Due to the effect of centrifugal force, when the impeller rotates, the wind vane makes the air forward move and become a series of spiral movements. Spiral Air between the impeller blades will speed up rotates and sucks outside air into the side channel (via suction mouth). After the air is sucked into the side channel, it will be compressed and then return to between the impeller blades and speed up rotation again. When the air along a spiral orbit goes through the impeller and side channel, each impeller blade increased compression and speed, along with the rotation of air’s kinetic energy increased making the pressure of air that goes through the side channel increase. When the air arrives at the junction of side channel and discharge flange (the side channel will turn narrow at the exit) it will be pushed to mufflers and discharged out of the air blower.

Reduced power cost: Benefits of Nano-Tube/aerotube/air hose technology include reduced energy costs, higher ratio of oxygen / kWh transfer due to fine bubbles. Because low air resistance combines with thousands of tiny pores on the tube, power consumption is low, performance of oxygen transfer is effective.

The integrated RAS equipment is a complete system designed for simple setup, easy maintenance, and reasonable cost. The design is flexible for a wide range of applications including saltwater or freshwater holding, rearing, aquaponics, and more. We can make a reservation according to the customer’s request.
