Airmax LakeSeries LS120 Aeration System

Dual SilentAir Rocking Piston Compressors with Integrated SmartStart Technology (IST) – The heart and soul of the LS120 are 2 powerful whisper-quiet SilentAir 1 HP (2 HP System) Rocking Piston Compressors. Systems are built with Integrated SmartStart Technology to protect the compressor during pressurized restarts following power supply interruptions. Each highly efficient 230V compressor comes with rubber mounts to reduce noise and vibrations to ensure a silent operation. The LS120 can push up to 14.2 CFMs of oxygen to your pond while costing as little as $103.80 a month. Comes with a 3-year warranty.

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.

ProAir4 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 possess 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 diffuser plates 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.

Recommended usage can be year round. Summer to provide water movement, bind phosphates to the bottom of the pond, oxygen to the bottom of the pond for more fish capacity, take away their stress, prevent fish kills and promote beneficial pond bacteria (aerobic bacteria ) to the bottom of the pond to reduce muck and nutrients.

Winter use is to keep a hole in the ice for off gassing of toxic gasses. Keep the pond breathing so the fish don’t suffocate under the ice.
