Founded in 1968, PolyFab provides custom engineered plastic fabrications.

We work with many materials and specialize in clear plastics.

Some of the applications we have made include:

  • Large graduated cylinders
  • Architectural formed pieces
  • LEXAN® Tanks and waterbaths
  • Clear PVC and acrylic assemblies
  • Laboratory splash guards and custom trays for all industries
  • Plastic flooring and secondary containment basins
  • Custom PVC, CPVC, polypropylene and HDPE duct work
  • Fume hoods made from any weldable plastic material
  • Marine fresh, gray, and black water tanks
  • Custom polypro and HDPE tanks for chemical storage and treatment
  • Machined polyethylene fittings
  • Routed plastic and wood signs

Walk In Fume Hood

 

Reduction in the breathing zone concentration of an experimentally simulated pollutant, by factors ranging from 100 to 800, was observed with the device (called an airvest). With use of the airvest by the worker, the hood face velocity can be reduced, leading to substantial energy savings in conditioning of make up air in the building. The airvest works by elimination or ventilation of the eddy that develops in front of a worker when the worker stands in the open face of a fume hood. Normally this eddy draws some of the pollutant (commonly generated near and in front of the worker) towards the worker's breathing zone. Experiments sing a heated full-size mannequin were conducted with a full scale walk-in fume hood. Sulfur hexafluoride was used to simulate pollutant generation and exposure during a work situation. Flow visualization with smoke was also undertaken to evaluate the airvest qualitatively.
