Perfect for deep ponds that need to push a lot of oxygen. The Vertex Air 1XL5-aerator has Vertex’s latest technology to provide the most aeration for your money. Designed for larger ponds with depths greater than 8 feet an Air 1XL5-can aerate approximately 2.0-4.0 acres depending on shape, slope, depth, oxygen demand and other factors. A super-duty Brookwood-twin cylinder HighFlow- compressor, housed in our rustproof aluminum outdoor cabinet, feeds a bottom mounted XL5 AirStation- utilizing five MicronBubble-diffusers. The rising force of millions of bubbles circulates the entire water column, entraining bottom water up to the surface allowing vital oxygen to be absorbed and poisonous gases expelled. With no electricity in the water, Vertex’s aeration systems are safe for most any type of water recreation. Our compressor systems have a full two-year warranty plus a limited lifetime cabinet warranty against rust. Our Stations carry a five-year warranty and BottomLine has a 15-year limited warranty.
