Fume Hoods for Wet Chemical and Fume Processing
Our industrial fume hoods are used in various applications including laboratory chemical research to full scale manufacturing of wet chemical processes like electropolishing, passivation, part etching, semiconductor wafer processing. Industrial fume hoods typical construction materials depend on the chemical handling properties required for the application but commonly include: polypropylene, stainless steel, PVDF, Teflon® / PFA, and ECTFE (HALAR®) 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.
Rear tank venting exhausted from top of system, with integrated rectifiers for electropolishing and pumps for electrolyte circulation
Rear tank venting on 2 tanks and fresh water rinse 3rd tank
Large Integrated PVDF tanks with water, air and nitrogen guns and magnehelic for ensuring proper ventilation requirements.
Common Applications for Industrial Fume Hoods
- Medical device stent polishing / 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
- Medical device electropolishing of titanium (Ti) and nickel titanium (nitinol) which require exhausting in a fume hood
Since the chemical fume hoods are often made for custom applications and constructed from highly customizable materials like polypropylene, stainless steel, PVDF as well as Teflon®, PFA, and ECTFE (HALAR®), Best Technology is able to easily build a lab fume hood to fit specific wet processing chemical requirements.
