A cleanroom is an environment that features a controlled level of chemical vapors, aerosol particles, airborne microbes, dust, and other environmental pollutants. Careful consideration for everything down to lab furniture is required when outfitting a cleanroom environment. Cleanroom laboratory seating allows workers to remain productive while seated. Lab chairs enable research, project work, and document preparation.
Unique Aspects of a Cleanroom
Cleanrooms range in size from very small to quite large. Some represent entire facilities, requiring all workers to wear protective clothing and use special equipment. Outside air is filtered before it enters the room, removing dust, and the inside air is subject to constant recirculation to remove contaminants generated within the cleanroom.
Though a cleanroom is not sterile, equipment used in this environment is designed to create minimal air contamination. Pencils and paper are replaced with items that create fewer environmental pollutants. Furniture, including lab chairs, has features that create a minimum of particles. Laboratory seating and other cleanroom furniture are also easy to clean. A particle counter is used to test particle levels, ensuring that they remain within a certain range.
Features of Cleanroom Seating
Cleanroom chairs are offered in different classes, designed to be equivalent to different ISO Class standards. For example, a class 1000 chair from RDM Industrial Products features chrome-plated metal parts, a task control ergonomic mechanism, vinyl upholstery recommended for cleanrooms, and vinyl seat underwrap featuring filtered exhaust ports. A class 100 chair eliminates the seat underwrap and adds Grade 2 vinyl upholstery and a Class 100 filtration system.
Standard features of these lab chairs include an upholstered seat, painted metal parts, backrest with tilt and lumbar support, adjustable height, a foot ring, and nickel plated glides. Armrests, articulating seat control, and casters are a few options. By selecting the proper class of cleanroom laboratory seating and adding desired features, comfort is achieved without presenting environmental risk.
