1μmPPF FilterThe pore size of the PPF filter is 1 micron, which furtherremoves smaller particles, suspended solids, and colloids in water. Low-Pressure SwitchWhen the water pressure reaches 1.5kg/cm2, the power supplyis turned on to operate the machine normally. When there is nowater or the water pressure does not reach 1.5kg/cm2, theequipment automatically cuts off the power, and there is anindicator light on the microcomputer control box. Inlet Solenoid ValveWhen the power is turned on, tap water passes through theinlet solenoid valve to enable normal water production by the A1processor. When the machine stops, the water source is cut off toprevent water from passing through and being discharged throughthe concentrate water route. High-Pressure PumpPressurizes tap water to 5-8 kg/cm2 to meet the pressure andflow rate requirements of the RO membrane for water productionFlush Solenoid ValveAutomatically controlled by the machine (PCB), theA1 processor accumulates 7.5 hours of work time, and thepower is turned on once to perform high-pressure andhigh-flow flushing of the RO membrane, with a flushingtime of 1 minute and 40 seconds.Ion Filter Membrane QL1016The QL1016 ion filter membrane with a pore size of 0.0001microns can remove impurities such as bacteria, viruses, heavymetal ions, etc., from water. After passing through the QL1016 ionfilter membrane, more than 98% of ions and other soluble solids inthe water can be effectively removed
