Grovhac, Inc.
The 1-33-RXP gen-Air-ator pond aerator is a product scientifically engineered for the preservation, enhancement, and enjoyment of our environment. The gen-Air-ator is a complete pond aeration system, which includes a powerful and economical 1/3 HP compressor (protected from the elements by a durable steel housing), 400 ft of poly air pipe, and a lake bed diffuser. This system aerates a pond or lake by pumping oxygen to the lake bed, thereby purifying the water and protecting it from an overload of organic build-up. In addition, the plume created from the millions of rising bubbles helps keep the water open year round, resulting in increased yields of both fish and fowl. Designed to 'give your pond a breath of fresh air', the gen-Air-ator is the best aeration system available anywhere.
