Matala Hakko HK250L Linear Air Pump 12,000 Gallons

Powerful Aeration for Big Water With the Matala HK250L Air Pump

Struggling to keep a large pond or lake oxygenated? When your water spans 12,000 gallons or more, standard aerators simply cannot move enough air. This high volume pump pushes a massive column of bubbles from the bottom up, dragging oxygen depleted water to the surface where it bursts into turbulence, circulation, and fresh air. Rugged, reliable, and built to shrug off the weather, it keeps your water alive season after season.

Massive Air Lift for Ponds and Lakes Over 12,000 Gallons

Big water needs big airflow, and this pump delivers exactly that. Designed for ponds and lakes larger than 12,000 gallons, it creates a towering "air lift" of bubbles that rises straight from the bottom.

• Draws oxygen depleted water up from the depths
• Bursts bubbles at the surface for strong turbulence and circulation
• Boosts aeration across a wide area of water
• Handles depths of up to 10 ft

The result is healthier, better circulated water that supports fish and keeps stagnation in check.

Air Flow and Pressure Performance in the Hakko HK250L

This is one of the strongest pumps in the lineup, moving air at a maximum flow of 13.4 cfm (378 lpm) while drawing 227 watts. The performance curve plots air flow in lpm (0-400) and cfm (0-14) against pressure in psi and bar, with depth references in both feet and meters running along the top. Output starts near 375 lpm at zero pressure and tapers as depth and back pressure increase, with a rated pressure marked at 0.20 bar (2.85 psi), declining all the way to zero airflow near 6.40 psi.

• Max flow: 13.4 cfm / 378 lpm
• Power draw: 227 watts
• Noise level: 56 dB
• Recommended tubing size: 1"
• Tubing length: Less than 100 ft
