Airmax Shallow Water SW20HP Pond Aeration System - Uses 5/8" Airline Only Ordered Separately

The Airmax SW20HP aeration system is designed to be used in ponds up to 1/4 acre and up to 10' in depth. 

The image above is for illustrative purposes only. This system does not include airline which must be ordered separately.  Use 5/8" weighted airline only.

What we like:

The Airmax SW20HP uses a 1/4 HP rocking piston compressor to power two diffusers that are ideally suited to ponds that have shallow to medium depths up to 10 to 12 feet.  The pump is available in 115v or 230v (optional) and produces 2.3 CFMs while costing around $10 to $15 a month to run 24/7. 

Air is directed to each diffuser via a two valve manifold so you can control air output precisely out of each diffuser.  This works particularly well for winter usage to protect fish where you may want to turn the deeper diffuser off and only aerate from the shallow area. 

Standard Airmax Composite Cabinet - ETL electrical safety certified composite cabinet has a quiet design with a faux rock finish to blend into any landscape. The removable top and side high density air intake filter protects the compressor and pre-wired electrical box from dust, dirt, and debris, while providing easy access. Other cabinet features include an elevated base protecting against damaging flood water and a exhaust fan with rain shroud cools and protects against moisture and heat damage. Standard cabinet dimensions: 23"L x 17"W x 15"H

SilentAir Compressor with SmartStart Technology - The Shallow Water HP Series Aeration System uses a powerful whisper-quiet SilentAir RP25 1/4 HP Rocking Piston Compressor built with SmartStart Technology to protect compressor during pressurized restarts following power supply interruptions.

ProAir2 Weighted Diffusers - Designed for maximum effect, 2 ProAir 2 Weighted Diffusers incorporates high-efficiency low-maintenance rubber diffusion sticks to release tiny air bubbles into the water column. These diffusers have the synergy of air stones without the issues of cracking and acid-washing. The ProAir 2 Weighted Diffuser has an integrated check valve to prevent back-pressure on the compressor. The innovative sled design keeps the ProAir 2 submerged while maintaining the proper, right side up position during installation. Comes with a 5-year warranty.
