Adjustable Downstream Chemical Injector – 3/8" MPT 1.8mm Orifice

Adjustable Downstream Chemical Injector – 3/8" MPT (Ceramic Ball & Inconel Seat)

Built for professional pressure washing systems, this Adjustable Chemical Injector delivers dependable downstream chemical application with the durability contractors expect from Daytona Pressure equipment. Designed to operate after the pump and unloader, it uses the Venturi effect to create strong vacuum draw when switching to low pressure — making it ideal for house washing, softwash setups, and general exterior cleaning.

This adjustable version allows you to fine-tune your chemical ratio, giving you more control over your downstream mix compared to fixed injectors.

✔ Adjustable Chemical Draw – Control mix ratios from approximately 20% down to 3%.
✔ Stainless Steel Internal Components – Ball and seat designed for corrosion resistance and long service life.
✔ Venturi-Driven Injection – Creates vacuum when low pressure is activated for reliable downstream performance.
✔ Contractor-Grade Reliability – Built for residential, commercial, and fleet washing setups.
✔ Universal Inline Installation – Simple replacement or upgrade for most pressure washing systems.

⚙️ How It Works

Downstream injection happens after the pump and unloader. When the low-pressure side of a dual lance is opened, the injector’s orifice becomes the restriction point, creating vacuum that draws chemical into the line.

While injectors can pull up to 20% chemical draw, most real-world setups average 12%–18% due to system restrictions.
