Machine Enclosure Hoods

Many factories and production plants utilize large machinery for their manufacturing process. These machines may use heat, cutting, blasting, mists, coolants, and routing to create materials or finished goods. These processes emit particulate and odor into the air that not only pose respiratory hazards to workers, but can accumulate on floors and surfaces causing slip hazards. An economical way to contain these contaminants is to enclose the machines within a negative-pressure hood.

Enclosing a large piece of machinery doesn’t have to break your budget or require several says of installation. At Sentry Air Systems, we design economical, modular, and easy-to-assembly hooded enclosures that offer negative pressure air filtration to large machinery. Typical applications include plastic injection molding, vacuum plastic molding, lathes, routers, and other similar applications where oversized machinery produces airborne contaminants.

Walk-In Fume Hoods

In certain applications, the workpieces can be larger or cumbersome to work within small benchtop hoods and may not be practical to source capture through a standard fume extractor due to size. In these types of situations the walk-in concept allows the operator to isolate the application in a larger chamber without having to expose the entire environment. Typical applications include: solvent parts cleaning and other chemical fumes, light grinding, welding fume extraction, acid gas fume control, packing, powder processing, particulate containment, and a variety of other applications that involve fumes and dust.

These are ideal on manufacturing floors where a specific process is generating fumes or particulate and operators do not want to cross contaminate the other work areas. The concept of a walk-in hood also creates a mini “dirty-room” or sub-assembly room that is much cheaper, mobile, and easier to erect than a conventional room. The modularity of the walk-in hoods allows flexibility between ductless or ducted fume exhaust.
