The Kasco 2400AF 1/2 HP Surface Aerator is a high-efficiency, continuous-duty aeration unit for ponds up to 1/2 acre, capable of operating in water as shallow as 15 inches. It runs on 120V only — there is no 240V variant for this model — drawing 5.0 amps at full load. The unit ships with a UV-resistant float, two 50-foot braided nylon mooring ropes, and a sacrificial zinc anode. The bottom screen and C-25 control panel are optional accessories, not included standard. 1/2 HP — Up to 1/2-Acre Coverage 5.0A @ 120V — 120V Only (No 240V Version) 200 ft SJTOW Cord 15" Minimum Operating Depth 3.0 lbs O₂/HP/hr — Auburn Tested Float + 2×50' Mooring Ropes Included Zinc Anode — Salt & Freshwater Safe 2-Year Warranty | Made in USA Kasco 2400AF Bottom Screen & Control Panel — Optional What's Included — Kasco 2400AF Kasco 2400AF 1/2 HP surface aerator motor unit UV-resistant thermoplastic float assembly Two (2) 50' braided nylon mooring ropes Sacrificial zinc anode (corrosion protection) 200 ft SJTOW underwater-rated power cord Cable strain relief hardware Owner's manual and installation guide Bottom screen and C-25 control panel are NOT included — both are optional accessories. The bottom screen protects the propeller from debris and is strongly recommended for ponds with heavy leaf fall, algae mats, or string weed. The C-25 control panel adds a 24-hour timer, GFCI protection, and photocell for lighting. The 2400AF is 120V only — there is no C-85 or other 240V panel option. See Optional Accessories section below. Unlike Kasco's 3/4 HP and 1 HP aerators — which have 120V (AF) and 240V (HAF) versions — the 2400AF is available in 120V only. If you require a 240V 1/2 HP aerator, Kasco does not manufacture one. Consider the 3400HAF (3/4 HP, 240V, 3.4A) as an alternative if 240V service is the installation requirement. Aerators vs. Kasco fountains on mooring ropes: Kasco aerators include two 50-foot mooring ropes as standard. Kasco's decorative fountain models (2400JF, 3400JF, 4400JF) do NOT include mooring ropes — those must be purchased separately. If comparing the 2400AF aerator to the 2400JF fountain, rope inclusion is one of the meaningful differences.

Why the Kasco 2400AF? 3.0 lbs O₂/HP/hr — Auburn University validated. Auburn University's Standard Aeration Efficiency (SAE) testing confirmed Kasco aerators deliver at least 3.0 pounds of oxygen per horsepower per hour — the industry benchmark for comparing aeration systems. The 2400AF's single open propeller flings water droplets into the air and back into the pond, expelling dissolved methane, hydrogen sulfide, and CO₂ while absorbing atmospheric oxygen. For a 1/2-acre pond, the 1/2 HP matched to 1/2 acre is Kasco's standard recommendation: 1 HP per surface acre. 15-inch minimum operating depth — shallow-pond capable. The 2400AF's minimum depth is 15 inches — two and a half inches shallower than the 3400AF and 4400AF (17.5"). This makes the 2400AF the preferred choice for retention ponds, farm ponds with shallow-water zones, or any installation where the aerator may need to operate near a shallow shoreline. The 2400AF can follow the wind into shallower areas that would ground larger aerators. 120V only — simplest electrical installation in the Kasco AF series. The 2400AF plugs into a standard 120V GFCI outlet on a dedicated 15-amp circuit, drawing only 5.0 amps. No special wiring, no panel upgrade, no electrician required for most residential installations. The 3400AF (6.7A) and 4400AF (9.1A) may push homeowners toward circuit upgrades; the 2400AF comfortably fits a standard 15A circuit with 10A of headroom. Flood oil lubricated internal mechanical seal — built for 24/7 continuous duty. The motor uses a hard-face internal mechanical seal lubricated with flood oil for heat dissipation — the same design used across the entire Kasco AF series. This protects against shaft seal leaks under continuous operation and allows the stainless steel housing to dissipate motor heat through the water. Thermal overload protection shuts the motor down if temperatures exceed safe limits and restores operation automatically when cooled. Two 50-foot mooring ropes — deployment-ready out of the box. The 2400AF ships with two 50-foot braided nylon mooring lines. In most pond configurations, two ropes are sufficient to position the aerator in the optimal zone — typically the deepest or most stagnant area. A third rope can be added for windier installations or irregular pond shapes. Sacrificial zinc anode — salt and corrosive water protection. The zinc anode protects the motor housing from electrolytic corrosion, making the 2400AF suitable for brackish, coastal, and high-mineral-content water environments. Inspect annually; replace when the anode is reduced to less than half its original size. Replacement anodes are available from Kasco. Optional Accessories Available add-ons for the Kasco 2400AF (120V only) Bottom Screen — Protects the propeller from debris ingestion. Strongly recommended for ponds with heavy leaf fall, algae mats, or string algae that could foul the propeller. Note: swimmers should never be present when the aerator is running, with or without the screen. C-25 Control Panel (120V) — Adds a 24-hour mechanical timer, GFCI protection at the panel, and a photocell outlet for optional LED lighting control. The only applicable panel for the 2400AF (120V only — no C-85 option). LED Aerator Lighting Kit — Submersible LED lights compatible with the C-25 photocell outlet. Available in warm white, bright white, and color-changing configurations. Kasco Macrozyme Bacteria Treatment — Non-toxic beneficial bacteria and enzymes to reduce muck, neutralize odors, and improve water clarity alongside aeration. One 8-oz bag treats approximately 1/2 acre-foot of water — matched to the 2400AF's coverage area. Cord Protector Sleeve — Abrasion-resistant polyethylene sleeve to protect the 200 ft cord from wildlife, fish hooks, and weed trimmers along the shoreline run. Frequently Asked Questions What size pond is the 2400AF designed for? The Kasco 2400AF is designed for ponds and tanks with surface areas up to 1/2 acre. Kasco uses a standard rule of thumb of 1 HP per surface acre for the AF aerator series — making the 1/2 HP 2400AF the matched recommendation for 1/2-acre coverage. For ponds significantly larger than 1/2 acre, consider the 3400AF (3/4 HP, 3/4 acre) or 4400AF (1 HP, 1 acre). For heavy fish loads or chronic algae problems at 1/2 acre, upsizing to the 3400AF may produce better results than running a 2400AF at maximum capacity. Is this aerator available in 240V? No — the Kasco 2400AF is available in 120V only. Unlike the 3/4 HP and 1 HP models (which each have a 240V HAF variant), Kasco does not manufacture a 240V version of the 1/2 HP aerator. If your installation requires 240V service, the smallest available Kasco 240V aerator is the 3400HAF (3/4 HP, 240V, 3.4 amps). Call us to discuss sizing and voltage options: (765) 508-4352. Can the 2400AF operate in shallow water? Yes — the 2400AF has a minimum operating depth of 15 inches, making it the most shallow-capable unit in the Kasco AF aerator series (the 3400AF and 4400AF require 17.5"). This makes the 2400AF well-suited for retention ponds, farm ponds with variable depth, and installations where the aerator may drift toward shallow shoreline areas in wind. The float and mooring rope system keeps the unit properly positioned in most conditions. Is the bottom screen included? No — the bottom screen is an optional accessory, not included with the 2400AF. The bottom screen mounts below the float to prevent the open propeller from ingesting large debris. Kasco strongly recommends adding the screen for any pond with significant leaf fall, algae, or string weed. Note: the bottom screen does not make the aerator safe for swimmers — the propeller is a hazard regardless, and swimmers should never be present when the aerator is running. Call us to add the bottom screen: (765) 508-4352. Is a control panel included? No — the C-25 control panel is an optional accessory. The 2400AF plugs directly into a GFCI-protected 120V outlet without a panel. The C-25 adds a 24-hour mechanical timer (allowing scheduled operation rather than continuous run), GFCI protection at the panel, and a photocell outlet for LED lighting accessories. The C-25 is the only control panel option for the 2400AF — since there is no 240V version of this aerator, the C-85 and C-95 panels do not apply. Call us to add the C-25: (765) 508-4352. What are the electrical requirements? The 2400AF draws 5.0 amps at 120V and requires a dedicated 15-amp GFCI-protected circuit. The 200-ft cord is SJTOW-rated (suitable for continuous outdoor and underwater exposure) and should run without splices to the power source. Do not use an extension cord. At 5.0 amps on a 15-amp circuit, there is 10 amps of headroom — the 2400AF fits a standard residential 15-amp outdoor circuit without upgrade for most installations. How does this compare to the Kasco 3400AF (3/4 HP)? The key differences between the 2400AF and 3400AF are coverage, depth, voltage options, and amps. The 2400AF (1/2 HP, 5.0A, 120V only) covers ponds up to 1/2 acre and can operate in 15" of water. The 3400AF (3/4 HP, 6.7A, 120V) covers up to 3/4 acre and requires 17.5" minimum depth; its 240V sibling (3400HAF, 3.4A) is also available. For a 1/2-acre pond with normal fish loads and algae pressure, the 2400AF is appropriately sized. For ponds near 1/2 acre with heavy koi loads or severe algae, consider the 3400AF for extra capacity.
