Automatic Self Cleaning Horizontal Filters

OPERATION PRINCIPLE

AutoFlush® series can do automatic cleaning without any need for external power supply or optionally with electrical activation from a distance. The filter screen can achieve filtration rates from 25 m³/h to 180 m³/h. Standard filter screen size is 130 microns and inlet/exit pipe diameters are available between 2” to 8”.

FILTRATION METHOD

Filtration starts as the dirty water enters the coarse screen from the inlet. In order to protect the fine filter, large particles are filtered on the coarse filter. Water then passes through the fine filter, particles are captured by the fine filter, and clean water leaves from the outlet. Particles gradually accumulating on the fine filter, increases the pressure difference. Once the pressure difference exceeds the preset pressure differential value, filter automatically starts to clean itself.

CLEANING METHOD

Once the pressure difference exceeds the preset pressure differential value, hydraulic control unit opens the drainage valve and the cleaning cycle starts. Particles accumulated on the fine filter, are sucked by the nozzles and the turbine and discharged from the drainage pipe. Thus cleaning operation is achieved. Filtration is not interrupted and AutoFlush® continues filtration during the cleaning cycle.
