Whether you're applying house wash, roof cleaning chemicals, or concrete cleaners, downstream injectors provide safe, efficient chemical delivery without exposing your pump to harsh chemicals. These systems draw chemical from a bucket or tank and inject it into the discharge stream after the pump, protecting equipment while delivering professional results. All injectors are sized by GPM rating to match your pressure washer flow for optimal chemical draw performance.
