The SilentAir G75 (RP75 72R) 3/4 HP Maintenance Kit is designed to restore proper airflow and operating efficiency in dual rocking piston compressors used in pond and lake aeration systems. Over time, internal wear components naturally degrade, reducing output and overall system performance.

This kit includes all critical internal parts needed to service both the newer G75 compressors and the earlier RP75 72R versions, allowing aeration systems to be returned to peak operating condition without replacing the compressor.

Why Choose the SilentAir G75 Maintenance Kit?

  • Restores Airflow: Replaces worn internal components that reduce pressure and oxygen delivery.
  • Complete Service Kit: Includes valve plates with pre-installed leaf valves and all required seals.
  • Broad Compatibility: Supports multiple compressor generations used in PondSeries and LakeSeries systems.
  • Planned Maintenance: Designed for routine service every 12-18 months.
  • Extends Compressor Life: Preventive maintenance helps avoid costly compressor replacement.
