ST-164 INJECTOR WITH COMPRESSED AIR MODULE please select nozzle size required.

Overview

ST164 twin chemical injector with compressed air module from R+M Suttner in stainless steel. Water is forced through a restrictive orifice, and with a low pressure nozzle such as an ST75 foam head this creates a vacuum that draws chemical into the water stream. A lever selects which of two connected chemicals is drawn in. It is used for cleaning in agriculture, automotive and food processing, including vehicles that carry livestock. Choose the injector size, from 1.2mm to 2.8mm, when ordering.

A compressed air connection gives a drier, stickier foam; with compressed air, use DN12 hose and a 1/2" inlet and outlet wash gun with a large cross section, such as the ST2720, ST2725, ST3100 or ST3300, so the foam does not collapse. A lance with an air injector is not needed. Ten dosing nozzle inserts are supplied to adjust the chemical dose. Fit a chemical filter on the end of each chemical tube and check the viscosity of the chemical, as it affects the draw rate. It has a 3/8" BSP female inlet and a 1/2" BSP female outlet and is rated to 350 bar, 80 litres per minute and 100°C.
