Air Hood

Shown is a manually-attended, clean air hood station capable of providing a class 50, or better, clean air environment using a class 100 prefiltered clean air supply to a one inch thick HEPA filter 1 tilted on a 12 degree angle over a process work area.

The hood includes side frames bolted together, with covers 2 designed to be standard for all hood sizes, an air plenum for each length of hood, and two foot modular process control consoles 3 which are bolted on top of the plenum in the number of units required.

The self-contained plenum is bolted to the side frames, and is designed to accept 1'' x 24'' x 24'' HEPA filters which can be installed and removed from the front of the hood. The hood is designed to accept the filters at a 12 degree angle from the vertical to provide an air curtain in front of the process area. A PLEXIGLAS* air shield 4 to control the amount and direction of air flow in front of the work surface is mounted in front of the plenum and parallel to the air flow. * Trademark of Rohm and Haas Co.
