What is ID.me?
A 3/4 HP bottom-diffused aeration system that brings oxygen to ponds up to 4 acres and 50 feet deep — cleaner, clearer water in as little as 90 days.
The Airmax PS40 works from the bottom up, adding oxygen right where muck and organic debris settle. A shore-mounted compressor pushes air through multiple weighted diffusers on the pond floor, creating rising bubble columns that circulate the entire water column and prevent thermal stratification. With more dissolved oxygen and active natural bacteria, excess nutrients get metabolized instead of building up — leaving you with cleaner, clearer water and noticeably less muck, often within 90 days.
Coverage scales with pond depth — see the sizing table below to find your range.
Whisper-quiet 3/4 HP rocking piston compressor with SmartStart Technology for safe pressurized restarts.
Faux-rock composite cabinet blends into the landscape while protecting internal components — 10-year warranty.
Install at the water's edge or up to 1/4 mile away — no electrician required with Airmax EasySet airline.
Runs 24/7 for as little as $35.40 per month in electricity.
Most ponds show visibly cleaner, clearer water within the first three months of continuous operation.
The deeper your pond, the more surface area the PS40 can effectively aerate:

The heart of the system is a whisper-quiet 3/4 HP rocking piston compressor with rubber mounts for reduced noise and vibration. SmartStart Technology protects the compressor during pressurized restarts after a power interruption. Backed by a 3-year warranty.
An ETL-certified composite cabinet with a faux-rock finish blends into any landscape while protecting the compressor and electrical components. An elevated base guards against flood water, and a ventilation fan with rain shroud keeps things cool and dry. Backed by a 10-year warranty.
Airmax simplifies airflow management with dual 4-port manifolds featuring nickel-plated ball valves, braided hose sleeves that protect internal airlines from wear, and quick disconnects for fast, secure connections and easy removal for storage. Set up for either 3/8" or 5/8" airline — 5/8" is recommended if total airline length exceeds 600 ft.
High-efficiency membrane diffusers release fine oxygen bubbles into the water column without the maintenance headaches of traditional air stones. An integrated check valve prevents backpressure on the compressor, and the weighted sled keeps each diffuser upright and submerged during installation. Backed by a 5-year warranty.
If your PS40's compressor has failed, the genuine Airmax T75 (RP75) 3/4 HP replacement motor is a direct fit.
Shop PS40 Replacement Motor →How do I know which coverage I'll get from the PS40?
Coverage depends on your pond's depth: 6'-9' deep aerates up to 2 acres, 9'-12' deep up to 3 acres, and over 12' deep up to 4 acres.
Should I choose 3 or 4 diffusers?
More diffusers generally means better distribution across a larger or irregularly shaped pond. If you're unsure, call us and we'll help you size it based on your pond's dimensions.
Can the cabinet be installed far from the pond?
Yes — the compressor cabinet can sit at the water's edge or up to 1/4 mile away, connected by airline, so you're not limited to running power right to the shoreline.
Do I need an electrician to install this?
No special wiring is required at the pond itself — Airmax EasySet airline delivers oxygen to the water while the compressor plugs into a standard outlet at the cabinet location.
How long until I see results?
Most pond owners notice visibly cleaner, clearer water within about 90 days of continuous operation.
What's covered under warranty?
The ProAir diffusers and EasySet airline are covered for 5 years, the compressor and electrical components for 3 years, and the composite cabinet for 10 years.
My compressor stopped working — can I buy just that part?
Yes — the T75 (RP75) 3/4 HP replacement compressor is sold separately and is a direct fit for the PS40.
