The ST164 Chemical Injector is a stainless‑steel foam‑generation module engineered for professional cleaning systems. Designed to work in combination with compressed air, it produces a drier, more adhesive foam ideal for applications requiring maximum cling and coverage. The injector must be paired with a DN12 hose and a wash gun featuring 1/2" inlet and outlet connections to ensure optimal performance.

This versatile injector accommodates two separate chemical feeds, allowing operators to switch between products instantly by adjusting the selector lever. Its dual‑chemical capability streamlines workflow, reduces downtime, and enhances efficiency across a wide range of cleaning tasks.
