FAQs About CGMP Cleanrooms Q: What is a GMP cleanroom? A: A GMP cleanroom is designed to comply with all FDA requirements for FDA Good Manufacturing Practice (GMP).  GMP requirements for cleanroom manufacturing facilities include cleanroom classification, controlled environment (temperature and sometimes humidity), viable and non-viable particle counts, sterility, and others. Q: What is a CGMP cleanroom? A: A GMP cleanroom is designed to comply with all FDA requirements for FDA Current Good Manufacturing Practice (CGMP). CGMP companies look for improvements to GMP cleanrooms to justify the CGMP label. Features commonly include:  interlocks, coving, monitoring systems,  and static dissipative heat welded vinyl flooring. Q: What products require a CGMP cleanroom? A: FDA CGMP typically applies to pharmaceutical products. Q: What is EU annex GMP annex 1 for cleanrooms? A: This is European regulations for manufacturing pharmaceutical products. It differs from USA FDA CGMP. Q: What are requirements for equipment going into CGMP cleanrooms? A: The equipment must not have a negative impact on product quality. The equipment must be easy to clean. The equipment must comply with the applicable technical regulations. The equipment must be suitable for its purpose. Q: What is FDA validation and how is it part of a cGMP cleanroom? A: FDA validation is the FDA approval process for new pharmaceutical products/drugs. Among items included is drug development, testing, manufacturing, training, equipment, facilities, QA program, and documentation. Q: Do I need to do continuous particle testing in my cleanroom? A: Continuous cleanroom particle counting within cGMP is only a requirement in Grade B and Grade A environments. Both are ISO-5 at rest.  Grade A is high risk operations like filling, open ampoules, and aseptic preparation. Grade B is background area for grade A and has less  stringent operational particle requirements. Q: What is the difference between a clean room and a sterile room? A: A clean room uses HEPA filtration to remove particles from the air. A sterile room is a clean room that has been optimized to remove live organisms such as bacteria, viruses, mold, fungi, etc. via both HEPA filtration, chemical cleaning and radiation treatment. Clean rooms measure non viable particles with laser particle counters. Sterile rooms measure viable particles via settling plates etc. From the FDA website: “The CGMP regulations for drugs contain minimum requirements for the methods, facilities, and controls used in manufacturing, processing, and packing of a drug product. The regulations make sure that a product is safe for use, and that it has the ingredients and strength it claims to have. The approval process for new and generic drug marketing applications includes a review of the manufacturer's compliance with the CGMPs. FDA assessors and investigators determine whether the firm has the necessary facilities, equipment, and ability to manufacture the drug it intends to market.” For cleanrooms, the GMP requirements for manufacturing facilities include cleanroom classification, controlled environment (temperature and sometimes humidity), viable and non-viable particle counts, sterility, and others. Typical GMP Cleanrooms: FRP cleanroom walls for chemical resistance (for cleaning with strong chemicals) Heat welded cleanroom vinyl floors with integral cove ISO-8 or better cleanroom classification Gown rooms Classified material pass thru rooms Comfort cooling (in more demanding cases temperature and humidity control) Air pressure monitoring (cleanroom Magnehelic gauges) Chart recorders were often used to record temperature and humidity. Regularly scheduled replacement of cleanroom filtration RSR Room Side Replaceable HEPA fan filter units. With the move to FDA mandates, CGMP companies looked for improvements to GMP cleanrooms to justify the CGMP label. Some additions were: Door interlocks Coved cleanroom corners Coved cleanroom ceiling wall junction Digital monitoring systems for temperature, humidity and air pressure with alarm and data archiving Static dissipative heat welded vinyl flooring Continuous particle monitoring systems (non-viable) ### Cleanroom News Stay up to date with the latest cleanroom news, trends, and innovations from American Cleanroom Systems.

For more than 40 years, American Cleanroom Systems has provided premium quality modular cleanrooms and customer service. American Cleanroom Systems provides modular and turnkey cleanroom solutions but does not sell cleanroom supplies or equipment. For reference, common cleanroom supplies include garments such as bunny suits, hoods, gloves, masks, and booties, as well as cleaning tools like tacky mats, tex wipes, and mops used to maintain contamination control. Typical cleanroom equipment includes HEPA vacuums, particle counters, UV lamps, de-ionizers, and stainless-steel furniture. Cleanrooms are essential in industries such as pharmaceutical, medical device, food processing, electronics, manufacturing, and research & development. As a full-service manufacturer, American Cleanroom Systems designs and installs modular, hybrid, softwall, pharmaceutical, and static dissipative cleanrooms, among many other types. Compared to standard construction, modular cleanrooms can be completed in 9–14 weeks, roughly 50% faster than traditional builds that often take over 30 weeks with permitting. ### Pharmaceutical Cleanrooms Pharmaceutical cleanrooms are strictly regulated by the FDA in the U.S. and the EMA in Europe, and must comply with CGMP (Current Good Manufacturing Practice) standards. CGMP focuses on the “5 P’s” of quality—people, premises, processes, products, and procedures—to ensure safety and consistency in pharmaceutical production. American Cleanroom Systems designs and manufactures modular pharmaceutical cleanrooms that meet FDA and CGMP validation requirements. Typical pharmaceutical cleanroom features include FRP modular walls, HEPA fan filter units, FRP ceilings, heat-welded vinyl floors, interlocked gown and transfer rooms, and temperature/humidity control. These cleanrooms range from Class 100/ISO 5 filling rooms to lower-class formulation and support areas. Easy modification, fast delivery, and proven materials make American Cleanroom Systems a trusted provider for pharmaceutical companies such as AbbVie, Allergan, Baxter, Bausch & Lomb, Johnson & Johnson, Roche Diagnostics, and Regeneron Pharmaceuticals. ### Hybrid Cleanroom ### Cleanroom Air Flow ### Certification RFQ Form ### Mask Manufacturing Cleanrooms ### Home - Revise April 8 ### Modular Cleanroom Manufacturing in Arizona Cleanroom Design & Manufacturing American Cleanrooms Systems is an Arizona Licensed General Contractor Specializing in Cleanrooms   American Cleanroom Systems is a certified team of experts, that has been specializing in the manufacturing and installation of quality class 100-100k/ ISO5-8 modular cleanrooms since 1976.

The fibres are typically composed of fiberglass and possess diameters between 0.5 and 2.0 micrometers. Key factors affecting function are fibre diameter, filter thickness, and face velocity. The air space between HEPA filter fibres is much greater than 0.3 μm. The common assumption that a HEPA filter acts like a sieve where particles smaller than the largest opening can pass through is incorrect. Unlike membrane filters at this pore size, where particles as wide as the largest opening or distance between fibres cannot pass in between them at all, HEPA filters are designed to target much smaller pollutants and particles.: HEPA filters, as defined by the DOE standard adopted by most American industries, remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. The filter's minimal resistance to airflow, or pressure drop, is usually specified around 300 Pa at its nominal flow rate. Lastly, it is important to note that HEPA filters are designed to arrest very fine particles effectively, but they do not filter out gasses and odor molecules. Circumstances requiring filtration of volatile organic compounds, chemical vapors, cigarette, pet, and/or flatulence odors call for the use of an activated carbon (charcoal) filter instead of or in addition to a HEPA filter.   ULPA filters  ULPA is an acronym for "Ultra Low Penetration Air (filter)" An ULPA filter can remove from the air at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a size of 100 nanometres (0.1 µm) or larger.   HEPA fan filter unit (FFU) A HEPA FFU is a type of air filtering equipment. It is used to supply purified air to cleanrooms or microenvironments by filtering out harmful airborne particles from recirculating air. The units are installed within the system's ceiling grid as part of a negative pressure plenum. They consist of their own pre-filter, HEPA filter and fan.   Pass thru Pass Thrus are used as a means of moving parts and/or materials from a non-controlled environment to a clean room environment. There are both wall mounted pass thru and floor mounted pass Floor mounted pass thrus are typically used for rolling carts. Pass thrus typically have mechanically interlocked doors to prevent particulates from entering the cleanroom when loading or unloading. Some pass thrus have their own HEPA FFU for additional cleanliness.   Air shower Air Showers are used to remove contaminate off personnel and equipment as they enter a clean environment or exit a contaminated environment. Air showers also create a protective barrier between the clean and contaminated areas. Features include HEPA filters on air flow, interlocked doors to prevent particulates from entering cleanroom. They also serve as air locks.   Cleanroom Classifications Class 100 – less than 100 particles per cubic foot and 300-480 air changes per hour Class 1000 – less then 1000 particles per cubic foot and 180 air changes per hour Class 10000 – less then 10,000 particles per cubic foot 60 air changes per hour Class 100000 – less than 100,000 particles per cubic foot 20 air changes per hour   Air lock Airlock is composed of two doors that are electrically interlocked in such a way that the two cannot be opened simultaneously. Airlocks are used in a variety of situations but in essence they are there to control the unwanted passage from one area to another. Airlocks may be used to control the entry of personnel to a secure area such as a cleanroom, where dust or small particles may be a problem. Similarly if a constant temperature must be maintained then an airlock can be invaluable in reducing temperature fluctuations when doors are opened. Sometimes gowning rooms are used as air locks without the interlocked doors. The purpose remains the same – prevent particulates or non controlled air to enter the cleanroom. However the gowning room relies on procedure or light indicators to make sure.   Magnahelic gauge Magnahelic gauge are used in cleanrooms to measure the differential pressure between the cleanroom and ambient. Cleanrooms are typically positive pressure to ambient so particles will not enter the room.   Laminar air flow In laminar air flow the air tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards. There are no cross-currents perpendicular to the direction of flow, nor eddies or swirls of air In laminar flow, the motion of the particles of the air is very orderly with all particles moving in straight lines. Well designed cleanrooms use ceiling mounted HEPA fan filter units and low wall air returns to achieve laminar air flow from ceiling to floor. This means air borne particulates are driven downward away from critical process areas and out of cleanroom instead of moving around cleanroom in turbulent air flow. This type of cleanroom is more effective in removing particules.   Cleanroom Gowns Workers typically wear non particulating cleanroom gowns and booties when working in cleanroom. They are either laundered by cleanroom laundry service or disposable. The level of gowning depends upon class of cleanroom and processes being performed. If facial hair is present than a beard/mustache guard is also worn. In lower class cleanroom (class 100k) sometimes just lab jacket, hair net and booties are worn.   Hardwall cleanrooms Hard wall cleanroom give advantages of softwall cleanrooms because Most common type of cleanroom Cleanable surfaces Can control temperature and humidity Can maintain positive air pressure Can have gowning rooms, air lock More durable   Softwall cleanroom Lower cost Utilizes existing air conditioning Difficult to accommodate plumbing, gases, heat load, exhaust air Limitation on how big Cannot wipe down / clean Often portable (if small size)   ### Class 10,000 Cleanroom What Is a Class 10,000 Cleanroom? Cleanrooms are classified according to the number and size of particles permitted per volume of air. Large numbers like "class 100" or "class 1000" refer to FED-STD-209E, and denote the number of particles of size 0.5 µm or larger permitted per cubic foot of air. Class 10,000 would have <10,000 particles/cubic foot. Minimum of 45 to 60 air changes per hour. Various Class 10,000 Applications: Pharmacy compounding roomsSemiconductor non photolithography (bonding, metal deposition, testing)Pharmaceutical manufacturingAerospace manufacturing Typical Class 10,000 Cleanrooms Utilize: Gowning room /air locksProduct pass thru’sHeat welded vinyl or epoxy floorsAir conditioning for temperature controlHEPA fan filter unitsSealed cleanroom lightingMagnahelic gauge for room air pressure monitoringWorkers typically garb up in non particulating cleanroom bunny suits, booties and hoods.Some applications use air showers to enter.Sticky mats at entrance and exitStainless steel benchGown racksStainless steel - hand free sinks Design: Negative pressure plenumCeiling mounted HEPA fan filter units and low wall air returns for laminar air flowCleanable hard walls Softwall Class 10,000 option: Clear vinyl wallsStrip curtain for entranceSteel frameCeiling mounted HEPA FFU’sCeiling mounted lightingSometimes mounted on casters Softwall Class 10,000 Limitations: No temperature controlNo measurable positive pressureCannot clean walls Class 10,000 Softwall Typical Applications: Inside Class 100k roomInside warehouseWeighing product during packagingInspection stationsTemporary cleanroom ### Cleanroom Testing and Certification Cleanrooms are designed to control airborne particulate and environmental conditions.
