Float type aerator is a new type of submersible aerator, which is an improvement on the original submersible centrifugal aerator. The installation form of the original submersible aerator, which was positioned at the bottom of the pool by its own weight, has been changed to a form that uses dual inlet pipes and is suspended on the water surface by a float. Easy installation and maintenance, no need to operate in the pool, just lift out the equipment.
