The SilentAir G33 (RP33 71R) 1/3 HP Maintenance Kit is designed to restore proper airflow and efficiency in older dual rocking piston compressors used in legacy aeration systems. As internal wear components age, airflow output and system performance naturally decline.

This maintenance kit includes all essential replacement parts needed to service the compressor and return it to reliable operating condition. Regular maintenance helps extend compressor life and maintain consistent oxygen delivery in ponds and lakes.

Why Choose the SilentAir G33 Maintenance Kit?

  • Restores Performance: Replaces worn internal components that reduce airflow and pressure.
  • Designed for Older Systems: Built specifically for pre-2011 aeration models.
  • Planned Maintenance: Recommended service every 12-18 months.
  • Cost-Effective Repair: Extends compressor life without full replacement.
  • Reliable Operation: Helps maintain steady aeration in established pond systems.

PRO TIP

When servicing legacy compressors, take note of part orientation during disassembly. Correct reassembly is essential for balanced piston operation and long-term reliability.
