Overview

Airmax LakeSeries Aeration Systems are engineered to be the best. Our aeration systems provide maximum aeration and circulation to lakes and large ponds. Aeration utilizes a shore-mounted air pump to deliver air to specialized diffusers that are located on the pond bottom.
The resulting column of rising bubbles circulates oxygen-rich water, eliminating stratification and improving the overall condition of your pond or lake.
With increased oxygen and circulation, excess nutrients in the pond or lake are metabolized, resulting in cleaner, clearer water and less muck. Results you can see in just 90 days!
Airmax PondSeries Aeration Systems are manufactured in the USA with high performance, professional quality components.
Looking to get even faster results? Combine aeration with all-natural water treatments such as beneficial bacteria.

Airmax LakeSeries LS120 Aeration System
Dual SilentAir
Lockable Powder-Coated Aluminum Cabinet - ETL electrical safety certified aluminum cabinet has a durable, secure design for long-lasting equipment protection. For increased security, cabinets feature a tamper-proof, integrated locking lid. Keeping the system running clean and cool is improved filtration and cooling technology, including dual cooling fans which provide maximum volumetric air exchange. An elevated base protects against damaging flood water. Cabinet dimensions: 30.25"L x 28.75"W x 21"H. Comes with a 10-year warranty.
ProAir®4 Weighted Diffusers - Designed for maximum oxygen uptake, up to 12 ProAir 4 Weighted Diffusers incorporate high-efficiency low-maintenance membrane sticks to release tiny oxygen bubbles into the water column. Membrane diffusers have the synergy of air stones without the headaches of cracking and acid-washing. The ProAir 4 Weighted Diffuser has an integrated check valve to prevent back-pressure on the compressor. The innovative sled design keeps the ProAir 4 submerged while maintaining an upright position during installation. Comes with a 5-year warranty.
Airflow Manifold Assembly - Airmax simplifies airflow management to individual diffusers with (2) 6-port manifolds with nickel-plated ball valves, as well as integrated pressure gauge and pressure relief valve. Additionally, airflow manifolds feature a quick-change fitting, for simplified maintenance and seasonal storage, if your system does not run year-round. The LakeSeries LS120 System is set up for 5/8" airline (Airline Sold Separately). The airline comes with a 5-year warranty.
Easy Installation with Options - Airmax Aeration Systems are the easiest and most versatile systems to install on the market. LakeSeries LS120 Systems can be installed at the water's edge or up to 1/4 mile away from the pond or lake. No power is needed at the shore. Airmax EasySet™ airline delivers oxygen to the water without the added expense of hiring an electrician. All Airmax LakeSeries Aeration Systems come with a pre-mounted composite base, which creates a flat stable surface for easy installation.

Piston Compressor
Highly efficient rocking piston compressors and manifolds with ball valves simplifies airflow management and continuous performance to individual diffusers.

Durable Aluminum Cabinet
ETL electrical safety certified powder-coated aluminum cabinet features a tamper-proof design for long-lasting equipment protection and security.

Diffusers
ProAir 4 Weighted Diffusers have an innovative maintenance-free sled design that keeps them submerged in water while maintaining an upright position during installation. Customizable from 6 to 12 diffusers.

Outside air is drawn up and into the cabinet by dual cooling fans. Clean, cool air then flows from the dual cooling fans, over the compressors, and through the cabinet, maximizing volumetric air exchange.

Air travels through an extra-large, integrated filter and a compressor air filter, maximizing the performance and longevity of the system, by protecting the compressors from outside contaminants.

Relief Valve
Each compressor includes a pressure gauge to help monitor system performance and a pressure relief valve to protect against backpressure.

Airline
Extend your aeration system's reach with EasySet Airline. 5/8" direct burial airline is perfect for underground applications. 5/8" self-weighted airline sinks to the bottom of the pond and is puncture-resistant for years of continuous use.

Connector Kits
A must-have for aeration installations. EasySet Airline Connector Kits include 5/8" barbed fittings and 2 stainless-steel hose clamps to connect two different lengths of self-weighted or direct burial airline securely in place.
