Feed screw 1.7 m
Complete feed screw with metal inlet and with plastic pipe. Delivered unassembled. Fits burners up to 30 kW.
We supply as standard a screw of approx. 1.7 meters, but it is of course possible to order longer spirals, since the screw is constructed in parts consisting of screw motor, spiral, T-tube and bottom tube. The PVC intermediate tube is easily cut to the right length after the coil. We recommend that you do not exceed 2 meters as the feed gets worse with longer spirals. Then air pockets most often occur which cause the fuel to be fed unevenly to the burner and consequently worse combustion rate. For longer spirals, the screw motor can also work harder and have a shorter service life. Therefore, we recommend our external dosing screw for better operation.
