High Purity Venturi Injector GRaphics

High Purity Venturi Injector

The High Purity Venturi Injector is a precision-engineered device used to accurately inject or dose chemicals and gases into a flowing fluid stream through vacuum-induced suction. Built from high-purity, chemically resistant materials such as PFA, PVDF, or PTFE, this injector operates without moving parts, ensuring contamination-free operation in ultra-clean fluid systems. It is commonly used for mixing, dosing, and blending in high-purity process applications where consistent chemical delivery and system cleanliness are critical.

Key Features of High Purity Venturi Injector

  • High-Purity Construction: Made from PFA, PVDF, or PTFE for ultra-clean fluid handling and corrosion resistance.
  • Vacuum-Induced Injection: Utilizes fluid velocity to create suction without external power or moving parts.
  • Non-Metallic, Inert Design: Ensures full chemical compatibility and no metallic ion leaching.
  • Compact and Efficient: Simple design with high reliability and minimal maintenance requirements.
  • Smooth Internal Surfaces: Reduces particle shedding and supports laminar flow.
  • Cleanroom Manufactured: Assembled and packaged in ISO Class 100 or better environments.
  • Compliant Materials: Meets SEMI F57, FDA, and USP Class VI purity and safety standards.
