The Airmax SilentAir aeration compressor systems are designed to deliver reliable, continuous airflow for pond aeration using bottom diffusers. Built around efficient rocking piston or linear diaphragm technology, these compressors provide the pressure needed to move oxygen to the deepest areas of a pond while operating quietly and consistently.
Each system includes an integrated plate regulator and manifold with individual ball valves, allowing precise airflow control to each diffuser line. This makes it easier to balance oxygen delivery based on pond depth, diffuser count, and layout, whether the application is a decorative pond or a larger managed water body.
Why Choose SilentAir Aeration Compressors?
-
SmartStart Protection: Rocking piston models use SmartStart Technology to protect the compressor during pressurized restarts after power interruptions.
-
Quiet Operation: Rubber isolation mounts reduce vibration and operating noise.
-
Consistent Pressure: Rocking piston design maintains airflow even at greater depths.
-
Flow Control: Integrated manifolds and plate regulators simplify balancing air to multiple diffusers.
-
Energy Efficient: Designed to deliver strong airflow with controlled operating costs.
-
Serviceable Design: Maintenance intervals are clearly defined based on operating pressure.
Model Comparison and Typical Use
-
PS10 (1/4 HP): Produces up to 2.3 CFM. Best suited for small to mid-size ponds with moderate depth where quiet operation and low operating cost are priorities.
-
PS20 (1/2 HP): Produces up to 4.7 CFM. A good choice for medium ponds requiring multiple diffusers or slightly deeper water.
-
PS40 (3/4 HP): Produces up to 5.6 CFM. Designed for larger ponds or systems with several diffusers where higher pressure is needed.
-
PS60 (1 HP): Produces up to 7.1 CFM. Ideal for large or deeper ponds with multiple diffuser zones and higher oxygen demand.
-
SW20: Linear diaphragm compressor producing up to 2.5 CFM. Best for shallow ponds where lower pressure is required and ultra-low power consumption is preferred.
-
SW40: Linear diaphragm compressor producing up to 4.9 CFM. Suitable for shallow, wide ponds with multiple diffuser points but limited depth.
-
LS40 and LS60: Dual rocking piston systems designed for larger layouts where redundancy, higher airflow, or expanded diffuser coverage is required.
Maintenance Guidance
- 1-7 PSI average operating pressure: service every 18 months
- 8-12 PSI average operating pressure: service every 12 months
- 13-15 PSI average operating pressure: service every 9 months
- 16+ PSI average operating pressure: service every 6 months
PRO TIP
Select compressor size based on pond depth and diffuser count, not just pond surface area. Deeper ponds and long airline runs increase pressure demand, which is where rocking piston compressors outperform diaphragm-style units.
