Band Filtration System

The Band Filtration System works on the principle of hydrostatic pressure and gravity with zero leakage in filtration chamber due to perfect custom built system to suit a given application. Suitable filter media is used to achieve good filtration efficiency. This system is used for individual machines and also for multiple machines. Construction and working principle: the system consists of two circular disc wheels duly mounted on central pipe connecting to hollow shaft, which keeps rolling on a honeycomb belt on the disc axis. Filter media is allowed to pass between disc and the honeycomb belt with no relative motion. So perfect sealing is achieved for zero leakage and efficient filtration. The dirty coolant is allowed to enter through the centre hollow shaft having multiple pouring slots inside for uniform distribution over the filtration bed. Good hydrostatic head results in building up of dirt layer cake within itself, which enhances filtration efficiency. As the dirty coolant rises to a certain level, the level sensor signals the geared motor to drive the honeycomb belt, allowing the new media to pass gradually inside for fresh filtration and at the same time to removing the used media along with the dirt cake. The filtered coolant comes out from the bottom into a clean tank for pumping back into the machine.
