Comfort is important to contamination-control professionals confined to the cleanroom for extended periods. Equally important, however, is ensuring that cleanroom furniture conform to cleanliness requirements, so as not to jeopardize the integrity of the critical environment. Here is a selection of cleanroom furniture that does just that.
Ergonomic cleanroom/ESD-control chair
 |
BioFit® Engineered Products offers its EEP Series ergonomic upholstered chairs for comfort, support and durability in Class 10 [ISO Class 4] combination cleanroom/static control applications. The EEP Class 10 combination chairs are engineered to support a balanced work posture and to resist wear. The backrest is 15.5 inches wide by 14.5 inches high and has a lumbar curve to support the lower back. The seat features four-way contouring and a waterfall front for proper weight distribution. The backrest is equipped with a plastic protective panel, and the seat’s molded-foam cushioning has an internal seat-board bumper guard for added durability. BioFit’s EEP Series offers the adjustability and seat-height adjustment ranges for comfortable work at desk-to-bench heights. Height- and width-adjustable armrests are an option for added support. EEP Class 10 combination chairs employ BioFit’s Microtech filtration system: The polypropylene filter system allows the seat to conform to body shape while achieving Class 10 protection levels by trapping particles 0.10 micron and larger. The EEP combination seating protects against static charges by providing 100 percent continuity. Static drain routes are located around parts that are insulated in standard models. The chairs have chrome-plated metal parts, ESD vinyl for static dissipation, conductive casters or glides, and a drag chain for grounding to an ESD-control floor or mat. The chairs have a five-legged, fully polished, cast-aluminum base with 27-inch leg spread.
