The 1 1/2" T2C filter unit is used for the same purposes as the 3/4" and 1" filter units, but with its larger size, has additional applications as well. The 1 1/2" unit is used often for filtering the irrigation mainline to help keep all sprinkler nozzles clean and operating properly. This unit is also used on commercial properties or apartment complexes. With the large filter element surface area (25 in2) and bowl size larger than many other similar sized filter units in the market, this filter works great when more holding capacity of debris or time between flushing is required. Manufacturers rely on the 1 1/2" TwistIIClean filter unit to help keep their production equipment clear of debris on loop systems or water cooling systems, saving them time since they do not have to shut down the line to clean the filter. With a max flow rate of 78 gpm, this unit works well in a variety of applications.
