BWT filters



Filters with automatic backwash RF-A

Filter RF-A (Corporation BWT) is used to filter drinking water and process water. It protects the water pipes and the connected components (valves, equipment, boilers, production units) from functional disturbances and corrosion caused by exposure to impurities. The filter can also be used to filter the well, boiler make-up, process and cooling water.


During the filtration, raw water passes through the filter element. Thus, depending on the type of filter retains particles> 100 .mu.m or> 200 .mu.m. These particles fall directly into the lower part of the housing or retained on the inner surface of the filter element. Backwash valve opens at the output of the wash water. Segments of the suction ring element backwash move along the bottom surface of the filter and back up and sucked into the filtration surface dirt. Backwashing starts automatically as a result of contamination of the filter element value of the differential pressure reaches 0.8 bar (factory setting). If this pressure difference is not reached within a predetermined time interval, backwashing begins at the end of this interval.
By electronic control units can be connected in parallel to 4 filters.

Installation, working conditions

Filter at a distance about 1,2 m should be a separate electrical outlet (230V ~ / 50Hz). Shall be a continuous supply of electricity. The feed rate of water during flushing backwash models for RF and RF 65 A 80 A should be at least 10 m3 / hour for model A RF 100 and RF 125 - at least 14 m3 / hour. Protect from strong pressure shocks (for example, when closing the solenoid valve after the filter).
