Upgrade your pressure washing system with our premium Adjustable Acid Chemical Injector, engineered for superior chemical application, precise dilution control, and maximum corrosion resistance. Designed specifically for downstream chemical injection systems, this adjustable chem injector gives professionals the ability to fine-tune chemical draw rates from as high as 20% down to as low as 3%, making it ideal for soft washing, house washing, fleet cleaning, roof cleaning, and acid application.
Unlike standard fixed chemical injectors, this acid-rated adjustable injector is built with enhanced corrosion-resistant materials including a ceramic ball and Inconel stainless steel seat, providing long-lasting durability when handling harsh chemicals, sodium hypochlorite, acids, degreasers, and other aggressive cleaning solutions. Whether you’re a professional pressure washing contractor or industrial cleaning operator, this injector delivers reliable performance in demanding environments.
How Downstream Chemical Injectors Work
Fixed and adjustable chemical injectors operate using the Venturi effect in a downstream injection system. Installed after the pressure washer pump and unloader, the injector creates a vacuum when the low-pressure side of a dual lance or soap nozzle is activated. This vacuum draws chemical into the water stream for safe and efficient application. While all chemical injectors can achieve a maximum draw rate of approximately 20%, most real-world systems average between 12%–18% due to flow restrictions throughout the setup.
The key advantage of an adjustable chem injector is the ability to customize your soap-to-water ratio without changing injectors. This allows users to reduce chemical consumption, improve application accuracy, and adapt to different cleaning jobs instantly.
Key Features:

Choosing the Correct Chem Injector
Chemical injectors should always be sized according to your pressure washer’s GPM (gallons per minute) flow rate restriction to ensure proper performance and chemical draw. Selecting the correct injector size improves efficiency, consistency, and injector lifespan.
