PowerAir 4 Pond Aerator System

Breathe life into your pond with the PowerAir Bottom Diffused Aeration System. By increasing dissolved oxygen levels throughout all depths of water, you open up the entire pond to be inhabited by aquatic life.

Ponds need oxygen. All aquatic life in the pond need oxygen. Biological breakdown of nutrients and organic waste requires oxygen.

 PowerAir4 System Components:

  • 3/4 HP Rocking Piston Compressor
  • Compressor Cabinet with Cooling Fan
  • 4-Way Valve Assembly
  • 4 Weighted Dual Disc Diffuser Stations
  • 400' Weighted Rubber Airline
  • All Systems include a 2 year warranty

The PowerAir 4 Bottom Diffused Aeration System effectively aerates ponds 4+ acres in size.

The PowerAir Complete Aeration System Includes: 

The PowerAir Rocking Piston Compressor is built to operate continuously throughout the year. This compressor provides a low maintenance, low energy consumption, and low noise unit to meet all of your needs. 


The compressor is housed in a powder coated steel cabinet. This cabinet protects against 4 seasons of weather. Built in vents and cooling fan on the opposing side delivers ample air for operation. Good air circulation lowers the risk of a unit over-heating during warm weather. Access the compressor easily with the hinged lid. A locking arm is installed to prop the lid safely open during maintenance. Locking cabinet protects the system from tampering. The motor and cooling fan both plug in to the GFCI outlet, which is housed within the cabinet. For units with multiple diffusers- manifold control for airline is also housed within the cabinet.


Distribute dissolved oxygen to the entire body of water with our self-weighted diffuser stations. The self-sinking design makes installation a breeze. The diffuser base is powder coated to prevent rusting. A built-in check valve prevents the back-flow of water when system is shut down. The diffuser discs are constructed of a self cleaning rubber membrane. The rubber membrane contains hundreds of small slits which produces fine bubbles . All necessary pipe connections are included. Strain relief is included to avoid unnecessary stress on hose connections.

Pond Aerator-How to add oxygen to a pond

Times when aeration is a must- 

•Ponds with high nutrients
•Ponds covered in weed growth
•Extreme heat
•Prior to chemical application
•Sensitive fish species (trout)

Many reasons to aerate revolve around fish health. Algae blooms and pond weeds that overtake a pond can also diminish oxygen levels overnight. Pond owners are shocked when they see their fish belly up in the morning because nothing appeared to be wrong up to this point. Increasing water temperature also depletes oxygen. Similar to the issue with weeds consuming oxygen at night, this same oxygen consumption occurs as weeds die after chemical application. Although your chemicals are labeled as “safe for fish” this doesn’t take into account the natural process that is happening as the weeds die.  

Besides fish health, aeration provides additional benefits to the pond itself. Increased oxygen levels allow beneficial bacteria to thrive. Aeration is part of the proactive pond management process. Aeration improves water quality by aiding the break down of suspended organics in water.  

Pond Aerator Maintenance:

As with all aeration systems, we recommend replacing the air filter element every 3-6 months to protect the compressor against wear. 

Air Filter Replacement 

Every 2-3 years compressor maintenance kit can be utilized to improve motor performance/output
