Bubble Blaster rotor employs a high cluster pin-wheel impeller which slices through the bubbles and injects them into the water column producing mass amounts of minute microbubbles. This produces a pillow of surface area to extract dissolved organics from the water column. The Bubble Blaster impeller bearing and shaft is made of Silicon Nitride, unlike other ceramics, Silicon Nitride has superior wear-resistance, self-smooth nature and deters calcium build up. Therefore reducing maintenance frequencies and ensure a longer operating life.
