Fume Hoods for Wet Chemical Processes

  • System Description
  • Common Applications
  • Common Configurations

A fume hood offers a safe way to contain and ventilate hazardous fumes. Wet chemical processes often call for the use of a fume hood. Industrial chemical fume hoods are used in a variety of applications, from laboratory chemical research to full-scale manufacturing with wet chemical processes like semiconductor wafer processing, passivation, and part etching.

Typical construction materials for industrial fume hoods depend on the chemical handling properties required for the application, but commonly can include: polypropylene, PVDF, Teflon® / PFA, or ECTFE (HALAR®). Lab fume hoods can be as simple as polypropylene polymer-based tanks with an enclosure to contain and ventilate vapors from the manufacturing or lab process.

Below are a few examples of systems built for customers in various applications and industries like: semiconductor, medical device, and aerospace.

Fume Hood for Wet Chemical Processes

Fume Hood for Wet Chemical Process
This fume hood is constructed of polypropylene. Air channels built into the enclosure connect to customer-supplied blowers and ventilation to process fumes through facility exhaust.

Best Technology offers a full line of custom polypropylene fume hoods. Our well-ventilated process enclosures protect machine operators and your manufacturing floor from chemical fumes.

Fume Hood for Semiconductor Wafer Chemical Processing

Fume Hood for Semiconductor Wafer Chemical Processing - Sliding Door Up

System includes large integrated PVDF tanks with water, air and nitrogen guns and magnehelic pressure gauge for ensuring proper ventilation requirements.

Fume Hood for 3-Stage Chemical Etching Passivation

Enclosed Vented Fume Hood for Nitric Acid Passivation and Etching

System includes rear tank venting on two tanks and fresh water rinse in the third tank.

Multistage Wet Process Fume Hood with In-Tank Heat and Circulation Pumps

Multistage Fume Hood

System includes rear tank venting exhausted from top of system, with integrated rectifiers for electropolishing and pumps for electrolyte circulation. Example process steps for this fume hood include:

  1. Surface Preparation: Clean and Rinse
  2. Electropolishing
  3. Boil-Off Dead Rinse – Removes the drag-out electrolyte from the workpiece and reduces electrolyte waste
  4. Nitric Acid Neutralization
  5. Final Rinse.

Chemical Etch Wet Bench / Industrial Fume Hood

Chemical Etch Wet Bench / Industrial Fume Hood

Common Applications for Industrial Fume Hoods

  • Medical device stent polishing and deburring of stainless steel and cobalt chrome
  • Industrial, aerospace and medical device stainless steel passivation per ASTM A967
  • Printed circuit board and silicon semiconductor photoresist stripping using chemistry like ACT970 etch residue remover and others

Common Configurations

Since fume hoods are made from highly customizable materials like polypropylene and PVDF, as well as Teflon® / PFA, and ECTFE (HALAR®), Best Technology is able to easily build a fume hood to fit customer-specific wet chemical process and lab requirements.

Semi-Automated Inline Citric Passivation Solution with Data Tracking

For one medical device manufacturer, the design of a citric passivation solution faced two major challenges: The manufacturing process required performing a water-break test after cleaning parts, before proceeding to passivation. This meant that they could not use a fully automated passivation solution. The system had to have data tracking for quality control purposes. Semi-Automated […]
