Pentair's subordinate water group is the world's largest professional water treatment equipment manufacturing company, as early as 2003 through the acquisition of Aihuipu to complete the complete layout of the water purification market, in 2016 was the famous water resources information magazine GWI listed as one of the world's most authoritative water treatment companies, the United States White House, Beijing Diaoyutai have selected Pentair's water purification treatment program.
In addition to the conventional stainless steel pre-water filter, Pentair also has a special type of product - PP cotton filter element pre-bottle, known as "fat bottle", sought after by many people, its advantage is that the filtration accuracy is high, PP cotton filter element can reach 5 micron filtration accuracy, much higher than 40-60 micron filter screen water filter, and the filter element is very cheap, a PP cotton filter element only needs about 10 yuan, can be used for 3-6 months.
However, the "fat bottle" is certainly not as convenient as the filter water filter with cleaning function, and the PP cotton filter element needs to be replaced regularly, and the official installation is not included, so the user needs to have a certain hands-on ability.
Pentair's stainless steel pre-filter is also excellent, and its workmanship is more prominent: like B140-B1104, its filter bottle glass is made of BPA-free material, which ensures water safety, and its performance is also remarkable: its flow rate can reach 4 tons per hour, which is higher than the 2-3 tons of mainstream products, and the 316 stainless steel filter screen with 40 micron accuracy is at the mainstream level.
The B140-B1104 also comes with a water pressure gauge and a date dial, which can monitor the water pressure in real time and record the month of cleaning to remind the user to clean regularly. In addition, although B140-B1104 is claimed to be able to resist low temperatures of minus 30 degrees, it is recommended to install it indoors because the working temperature of the general pre-filter is more than 5 degrees Celsius, so as to avoid bottle bursting due to cold weather. The B140-B1104 is priced at about 1,000 yuan, and the overall performance is quite good, so it is worth buying.
In addition to the function of general pre-filter, Pentair BF-06-B also has its own pressure reducing regulator to avoid water leakage caused by high water pressure, and its voltage regulator has a reading plate, which can achieve precise pressure control, but the flushing method of BF-06-B is still a direct flush type, and the effect is not as good as that of a backwash water filter.
