The SilentAir G25 (RP25 74R) 1/4 HP Maintenance Kit is designed to restore proper airflow and performance in single rocking piston compressors used in older pond aeration systems. As internal wear components age, airflow output gradually declines, reducing overall system efficiency.

This replacement kit includes all essential internal parts required to service the compressor and return it to reliable operation. Routine maintenance helps extend compressor life and maintain consistent oxygen delivery to the pond.

Why Choose the SilentAir G25 Maintenance Kit?

  • Restores Performance: Replaces worn pistons, valves, and seals that reduce airflow.
  • Designed for Legacy Systems: Built specifically for AM30 and pre-2016 PS10 aeration systems.
  • Planned Maintenance: Recommended service every 12-18 months.
  • Cost-Effective Repair: Extends compressor life without replacing the entire unit.
  • Reliable Operation: Helps maintain steady aeration and oxygen delivery.

PRO TIP

When servicing older compressors, inspect the cylinder and gasket surfaces carefully for residue or wear. A clean, smooth sealing surface helps ensure proper compression and long-term airflow performance.
