It is easy to install and maintain and features quiet operation. These systems do not require electricity in the water, making it safe for swimming. - Robust-Aire is a beneficial mixing system for ponds and lakes. A shore-mounted compressor pushes air through self-weighted lines to a dual-loop diffuser at the bottom of the pond or lake. The diffuser then continuously releases micro-bubbles that rise to the surface, carrying large volumes of water. This mixing process increases oxygen transfer which improves water quality, expands fish habitats, decreases muck, and much more. - Robust-Aire Diffused Aeration Systems help eliminate thermal and chemical stratification in ponds and lakes. Stratification occurs when water is layered by temperatures and/or chemical properties and density. This can lead to a number of problems such as reduced oxygen levels and an increase in nutrients on the pond or lake bottom which causes unwanted plant growth, foul odors, and more. - The RA2-PM system includes all the essential components for efficient aeration. The Post Mount Cabinet can be attached to a post or vertical wall with the included hardware. The 1/4HP 120V compressor is designed and built to meet the demands of continuous-duty, year-round, large aeration applications. The dual-loop diffuser is clog-resistant and provides high volumes of upward water movement for thorough mixing. This system includes 2 rolls (100 ft. each) of 3/8 in. tubing. - The dual-loop diffuser and Post Mount Cabinet are backed by a lifetime warranty, ensuring long-term performance and reliability. The compressor motor is covered by a warranty for 3 years, providing reliable operation and the piston cups and cylinder of the compressor are covered by a warranty for 2 years. Tubing has a 15-year warranty. ## Images ![KascoRobust-Aire Diffused Aeration System – Post Mount – 2 Diffuser, 1/4HP, 120V Pond Aeration – RA2-PM - Image 1](https://m.media-amazon.com/images/I/610jdhNbWzL.jpg) ![KascoRobust-Aire Diffused Aeration System – Post Mount – 2 Diffuser, 1/4HP, 120V Pond Aeration – RA2-PM - Image 2](https://m.media-amazon.com/images/I/517hn-EcBhS.jpg) ![KascoRobust-Aire Diffused Aeration System – Post Mount – 2 Diffuser, 1/4HP, 120V Pond Aeration – RA2-PM - Image 3](https://m.media-amazon.com/images/I/61QeLnLIF3L.jpg) ![KascoRobust-Aire Diffused Aeration System – Post Mount – 2 Diffuser, 1/4HP, 120V Pond Aeration – RA2-PM - Image 4](https://m.media-amazon.com/images/I/41E0iUh20dS.jpg) ![KascoRobust-Aire Diffused Aeration System – Post Mount – 2 Diffuser, 1/4HP, 120V Pond Aeration – RA2-PM - Image 5](https://m.media-amazon.com/images/I/81STJtiKbwL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/57749966-kascorobust-aire-diffused-aeration-system-post-mount-2-diffuser-1](https://www.desertcart.at/products/57749966-kascorobust-aire-diffused-aeration-system-post-mount-2-diffuser-1) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-03*
