Keep Your Pond Clean and Oxygenated With the ProLake 3.12 Aeration System
Is your pond turning murky, stagnant, or filling up with unwanted scum? Deeper water starved of oxygen quickly becomes a problem for your fish and everything living in it. This electric aeration system pushes oxygen through your entire water column on ponds and lakes up to 12 surface acres, keeping the water clear, healthy, and problem free all year round. With three custom-built compressors and a programmable timer found on no other system, you decide exactly when your water gets aerated.

Three Compressors Delivering Serious Air Volume

Power is what separates a working aeration system from a decorative one. This setup runs three ½ horsepower compressors, each capable of delivering 5.3 cubic feet of air per minute, that together push up to 15.9 cubic feet of air per minute down to the diffusers below.
-
Non-clogging, self-cleaning Duraplate™ diffusers that keep flowing without constant attention
- Diffusers rated to handle depths down to 50 feet
-
High volume cooling blowers and fully adjustable brushed aluminum manifolds for fine control
- Built for continuous 24/7 operation, day and night, even on cloudy days
Oxygen keeps fish and aquatic life alive and healthy while breaking the cycle of stagnation that feeds bacteria and surface scum.
The Only System With a Programmable Timer

Most aerators run on one setting: on. This one hands the schedule back to you. The UL Listed programmable timer lets pond and lake owners set exact aeration times to match their needs.
-
Seven-day, 24-hour control for a full weekly schedule
-
Power outage backup so your settings survive an interruption
-
Manual override whenever you want air on demand
-
Permanent schedule retention and a locking hasp for security
Note that the timer is included on the complete diffuser packages and is not part of the cabinet-only configuration.
Inside the ProLake 3 Cabinet

Everything is housed in a durable, sound-deadening cabinet measuring 40"W x 24"L x 24"T. Open it up and you will find every component built to last, not mass produced.
-
3/4 inch thick cabinet instead of thin plastic or thin metal
-
1" ASTM certified acoustical sound-deadening foam keeping operation quiet at just 50/60 decibels
-
Custom built compressors, a 3-4 port manifold for easy expansion, and a pressure gauge
-
Cooling fan to protect the components during round-the-clock running
The diffusers themselves are rugged enough to withstand 500+ lbs and feature shrouded, protected parts that keep debris and predators out.
Why the ProLake 3.12 Pond Aerator Is a Green Choice

Even a remotely located pond can stay clean and clear without harming the environment. Electric aeration is one of the safest, most eco-friendly ways to keep your water moving.
- Requires very little maintenance while running day and night
- Helps cut cost and save energy with an energy efficient design
- Keeps deeper ponds from going stagnant, protecting the quality of life for your aquatic life
Suited to HOAs, golf courses, recreational ponds and lakes, retention ponds, industrial retention ponds, farm ponds, ski parks, aquaculture ponds, and zoological displays.
Flexible Placement With the ProLake3 3.12 Aeration System

Your electrical hookup does not have to sit at the water's edge. Install the cabinet wherever power is convenient and route the air out to the water.
- Position the cabinet up to 4,000 feet away from the pond
- Run a 1/2 inch PVC line from the cabinet to a remote manifold
- From that remote manifold, run airlines out to the Duraplate™ diffusers
A Level-Aer™ equipment pad (30" x 30" x 3") is suggested for a stable base but is not included.
