The SilentAir G33 (RP33 82R) 1/3 HP Maintenance Kit is designed to restore airflow and operating efficiency in dual rocking piston compressors used in pond and lake aeration systems. Over time, internal wear components naturally degrade, leading to reduced pressure and oxygen delivery.

This complete rebuild kit includes all essential replacement parts needed to return the compressor to proper working condition, helping extend system life and maintain reliable aeration performance.

Why Choose the SilentAir G33 Maintenance Kit?

  • Restores Airflow: Replaces worn pistons, valves, and seals that reduce oxygen output.
  • Complete Service Kit: Includes all critical internal components for a full rebuild.
  • Planned Maintenance: Designed for routine service every 12-18 months.
  • Wide Compatibility: Fits multiple PondSeries, LakeSeries, and legacy aeration systems.
  • Extends Compressor Life: Preventive maintenance reduces long-term wear and downtime.

  • Cylinder Sleeves: 2

  • O-Ring Gaskets: 2
  • Piston Cups: 2
  • Screws: 8 (4 Torx head not used)

PRO TIP
