No negative pressure frequency conversion water supply equipment: 
 An advanced technology: the device will inhibit the vacuum technology, fluid control technology and intelligent frequency conversion technology, a number of advanced technology to optimize the integration of water supply equipment and water pipe network directly connected in series to achieve regulation, energy, health, safety and reliable operation of not produce negative pressure, do not build pools, water tanks. 
 2, no pollution of Health: Equipment for the entire seal structure to prevent the water source of secondary pollution and water supply water pollution problems. 
 3, the energy saving effect significant: fully enclosed structure run, to avoid infiltration, run, run, drip, leak, and other phenomena occur, no pool, water tank, saving disinfection rinse water. Directly connected in series with the water pipe network, can take advantage of the water of the original pressure, the number of poor make up the number of water to meet the requirements when the equipment stops working. The equipment most of the time running at lower frequencies, less power consumption. Inverter technology, further energy saving, energy-saving in general up to 50%.
