High-Capacity Subsurface Aeration for Ponds & Lakes – These rocking piston aeration compressors deliver powerful, consistent airflow for deep-water bottom aeration, improving oxygen distribution and full pond turnover in depths up to 40 feet.
Reliable Rocking Piston Performance – Oil-free, sealed bearing design with vibration-isolating mounts ensures quiet, low-maintenance operation built for continuous or intermittent use. Ideal for long-term pond and lake aeration systems.
Improves Water Quality Year-Round – Increases oxygen levels, reduces thermal layering, helps break down fish waste, and allows harmful gases to safely escape. Also assists in preventing surface freeze-over during winter months.
Weather-Protected & System-Ready – Includes a weather-resistant ground-mounted cabinet with cooling fan, replaceable air filter, pressure relief valve, and isolation mounts. Designed to pair with subsurface diffusers; tubing and diffusers sold separately.

Bottom aeration circulates oxygen throughout your pond, breaks down waste, and releases harmful gases like methane and hydrogen sulfide. In ponds deeper than 6–7 feet, thermal layering traps oxygen-poor water at the bottom—aeration solves this by disrupting the thermocline.
Benefits: Healthier fish, improved water quality, prevents winter freeze-over, reduces debris buildup, and eliminates harmful turnover events.
PA-RP60P (1/2HP): Delivers up to 3.9 CFM. 120V, 3.5-amp motor, 6-ft cord. Ideal for depths up to 25 ft (max 40 ft). Flow: 3.9 CFM @ 5 PSI, 3.5 CFM @ 10 PSI, 3.0 CFM @ 15 PSI.
PA-RP80P (1HP): Delivers up to 6.7 CFM for larger ponds. 120V, 2.5-amp motor, 6-ft cord. Efficient to 25 ft (max 40 ft). Flow: 6.7 CFM @ 5 PSI, 6.3 CFM @ 10 PSI, 5.7 CFM @ 20 PSI.
Both feature oil-free design, sealed bearings, debris-trapping air filter, and vibration-isolating mounts for quiet, reliable operation.
Weather-Resistant Cabinet: Powder-coated steel enclosure with vented panels, integrated cooling fan to prevent overheating, and lock and key set. Mountable to ground or wall.
How to Use: Start slowly—run 1 hour/day, then increase by 1 hour daily (during daylight) until reaching continuous operation. This prevents shocking the ecosystem. For best results, pair with beneficial bacteria after a few weeks of consistent oxygenation.
