Principle

Automatic self-clean filter is make up of filter tank, filter element, self-cleaning part, gearbox and electrically valve. Clean water will through the filter element, and the impurity and particle bigger than the filter pore will be intercept, then the float and pellet cannot enter water supply line. When the pressure difference higher than 0.02～0.05MPa, the drain valve will be open by pressure difference controller, the system automatic back cleaning, the impurity and particle discharge from drain outlet.

Characteristics

• pressure lost of self-cleaning: 0.02MPa
• Water demand for self-cleaning: 0.5% of design flow.
• Minimum work pressure: 0.3MPa
• Max work temperature: 65℃
• Current: 220VAC、380VAC
