Submersible Jet Aerator- JA utilizes the rotation of the impeller coupled directly to the motor to create a centrifugal force, which makes local low pressure stuck in water. Meanwhile the entrance of the impeller results in vacuum to draw air from atmosphere. Water and air mix in channel of aeration Housing. The air-water-mixture current is discharged speedily by centrifugal force. Due to the water spurting extremely strong, make fluid create convection & circulation effectively. Moreover the air becomes tiny bubbles. On the one hand the bubbles rise slowly; on the other hand the atmosphere oxygen is dissolved in water. Because the bubbles are tiny & numberless their surface area is large, it makes the oxygen transfer rate of unit BHP higher than other type of aerator. Additional Information: Item Code: JA-1
