PowerVac G G3, PowerVac G G5, PowerVac G G7, PowerVac G G6, PowerVac G G10, PowerVac G G14 are designed for dental practices to efficiently remove waste from the operatory. The system utilizes a separator tank to collect water and solids, which are then drained away. The vacuum pump helps to maintain a constant suction pressure for reliable performance. A variable frequency drive (VFD) adjusts the motor speed based on the vacuum demand.
