1.Technology Filter making material: the filter is made of PVDF membrane, a better ultra filter material. PVDF is a strength, corrosionresistant substance. The head is made of FOOD GRADE PP, and the coagulum is epoxy resin medical material. The waterproof ring is made of silica gel medical material. 2.Be used to purify well water Be used for water filter equipment in farms and houses using well water.

By opening the blowdown valve, the water stream will clean the filter and drain out from the blowdown outlet. When you want to clean the filter by hand, it is very easy to open the cover and take out the filter. It has an output of 1000 L/H and a filtration of 0.01 micron, making it suitable for purifying well water. 3.Be used for whole house water filter It has outputs of 600/1000/2000/3000 L/H, sufficient for the whole house water demand. With a filtration of 0.01 micron and designed to drain out from the blowdown valve, it can be used for whole house water filtration. The purified water meets the drinkable requirement from the municipal water source, protecting the appliances and water pipes in the house. 4.House making material The housing is made of SUS 304, safe for household water and with a longer service life.
