Why Choose Airmax Shallow Water Series SW20 1/4 Acre Aeration System ?
ProAir 2 Weighted Diffuser for Ponds – High-Efficiency Aeration with Low Maintenance
Improve water quality and oxygen levels in your pond with the ProAir 2 Weighted Diffuser, designed for maximum oxygen uptake and energy-efficient aeration. This diffuser features high-performance membrane sticks that produce a dense cloud of micro-bubbles, delivering optimal oxygen transfer throughout the water column.
Unlike traditional air stones, the ProAir 2’s membrane design is crack-resistant and maintenance-free, eliminating the need for acid-washing or frequent replacements. The integrated check valve protects your aeration system by preventing water from flowing back into the compressor.
Its self-weighted sled base keeps the unit submerged and upright, making installation fast and secure. Ideal for ponds, lakes, and water features, the ProAir 2 is backed by a 5-year warranty for long-term peace of mind.
AirMax SW 20 Linear Diaphragm Compressor
At the heart of every Shallow Water Series Aeration System is the LR25 or LR50 Linear Diaphragm Compressor, engineered for energy efficiency and ultra-quiet 115V operation. Rubber mounting feet minimize vibration and noise, making it ideal for residential and small commercial ponds.
The LR25 compressor, featured in the SW20 system, delivers up to 2.5 CFM of oxygen to your pond—all while operating for as little as $3.60 per month in electricity costs. Built for reliability and backed by a 3-year warranty, it’s the perfect choice for shallow water aeration with minimal noise and maximum performance.
Composite Cabinet
Protect your aeration system with this ETL-certified composite cabinet, designed for quiet operation and a faux rock exterior that blends seamlessly into any landscape. The cabinet features a removable top and high-density side air intake filter, shielding internal components from dust, debris, and pests while allowing easy access to the pre-wired electrical box and compressor.
Built with durability in mind, the cabinet includes an elevated base to guard against flood damage, and an integrated ventilation fan with a rain shroud to prevent overheating and moisture intrusion.
Dimensions: 23"L x 17"W x 15"H
Warranty: Backed by a full 10-year warranty for long-lasting peace of mind.

Frequently Asked Questions
Need more information? You can find it here.
A pond aerator increases oxygen levels, improves water circulation, reduces algae growth, prevents fish kills, and eliminates foul odors caused by stagnant water.
The right aerator depends on your pond’s size, depth, and shape. Deeper ponds require bottom-diffused aeration, while shallower ponds may benefit from surface aerators or fountains.
Bottom-diffused aerators push air to the pond’s bottom, efficiently circulating water in deeper ponds. Surface aerators or fountains create surface movement, providing oxygen to the upper layers and offering visual appeal.
Energy consumption varies by model and horsepower. Many aerators are designed to run 24/7 with efficient, low-power compressors to minimize electricity costs.
Yes! Aerators help prevent winter fish kills by keeping a portion of the pond ice-free, allowing for gas exchange. However, in extremely cold climates, adjusting placement or reducing operation may be necessary.
Most high-quality aerators operate quietly, with sound-dampening enclosures available. The compressor should be placed on dry, level ground near a power source, ideally in a ventilated cabinet for protection.
Regular maintenance includes cleaning air filters, checking airline tubing and diffusers for clogs, and ensuring the compressor is functioning properly. Most aerators are designed for minimal upkeep and long-term performance.
