AirLift 4 HF

Product Description

Our AirLift 4 HighFlow™ aeration system is powered by two (2) 1 H.P. energy efficient, dual piston air compressors equipped with our proprietary SureStart™ technology. Our dual piston air compressors, which can deliver air under high pressures (water depths over 50 feet), operate very quietly (55 decibels at 2 meters or 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 HighFlow™ 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 diffusers are constructed to withstand total airflow from the compressor without damaging the EPDM membranes (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 AirPods are 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 AirPods™ 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.

Compressor Features

• Two (2) 1 HP dual piston air compressors with integral thermal motor overload protection
• Produce high airflow volumes (15 cfm combined) & operate under high pressures (45 psi max.)
• Oil-less air compressors that are virtually maintenance free
• SureStart™ technology allows air compressors to restart under pressure after power outages
• High air pressure allows diffusers to be cleaned in ponds or lakes (unlike rotary vane compressors)
• U.L. listed 240 volt (8.2 amps combined) under full load
• 5-micron air filters maximize air compressor life expectancy
  
• Easy field repairs – plumbing connections with push-on style fittings & flexible 100 psi tubing
• Noise reduction – mounted on cylindrical vibration pads & connected to flexible tubing
• Extremely quiet operation (55 decibels @ 2 meters or 6 feet @ 20 psi)
• Two-year warranty (best in the industry)

Description

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

Diffuser Features

• Four (4) AirPods each equipped with 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
• Large HDPE base (20”L x 15”W) to prevent sediment disturbance
• All AirPod components are corrosion resistant using PVC, fiberglass & HDPE materials
• Five-year warranty (best in the industry)

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.

Tubing Features

• Over-sized 0.58 inch i.d.for low-pressure drop applications* 
• Heavy-duty wall thickness for durability
• Self-weighted for easy installation
• Kink proof & puncture resistant
• Available in 100 ft. (boxed) and 200ft and 500ft (rolls) lengths
• Also available in custom sizes (3/8″, .58″, 3/4″, 1″, 1.25″ and  1.5″) diameter in custom lengths.
• 10-year warranty (best in the industry)

* DownUnder™  air supply tubing is also available in 3/8 inch i.d. (.375 in) for smaller pond and lake applications

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.
