Description
The EasyPro PA86D Sentinel Deluxe is the most complete sub-surface diffused aeration kit in the PA86 series — the ¾ HP Stratus SRC75 Gen 2 rocking piston compressor, SC22 lockable steel cabinet, four QS2 diffuser assemblies, and 600 feet of 3/8" QuickSink weighted tubing are all included. Everything needed to aerate a pond up to 4 acres is in the box. Set the cabinet, run the tubing, place the diffusers, plug in, and turn on.
The SC22 steel cabinet arrives with the compressor, four-valve manifold, pressure gauge, pressure relief valve, cooling fan, and a pre-wired electrical outlet already mounted and plumbed. A 6-foot power cord pre-wired for a GFCI-protected outdoor outlet means no electrician is required for the cabinet connection. The Stratus SRC75 Gen 2 compressor is oil-less, designed for 24/7 continuous duty, and assembled in the USA. Operating cost is approximately $1.10 per 24 hours at $0.09/kWh.
Coverage Guide — Pond Size vs. Depth
The PA86D's four QS2 diffusers are calibrated for these coverage scenarios:
Rounder or more uniform pond shapes are more efficiently aerated than irregular or elongated ponds of the same acreage. Call us for sizing confirmation: (765) 508-4352.
Why Choose the EasyPro PA86D?
- Everything included — no separate purchases needed. The PA86D is the complete version: cabinet, compressor, manifold, pressure gauge, pressure relief valve, four QS2 diffusers, 600 feet of QuickSink tubing, all fittings and clamps. The PA86AD is the no-tubing version for custom installations.
- ¾ HP Stratus SRC75 Gen 2 rocking piston compressor. Oil-less design for 24/7 continuous operation without oil changes or lubrication. Assembled in the USA. Sound Shield acoustic insulation makes this one of the quietest rocking piston compressors in its class. 2-year warranty.
- SC22 lockable 14-gauge galvanized steel cabinet. Compressor, four-valve manifold, pressure gauge, and pressure relief valve arrive pre-installed. Integrated cooling fan prevents heat buildup and extends compressor life. Pre-wired 6-foot power cord for GFCI plug-in — no electrician needed for the cabinet connection. 5-year warranty.
- Four QS2 QuickSink dual-head rubber membrane diffusers (~1.6 CFM each, 6.5 CFM total). Self-weighted — no gravel bags or bricks required. Simply place on the pond floor. 5-year warranty.
- 600 feet of 3/8" QuickSink weighted tubing with fittings and clamps. Self-weighted tubing lies on the pond floor without additional anchoring. Sufficient for most standard installations reaching up to approximately 150 feet per diffuser run from the cabinet. 5-year warranty.
- Sub-surface diffusion for deep-water health. Diffusers placed at the pond floor circulate the entire water column, eliminating thermal stratification, oxygenating the muck layer, and venting bottom gases — tasks that surface fountains cannot accomplish in deep water.

Frequently Asked Questions
What pond size and depth is the PA86D rated for?
The PA86D is rated for ponds up to 4 acres, with coverage determined by 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 to a maximum depth of 50 feet. More uniform pond shapes (round, square) aerate more efficiently than irregular or elongated ponds. For complex or very large ponds, contact us at (765) 508-4352 for a free sizing consultation.
What is the difference between the PA86D and the PA86AD?
Both use the same ¾ HP Stratus SRC75 Gen 2 compressor, SC22 steel cabinet, four QS2 diffusers, and pre-wired power cord. The only difference is tubing:
- PA86D (this page): includes 600 feet of 3/8" QuickSink weighted tubing with fittings and clamps. Best for standard installations where 600' covers the distance from cabinet to all four diffusers.
- PA86AD: no tubing included. Best when you need custom lengths for an unusually large pond, complex layout, or when the cabinet must be placed far from the water.
For most residential and small commercial installations, the PA86D is the right choice — the 600 feet of tubing is sufficient to reach each diffuser with line to spare.
How much airflow does the PA86D provide, and is it enough?
The SRC75 compressor delivers 6.5 CFM at 4.5 amps — distributed equally across the four QS2 diffusers at approximately 1.6 CFM each. At that flow rate, each diffuser generates a vigorous rising bubble column capable of circulating the full water column above it.
For reference, EasyPro sizes this system for ponds up to 4 acres at appropriate depths. If your pond is larger or shallower than the coverage guidelines above, consider a dual-compressor system or a higher-HP unit. Call us for guidance.
What's pre-installed in the cabinet when it ships?
The SC22 cabinet ships with the following already mounted and plumbed:
- ¾ HP Stratus SRC75 Gen 2 rocking piston compressor
- Four-valve manifold outlet assembly
- Pressure gauge (allows you to monitor operating pressure and spot issues early)
- Pressure relief valve (safety feature — vents if system pressure exceeds safe operating range)
- Integrated cooling fan
- Electrical outlet with 6-foot pre-wired power cord for GFCI plug-in connection
Installation is: (1) place cabinet near pond, (2) plug into GFCI-protected outdoor outlet, (3) run QuickSink tubing to diffuser locations, (4) connect diffusers, (5) turn on. No electrician required for the standard 115V plug-in setup.
How does sub-surface diffused aeration compare to a floating fountain?
Sub-surface diffused aeration (PA86D) and floating fountains both add oxygen, but they address different problems:
- PA86D — sub-surface diffusion: Diffusers on the pond floor create rising bubble columns that circulate the entire water column. Directly addresses deep-water oxygen depletion, thermal stratification, bottom muck decomposition, and fish kill in deep ponds. No surface display. Most effective for ponds deeper than 6–8 feet.
- Floating fountain: Surface spray aerates the top 2–4 feet through splash and agitation. Adds visual appeal. Does not address deep-water stratification or bottom-layer oxygen depletion.
For a pond with both aesthetic and water quality goals, many property owners run a diffused aeration system for the health of the water and a decorative fountain for appearance. We can help size a combined approach — call (765) 508-4352.
Does the system run year-round including winter?
Yes, and year-round operation is recommended for most ponds. In winter, the rising warm water from each diffuser maintains an open hole in the ice directly above it, providing critical gas exchange that prevents oxygen depletion under ice cover — the leading cause of winter fish kills in northern climates.
The SC22 steel cabinet is rated for year-round outdoor operation. The cooling fan and galvanized steel construction protect the compressor through temperature extremes. Important note: in shallow ponds (under 6 feet average depth), consult EasyPro's guidelines before running winter aeration — circulating warmer bottom water to the surface can occasionally cause cold-water shock in very shallow, ice-covered ponds.
What maintenance does the PA86D require?
The SRC75 is designed for minimal maintenance:
- Air intake filter: Clean every 3–6 months (more often in dusty environments)
- Compressor rebuild kit (piston cups and gaskets): Replace every 2–3 years to maintain peak 6.5 CFM output — EasyPro rebuild kits are available
- QS2 diffuser membranes: Inspect annually; replace if rubber shows cracking or if airflow from that diffuser drops noticeably
- Pressure gauge: Monitor periodically for operating pressure within normal range
- GFCI outlet: Test monthly per standard practice
Compressor warranty: 2 years. Cabinet, diffusers, and tubing warranty: 5 years. With proper maintenance, these systems routinely operate beyond their warranty period.
Is 600 feet of tubing enough for my installation?
For most standard installations, yes. 600 feet of QuickSink tubing is sufficient for running lines from the cabinet to four diffusers placed in a typical pond. A common layout runs a single trunk line from the cabinet to a central distribution point, then branches to each diffuser. With four diffusers spread across a pond, 150 feet per run is usually adequate.
If your cabinet must be placed more than approximately 100 feet from the pond edge, or if your pond has an unusual layout that requires longer individual runs, you may need additional tubing. In that case, the PA86AD (no tubing included) allows you to purchase exact custom lengths, or you can add supplemental QuickSink tubing rolls to your PA86D order. Call us to plan your layout before ordering: (765) 508-4352.
