What's a sparger?
Unless you're a competitive diver or coach, you might not know much about sparger systems -- many of our clients were unfamiliar with the concept of air safety sparger systems until a new swim program or pool renovation project required it.
An air safety cushion sparger system is simply a device that provides instant mounds of highly aerated water in the diver's entry area to prevent injury and aid training. Because divers can't always nail the perfect dive on the first try, the air sparger system allows the diver to practice in a safe environment.
How does it work?
High-grade stainless steel and PVC sparger nozzles (diffusers) are installed in the pool floor directly under the diving boards or platforms to provide a mound of bubbles to cushion the diver’s
impact into the water. The bubbles also provide the diver with a clear visual reference on the water's surface.
The bubble action is activated on-demand by the coach or trainer using a hand-held remote control that starts and stops the release of air. The bubbling action normally lasts several seconds, allowing adequate time to coordinate the air release with the diver’s entry into the water.
The sparger nozzles are supplied by a high capacity compressor and storage tank, which are located in a remote mechanical room or service area. Air safety cushion systems can be installed for permanent or removable use, either during new construction or for existing pools.
History
The first air cushion was installed at Point Claire, Québec, and the systems are now used throughout the United States, Canada and Europe.
Initial installations were typically found in Olympic-caliber facilities such as the Indiana University Natatorium in Indianapolis, and the King County Aquatic Center in Seattle, Washington. Since the initial introduction in 1971, air cushion safety cushion sparger systems have become a requirement for most facilities with a competitive diving and training program.
