Sun KRF Automatic Filters are perfect solutions to protect the main process lines from heavy dirt loads and big prticles. KRF Series consist of heavy duty filters with an electric self-cleaning mechanism. The KRF Series range in flow rates up to 4.500 m3/h, with screens designed ranging from 5.000 - 200 micron filtration degree. Inlet/ Outlet flanges are available up to 32” diameter.
Raw water enters the inside of Sun patented “cross screen” cylinder from the filter’s inlet an flows through the screen to the filter’s outlet. The gradual dirt building up on the inner screen surface causes a filter cake to develop with a corresponding increase in the pressure differential across the screen. A pressure differential switch senses the pressure differential when it reaches the preset value or after a presettime has elapsed, the cleaning process begins.
Cleaning of the filter is carried out by a brush system. The exhaust valve opens and drive unit starts to rotate the stainless steel / nylon brushes, which sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the brushes and flushed out the exhaust valve. During the self-cleaning process, filtered water continues to flow. Self-cleaning proces is adjustable related to the dirt load.
The control system comprise of a pressure differential switch that senses the pressure differential across the screen and sends a signal to the control board when it reaches a pre-defined value (usually 0,5 bar / 7 psi), or when the predefined time elapsed the control board initiates the self-cleaning process.
The filter begins a self-cleaning cycle under any one of the following conditions;
1- Receiving a signal from the pressure differential switch.
2- Time interval parameter set at control board.
3- Manual start.
