Description
The EasyPro PA86AD Sentinel Deluxe is a complete sub-surface diffused aeration system for ponds up to 4 acres, built around the ¾ HP Stratus SRC75 Gen 2 rocking piston compressor delivering 6.5 CFM at 4.5 amps. Unlike surface or fountain aerators that only circulate the top layer of water, this sub-surface diffusion system places rubber membrane diffusers at the pond floor, creating rising columns of fine bubbles that circulate the entire water column from bottom to top — eliminating thermal stratification, introducing dissolved oxygen to deep water, and accelerating the aerobic decomposition of bottom muck.
The system arrives with the compressor, four-valve manifold, pressure gauge, and pressure relief valve already mounted inside the SC22 lockable steel cabinet with a cooling fan and a pre-wired electrical outlet. A 6-foot power cord is included for plug-in connection to a GFCI-protected outdoor outlet — no electrician required for the cabinet connection. Set the cabinet, run your tubing (purchased separately in custom lengths), install the four QS2 diffusers, and turn it on.
Coverage Guide — Pond Size vs. Depth
The PA86AD's effective coverage depends on both pond size and depth. Deeper ponds require less area coverage from a single diffuser because the rising bubble column creates more vertical circulation per diffuser. Shallower ponds require more diffusers per acre. The four QS2 diffusers in this system are appropriate for:
Pond shape also affects coverage — more uniform shapes (round or square) require fewer diffusers than irregular or elongated ponds of the same acreage. Call us for a free sizing recommendation at (765) 508-4352.
Why Choose the EasyPro PA86AD?
- Stratus SRC75 Gen 2 rocking piston compressor — oil-less design, specifically engineered for 24/7 continuous duty. Operating cost approximately $1.10 per 24 hours at $0.09/kWh. Assembled in the USA. 2-year warranty.
- Sub-surface diffusion vs. surface aeration — places oxygen at the bottom of the water column where stratification, muck decomposition, and fish kills originate. More effective for deep ponds than surface fountains or aerators.
- Sound Shield technology — Stratus SRC Gen 2 compressors feature EasyPro's Sound Shield acoustic insulation, making the PA86AD one of the quietest rocking piston systems in its class. Cabinet mounting adds additional noise dampening.
- SC22 lockable steel cabinet — compressor, four-valve manifold, pressure gauge, and pressure relief valve pre-installed. Integrated cooling fan extends compressor life. Pre-wired 6' power cord for plug-in installation. No exposed compressor to UV damage or weather.
- Four QS2 QuickSink dual-head diffusers — rubber membrane design, self-weighted, ~1.6 CFM each. No additional weights or anchoring needed. 5-year warranty.
- Custom tubing flexibility — because tubing is sold separately with the PA86AD, you purchase exactly the lengths you need for your specific pond layout. No waste, no undershooting.

Frequently Asked Questions
What pond size and depth is the EasyPro PA86AD rated for?
The PA86AD is rated for ponds up to 4 acres, with effective coverage depending on both pond size and depth:
- 1-acre pond: effective at 5–8 feet average depth
- 2-acre pond: effective at 8–12 feet average depth
- 4-acre pond: effective at 12–16 feet average depth
The system aerates down to a maximum depth of 50 feet. Pond shape also matters — round or square ponds are more efficiently aerated than irregular or elongated ones of the same acreage. For irregular or very large ponds, contact us for a sizing consultation.
Does the PA86AD include tubing?
No. The PA86AD does not include tubing. The "AD" suffix stands for Aerator + Diffusers — the system ships with the compressor cabinet, four QS2 diffuser assemblies, fittings, and clamps, but no airline tubing. This model exists specifically for installations where custom tubing lengths are needed.
You will need to purchase 3/8" QuickSink weighted tubing separately, in the lengths required to reach from your cabinet location to each diffuser placement. QuickSink tubing is self-weighted and lies on the pond floor without additional anchoring.
If you want tubing included, the PA86D is the same system bundled with 600 feet of QuickSink tubing.
How much airflow (CFM) does the PA86AD provide?
The ¾ HP Stratus SRC75 Gen 2 compressor delivers 6.5 CFM (cubic feet per minute) of airflow at 4.5 amps. This air is distributed through four QS2 dual-head diffusers, with approximately 1.6 CFM per diffuser. Each diffuser creates a rising column of fine bubbles from the pond floor that lifts and circulates the full water column, eliminating thermal stratification and venting stagnant bottom gases.
What is included in the Deluxe Sentinel Cabinet?
The SC22 lockable steel cabinet comes with the following pre-installed before shipping:
- ¾ HP Stratus SRC75 Gen 2 rocking piston compressor
- Four-valve manifold outlet assembly
- Pressure gauge
- Pressure relief valve
- Integrated cooling fan (extends compressor life by preventing heat buildup)
- Electrical outlet with a pre-wired 6-foot power cord for GFCI plug-in connection
No electrician is required for the cabinet connection — simply plug the 6-foot cord into a GFCI-protected outdoor outlet. The cabinet is lockable and ventilated for year-round outdoor operation. Cabinet warranty is 5 years.
What is the maintenance schedule for the SRC75 compressor?
The Stratus SRC75 Gen 2 is an oil-less rocking piston compressor designed for 24/7 continuous duty. Maintenance is straightforward:
- Air intake filter: Clean every 3–6 months depending on dust/debris in the installation environment
- Compressor repair kit (piston cups/diaphragm and gaskets): Replace every 2–3 years to maintain peak CFM output. EasyPro offers replacement kits for the SRC75
- QS2 diffuser membranes: Inspect annually; replace if membrane shows cracking or airflow is uneven
- Pressure gauge: Check periodically to confirm operating pressure is within normal range
The compressor carries a 2-year warranty; diffusers and cabinet carry 5-year warranties. With proper maintenance, these systems regularly operate well beyond their warranty period.
How does sub-surface aeration differ from a floating fountain?
Sub-surface diffused aeration (like the PA86AD) and floating decorative fountains both add oxygen to pond water, but they work differently and serve different priorities:
- Sub-surface aeration (PA86AD): Diffusers at the pond floor create rising bubble columns that circulate the entire water column. This directly addresses deep-water stratification, bottom muck decomposition, fish kill risk in deep ponds, and is the more effective aeration method for deep water bodies. No visual display on the water surface.
- Floating fountain: Motor and spray nozzle at the surface creates visual display and aerates the top 2–4 feet of the water column through splash and surface agitation. Excellent for visual appeal and surface aeration in shallower ponds, but does not address deep-water oxygen depletion.
For ponds deeper than 6–8 feet, sub-surface diffused aeration is generally the more effective choice for water quality. For shallow decorative ponds or HOA ponds where visual impact matters, a fountain may be sufficient or preferred. Many installations use both.
Can this system run year-round including winter?
Yes. Sub-surface aeration systems like the PA86AD can and should run year-round in most climates. In winter, the rising warm water from the pond bottom keeps a hole in the ice cover directly above each diffuser, providing gas exchange and preventing ice-induced fish kills. The SC22 cabinet is rated for year-round outdoor operation — the steel enclosure and cooling fan protect the compressor from temperature extremes.
Important: do not run the aeration system in shallow ponds (under 6 feet) during periods of extreme cold — circulating the warmer bottom water to the surface can cause winter fish kills in ice-covered shallow ponds. For ponds under 6 feet deep, consult EasyPro's sizing guidelines or contact us for guidance.
What tubing do I need to buy separately?
The PA86AD connections are set up for 3/8" inside diameter (ID) tubing. EasyPro's QuickSink weighted tubing in 3/8" ID is the recommended product — it is self-weighted and stays on the pond floor without additional anchoring. It carries a 5-year warranty.
To calculate how much tubing you need: measure the distance from the cabinet location to each diffuser's planned placement, then add 10–15% for routing and connections. Run a single line from the cabinet to the area of the pond, then branch to each of the four diffusers. Call us at (765) 508-4352 and we can help size your tubing order.
