HC280D-1 Pond Aerator Pump | 340W 24V DC, 1-Acre Coverage

A shrimp farmer facing devastating stock losses because stratified water layers leave the bottom zone with zero oxygen knows the harsh reality of poor water management. When warm surface water traps cold, oxygen-depleted water at the bottom, toxic gases like ammonia and hydrogen sulfide accumulate rapidly. Benthic species suffocate, and organic waste piles up, creating a highly hazardous environment. For remote agricultural sites and off-grid aquaculture facilities, finding a reliable solution without access to grid electricity adds another layer of difficulty. The HC280D-1 addresses these specific challenges by providing continuous, deep-water circulation powered entirely by solar-compatible direct current technology.

Why Choose the HC280D-1

• Off-Grid Solar Compatibility: Operates on a highly efficient 24V DC motor drawing just 14.5 amps and ≤340W, making it perfect for pairing with 12V/24V solar panel arrays in remote locations.
• 1-Acre Coverage Area: Specifically engineered to turn over and oxygenate water volumes for ponds and lakes up to one full acre in size.
• Deep Water Operation: Generates enough pressure to push air to diffusers placed at maximum depths of 65 feet, reaching the lowest points of your reservoir.
• Dual Diffuser System: Includes 2 EPDM rubber membrane diffusers that distribute millions of micro-bubbles for maximum oxygen transfer efficiency.
• Thermal Protection: Built-in safety mechanisms shut down the compressor if temperatures reach 145±5℃, ensuring long-term durability in demanding outdoor environments.

How Bottom Aeration Works

Compressed air travels from the shore-mounted compressor through weighted tubing down to the EPDM diffusers resting on the pond floor. As air forces its way through the rubber membranes, it creates a massive column of upward-moving micro-bubbles. This constant upward flow pulls dense, oxygen-starved water from the bottom and brings it to the surface, effectively breaking the thermocline and mixing the entire water column. At the surface, harmful gases like ammonia are vented into the atmosphere, while the newly circulated water absorbs atmospheric oxygen. Meanwhile, the oxygenated water returning to the bottom stimulates beneficial aerobic bacteria, which rapidly digest accumulated organic muck and prevent foul odors from developing.

Ideal Applications for the HC280D-1

This specific 24V DC system is engineered for locations where traditional grid power is unavailable or too expensive to run. It is an excellent choice for 1-acre remote fish farms, particularly for bottom-dwelling species like shrimp or catfish that require pristine benthic conditions. Off-grid agricultural irrigation reservoirs, remote recreational fishing ponds, and golf course water hazards can all benefit from this solar-ready compressor. Because it handles depths up to 65 feet, it is highly effective in deep, steep-sided quarry ponds that are prone to severe stratification. During winter months, running this compressor continuously keeps a hole open in the surface ice, allowing toxic gases to escape and preventing winter fish kills in colder climates.

Frequently Asked Questions

Q: Can I connect the HC280D-1 directly to a standard AC wall outlet?

A: No, this is strictly a DC24V compressor designed for off-grid use. To run it from a standard 110V or 220V AC power source, you would need a high-capacity AC-to-DC power converter capable of handling the 14.5 A current draw. It is primarily intended to be wired directly to a 24V solar charge controller and battery bank.

Q: How far apart should I place the 2 diffusers in my 1-acre pond?

A: To achieve optimal water turnover, space the two diffusers evenly across the deepest sections of your pond. If your pond is roughly circular or square, placing them equidistant from the center will create two distinct lifting columns that overlap at the surface, ensuring the entire 1-acre volume receives adequate circulation.

Q: What type of tubing is required to reach the maximum depth of 65 feet?

A: You must use self-weighted aeration tubing to connect the compressor to the diffusers. Weighted tubing is essential because it sinks directly to the pond floor and remains out of sight, preventing entanglement with fishing lines or boat motors. Standard vinyl tubing will float and kink under the pressure required to reach depths of 65 feet.
