Pond & Lake Aeration & Aquatic Products

AirLift 4

Hydro Logic Products® AirLift 4™ pond aeration systems are designed and built to cost effectively mix and aerate ponds and lakes. Our systems use billions of micron sized bubbles to improve pond and lake water quality. Our AirLift 4™ aeration system can aerate ponds and lakes up to 8-acres in size depending on air diffuser placement, nutrient concentrations, biological oxygen demand (BOD), water depth and other physical characteristics of the waterbody.

Reduce High Metal Concentrations
Reduce Nutrient Releases by Anoxic Sediments
Reduce Buildup of Poisonous Gases
Reduce Release of Noxious Odors
Reduce the Accumulation of Sediments
May Reduce Nuisance Levels of Aquatic Plants
No Electricity in the Water
Warranties on all System Components

Product Description

Our AirLift 4™ aeration system is powered by a 1/2 H.P. energy efficient, dual piston air compressor equipped with our proprietary SureStart™ technology. Our dual piston air compressor, which can deliver air under high pressures (water depths up to 50 feet), operate very quietly (55 decibels at 2 meters/6 feet). In comparison, the noise levels of our air compressors are about 15 decibels less than equivalent rotary vane air compressors.

Our AirLift 4™ aeration system contains four (4) AirPod™ air diffusers. Each AirPod™ contains a self-cleaning 20-inch tube, EPDM flexible membrane air diffuser equipped with a triple check valve system. Our air diffuser is constructed to withstand total airflow from the compressor without damaging the EPDM membrane (unlike EPDM disc air diffusers). The base of the AirPod™ provides a large surface area between the EPDM membrane and the sediments, thereby preventing sediment disturbance during system operation. The AirPod™ is extremely easy to install. Simply fill the two ballast tubes with pea gravel or sand prior to their placement in the pond or lake.

Compressed air from our dual piston compressor is delivered to the AirPod™ using our DownUnder™ self-weighted tubing. DownUnder™ air supply tubing is constructed of a flexible PVC composite and is kink proof and puncture resistant. Our easy to install tubing comes in several different lengths and diameters to meet your installation needs.

Easy field repairs – plumbing connections with push-on style fittings & flexible 100 psi tubing
Noise reduction – mounted on cylindrical vibration pads & connected with flexible tubing
Extremely quiet operation (55 decibels @ 2 meters or 6 feet @ 20 psi)
Two-year warranty (best in the industry)

Description

Our dual piston air compressor (240 volt option available) is outfitted with our proprietary SureStart™ technology. This allows automatic restart of the air compressor under full pressure during any power outage (blackouts or brownouts) without damaging the air compressor motor. The air compressor is oil-less, thermally protected and requires no lubrication. The air compressors include rotors/stators manufactured with the most advanced magnetic materials, sealed heavy-duty precision bearings and starting capacitor. The only required routine maintenance is periodically changing the 5-micron air filters. The compressor can typically operate approximately 3 years or more before any decline in performance is observed. This is 2 to 3 times better performance over standard diaphragm and rotary vane compressors. Thereafter, the air compressor can be easily serviced by replacing the piston seals. Airflow versus pressure performance curves for our dual piston compressor vary less than for diaphragm and rotary vane compressors. This simply means that means that dual piston compressor provides more air while using less energy. Lastly, our dual piston air compressor can operate under high pressures, thereby allowing the air diffuser membranes to be easily cleaned without pulling the AirPod from the pond.

Diffuser Features

Four (4) AirPods each equipped with a single flexible, fine pore EPDM rubber membrane tube diffuser
More durable than air stone, porous media & EPDM disc diffusers
Produces extremely fine air bubbles (500 – 1,000 micron or 0.020 – 0.040 inch)
Triple check valve prevents water & sediment from entering the air supply lines
One EPDM tube diffuser is 20% larger than two 9-inch EPDM disc diffusers
Self-cleaning & very low maintenance

Description

Each AirPod™ air diffuser contains a self-cleaning 20-inch, EPDM flexible membrane tube diffuser equipped with a triple check valve system. The triple check valves prevent water and sediment from flowing back into the air supply lines during system shut down. The EPDM tube air diffuser is mounted to heavy-duty strut with ratcheting tie-downs to provide easy assembly/disassembly. The above components are secured to a large HDPE base. Two hollow ballast tubes are anchored beneath the base. The ballasts tubes are designed so that pea gravel or sand can be easily added to these tubes during installation.

Description

DownUnder™ air supply tubing is constructed of a flexible PVC composite and is self-weighted in order to firmly remain along the pond or lake bottom after the installation. Sections of DownUnder™ tubing are connected together using standard PVC solvent weld cement and ½ inch insert fittings. DownUnder™ air supply tubing has low friction walls for maximizing airflow rates and minimizing air pressure drops. Our DownUnder™ tubing is designed to reduce the overall system pressure requirements and to extend the life of the air compressors. The wall thickness provides long-term durability and protection against kinking and punctures. The air supply tubing remains flexible in cold temperatures allowing for easy year round installations.
