltage Are the Compressors?
Can-Air® compressors and associated cooling equipment are available in 120V or 240V configurations.
What Is the Warranty?
Can-Air® systems include a two-year standard warranty, extended to three years when purchased with a protective compressor cabinet. Because the systems on this page include protective compressor cabinets, they qualify for the three-year Can-Air® system warranty.
How Do I Know What Size System I Need?
Use the sizing guide above as a starting point. Pond shape, depth, water quality and site conditions can affect the system required. For project-specific recommendations, contact Pond Pro at sales@pondpro.ca.
