Airmax EcoSeries 1/2 HP Pond Fountain
The 1/2 HP Fountain That Outperforms 3/4 and 1 HP Motors
The Airmax EcoSeries is a 1/2 HP floating pond fountain engineered around a stainless steel water-cooled asynchronous motor, silicon carbide shaft bearing, and ceramic shaft. It moves 225 gallons per minute without a nozzle and 130 GPM through one - out-throwing most 3/4 HP and 1 HP fountains while pulling only 5.8 amps at 115 V. That efficiency shows up on your electric bill: at eight hours a day, you'll spend around 53 cents.
Three spray patterns ship in the box - Classic, Crown & Trumpet, and Trumpet - and every nozzle swaps by hand in under a minute (no tools). Optional premium nozzles are available (Single Arch, Double Arch, Double Arch w/ Geyser, and Blossom) if you want a wider display or a taller geyser. Every kit ships with the 34-inch float, three included nozzles, and Airmax's 115 V Plug & Play control panel with two digital timers that let you run the fountain and an optional light set on separate schedules.
Configure cord length from 100 ft up to 400 ft, and pick standard, PolyFlex-protected, or stainless-steel-armored cord for exposed shorelines. Order the kit with the built-in control panel or opt out if you already have compatible switchgear. Backed by a 3-year Airmax warranty on both the fountain and control panel. Free shipping on every configuration.

Why Choose the EcoSeries
Requirements & What to Know Before You Buy
- Pond Size: aerates ponds up to 1/4 acre and 6 ft deep. Larger ponds will need additional diffused aeration or multiple fountains for full circulation.
- Minimum Operating Depth: 24 inches. The intake pulls water below the float; less than 24 in and the motor draws air.
- Electrical: standard 115 V household circuit, 5.8 amps running. The Plug & Play control panel plugs directly into a 115 V outlet with a 24-inch power whip - no dedicated 230 V circuit required.
- Cord Sizing: measure from the fountain's intended location straight to the shore outlet or panel location. Pick the shortest cord that reaches - excess cord in coils is a nuisance and can nominally derate voltage.
- Cord Protection - Standard: SJTOOW outdoor rubber jacket. Best for buried conduit runs and protected shorelines.
- Cord Protection - PolyFlex: braided sleeve over the SJTOOW cord. Rated for rocky shorelines, rodent-exposed installs, and dock traffic where a bare cord would take physical damage.
- Cord Protection - Stainless Steel Armored: stainless steel braid over the cord. Best for public installs and vandalism-prone sites.
- Quick Disconnect: 200 ft and longer cords include an underwater quick disconnect at the motor for easy seasonal removal and cleaning. Shorter cords do not include the quick disc by default.
- Mooring: supply anchors and rope separately. Airmax sells a compatible Fountain Mooring Kit in 150', 250', and 500' lengths (sold separately).
- Sizing Help: Call (470) 354-1969 with your pond dimensions and shore layout - we will confirm the right cord length and protection option.
