There are 4 different types of filters that Toro offers. (Figure 1) Figure 1 1. The first type is the basket filter that sits in the tank. (Figure 2) This filter helps keeps the bigger debris out of the spray tank and out of the spray system. This is the first line of defense. There is only one mesh size for the basket filter in the Multi Pro sprayers.
PAGE 3
2. The second type is the suction filter. This filter is located on the top of the tank, in the suction line going to the spray pump. (Figure 3) This filter protects the pump and other components downstream. If this filter becomes partially blocked, it can cause a restriction in the suction line, resulting in pump cavitation, greatly shortening the life of the pump. Figure 3 There are 3 different mesh sizes for the suction filter: 30 mesh, 50 mesh, and 80 mesh.
PAGE 4
Filter Mesh Size: 30, 50, 100 Figure 4 3. The next type is an inline pressure filter located after the pump and before the valves. (Figure 5) This filter protects the valves in the spray system. If this filter becomes blocked, it will restrict flow and system pressure will increase until the pressure filter ruptures.
PAGE 5
There are five different sizes of pressure filters; 16 mesh, 30 mesh, 50 mesh, 80 mesh, and 100 mesh. (Figure 6) The factory equipped filter size is 50 mesh. This is sized based on the viscosity of plain water. It is recommended to size the suction filter based on the nozzle size, the viscosity of the chemicals being used, and the chosen application rate. The pressure filter is sized according to the nozzles that are selected (refer to Table 3).
PAGE 6
Figure 7 Filter Mesh Size: 50, 100 Figure 8 The filters used in Toro Multi Pro sprayers are color coded for quick identification. This color coding reflects the mesh size of the filter. Prior to 2016, the color code was vendor dependent, as different vendors used their own color-coding system. In 2016, the filter color codes were moved to standardized color codes. With the implementation, there are previous filters that are still using the old color code.
