Overview
RM Suttner ST166 Injector
The easyfoam365+ ST166 Injector is a versatile injector designed for applications involving the use of chemicals and foam, such as cleaning and sanitation tasks. Here’s a detailed breakdown of its features and specifications.
Dual Chemical Injection: The injector is capable of sucking in and admixing up to two chemicals simultaneously, allowing for efficient and effective chemical distribution.
Adjustable Chemical Dosing: The chemical dosing can be precisely controlled using 2 sets of 10 exchangeable nozzle inserts, which range in size from 0.5 mm to 2.0 mm. This provides flexibility in managing the concentration of chemicals being used.
High-Pressure and Temperature Tolerance: The injector can operate at a maximum pressure of 350 bar (approximately 5076 psi) and a maximum temperature of 90 °C (194 °F), making it suitable for a variety of demanding industrial applications.
Connection Size: 3/8" female thread (F) on one end and 3/8" male thread (M) on the other.
Hose Tails: Comes with two hose tails sized at 9 mm each for connecting hoses.
Material and Build: Designed to withstand high pressure and temperature conditions typically found in industrial environments.

You will need to know the flow rate and pressure of the pressure washer or system that the injector is to be installed.
Firstly select the closest flow rate (round up if required)
Then move right across the chart until you are at the closest pressure column.
The top number (1.6) is the injector size.
For foam injectors not using compressed air the number in brackets underneath is the correct ST75 foam lance size required.
