Cleanliness Class

	Cleanliness Class:		The contamination control industry currently uses a government specification known as Federal Standard 209D to provide a qualified and standardized method for measuring how clean the air is in a cleanroom. Six classes have been established to designate cleanroom cleanliness. The class number refers to the maximum number of particles bigger than one-half of a micron that would be allowed in one cubic foot of cleanroom air. A Class 100 cleanroom, for example, would not contain more than 100 particles bigger than half a micron in a cubic foot of air.
	Your choices are...
	Class 1 (ISO 3)		A cleanroom where particle count is not to exceed a total of 1 particle, 5 microns or larger in size, in a cubic foot of air.
	Class 10 (ISO 4)		A cleanroom where particle count is not to exceed a total of 10 particles, 5 microns or larger in size, in a cubic foot of air.
	Class 100 (ISO 5)		Particle count not to exceed a total of 100 particles per cubic foot of a size 0.5 micron and larger.
	Class 1,000  (ISO 6)		A cleanroom where particle count is not to exceed a total of 1,000 particles, 5 microns or larger in size, in a cubic foot of air.
	Class 10,000 (ISO 7)		Particle count not to exceed a total of 10,000 particles per cubic foot of a size 0.5 micron and larger, or 65 particles per cubic foot of a size 5.0 micron and larger.
	Class 100,000 (ISO 8)		Particle count not to exceed a total of 100,000 particles per cubic foot of a size 0.5 micron and larger, or 700 particles per cubic foot of a size 5.0 micron and larger.
	Other		Other unlisted cleanliness class, examples include ISO 1, 2 and 9.

Features and Options

	Panel / Wall Material:
	Your choices are...
	Steel		A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Steel - Stainless		Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
	Acrylic		A thermoplastic with good weather resistance, shatter resistance, and optical clarity.
	Aluminum		A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Composite		A solid material comprised of two or more substances that have distinct properties. When merged, each substance retains its own characteristics while imparting the entire composition with beneficial properties. For example, a plastic material in which a fibrous framework is embedded for greater structural stability.
	Fabric		A cloth, or material that resembles cloth.
	Fiberglass (FRP)		Fiberglass reinforced panels.  Strong, durable, and impervious to many caustics and extreme temperatures; fiberglass fabrics are widely used in industry.
	Glass		Glass has optical, mechanical, and thermal properties and has been a major building component for centuries.
	Polycarbonate (PC)		Polycarbonate is an amorphous material with excellent impact strength, clarity, and optical properties. Polycarbonate has excellent mechanical properties, and can be molded to tight tolerances. However, solvents and petrochemicals corrode it, and its weather resistance is merely adequate. Brand Names include: Caliber® (Dow), Lexan® (GE), Makrofol® and Makrolon® (Bayer).
	Polyethylene Film (Shrink-wrap)		A very thin layer of polyethylene.  Polyethylene is a semi-crystalline (typically around 50%), whitish, semi-opaque commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water.
	PVC		Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).
	Vinyl		Vinyl exhibits good flexibility and chemical resistance; it is used in many medical and chemical applications.
	Other		Unlisted, specialized, or proprietary material.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	ESD Control:		The cleanroom has measures to control the rapid, spontaneous and usually uncontrolled transfer of an electrical charge between two conductors induced by a strong electrostatic field.
	Your choices are...
	Static Dissipative		The panels of the cleanroom are less susceptible to triboelectric charging.
	Conductive Panels		The panels of the cleanroom are coated with a conductive epoxy or paint.
	Low Outgassing		The panels of the cleanroom outgas low amounts of particles.

	Air Shower?		Chambers located between the cleanroom and an outside environment that remove particulate contamination from cleanroom garments as personnel pass through. The chambers may include HEPA filters, interlocking doors, a recirculating air system, and air nozzles in various patterns through which filtered air is blown onto the personnel in the shower. The air is moved over the worker, removing particulate contamination from the worker's garments.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Product / Tool Pass Through?		Openings in walls with two doors through which materials and objects are passed. Pass through doors interlock so that one door always is closed while the other is open.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Gowning Area?		Area designed to be used for dressing into cleanroom garments.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
