OVERVIEW & BENEFITS
The 3/8″ Fixed Acid Chemical Injector (Model 22.0321) is built for precise and reliable downstream chemical injection of low pH or acid-based solutions. Designed with a 2.1mm fixed orifice, this injector supports consistent chemical draw rates across compatible pressure washing and softwash systems.
This unit is ideal for use in environments requiring acid-resistant components, such as fleet washing, restoration, concrete cleaning, and equipment maintenance. It features durable construction with components that resist corrosion caused by aggressive cleaners.
