OVERVIEW & BENEFITS
The 3/8″ Fixed Acid Chemical Injector (Model 6633) is a high-performance downstream injector designed for use with acidic and low pH chemical solutions. With a 2.3mm fixed orifice, this injector provides consistent chemical draw across systems operating in compatible GPM and PSI ranges, making it ideal for softwash, fleet washing, and equipment cleaning applications.
Built from acid-resistant materials, the 6633 injector is suited for harsh environments and designed to be integrated into downstream injection setups with reliability and safety.
