ProLake Aeration Systems are designed to clean and clear smaller ponds and lakes measuring up to 5 surface acres. ProLake1 systems offer a powerful ½ horsepower compressor capable of delivering 5.3 cubic feet of air per minute to the non-clogging, self-cleaning Duraplate diffusers. We top it all off with high volume cooling blowers, a programmable timer and fully adjustable, brushed aluminum manifolds. All housed in a durable, sound-deadening cabinet backed by a lifetime warranty. The result is a high-end, energy efficient aeration system that will keep your pond clean and problem free for many years to come.
