ANNEX 1
GMP Environment. Regulation for cleanrooms and cleanroom classifications.
Airlock furniture
Special furniture for hygiene-sensitive staff airlocks. They ensure strict separation between clean and unclean areas and maintain required hygiene standards.
Black-White separation
Spatial or functional separation between contaminated (“black”) and clean (“white”) areas to prevent cross-contamination.
Chemical resistance
Resistance of a material to disinfectants, cleaning agents, or laboratory chemicals.
Cleanability
Property of furniture, surfaces, and constructions that allows efficient and reproducible cleaning.
Cleanroom classes
These indicate how clean the air in a cleanroom is. The lower the ISO number, the cleaner the area. The same applies in GMP environments, where Grade A is cleaner than Grade D.
Cleanroom furniture
Furniture specifically designed for controlled environments. It supports hygienic processes, prevents particle accumulation, and is optimized for regular cleaning and disinfection.
Cleanroom-compatible design
Design of furniture focused on hygiene, cleanability, and process safety.
Cleanrooms
Controlled environment
Contamination
Unwanted pollution of materials, air, or surfaces by germs or substances.
Contamination control
Measures to prevent contamination in sensitive production or laboratory environments.
Dead spaces
Hard-to-reach areas in constructions where dirt, particles, or moisture can accumulate. Should be avoided in GMP environments.
Decontamination
Removal or reduction of microorganisms, particles, or chemical residues.
GMP
Good Manufacturing Practice. International quality guidelines for manufacturing, especially in pharmaceuticals, biotechnology, and medical technology. GMP ensures that processes are controlled and reproducible.
GMP grades A–D
Cleanliness classes in GMP-regulated production environments defining requirements for environment, personnel flow, and product protection.
Glass
Glass - We exclusively use high-quality ESG-H (heat-soaked toughened safety glass) for our products.
HPL
(High Pressure Laminate) A highly compressed laminate with a closed, durable surface. HPL is used in cleanroom and laboratory environments because it is moisture-resistant, hygienic, and easy to clean.
ISO 14644
International standard for classifying cleanrooms based on particle concentration. ISO classes range from ISO 1 (high-end research) to ISO 9 (normal ambient air). The lower the number, the higher the cleanliness requirement.
Low-particle design
Furniture design with smooth surfaces, minimized joints, and easy accessibility to reduce particle generation.
Material airlock
Area for the controlled transfer of materials, tools, or production equipment between different cleanliness classes.
Material flow
Planned movement of products, raw materials, or auxiliary materials through hygienic production areas.
Personnel flow
Controlled movement of employees through changing rooms, airlocks, and cleanrooms.
Rear ventilation
Connection of furniture to room air circulation systems.
Sit-over benches
Special benches, also called step-over benches, used in cleanroom environments.
Staff airlock
A defined transition area between different hygiene zones. Employees change clothing, shoes, or personal protective equipment here to avoid contamination.
Stainless steel
A particularly pure, high-quality, corrosion-resistant steel. It is durable, stable, hygienic, and visually high-end.
Street shoe airlock
Ensures that germs, dust, and contaminants do not enter clean areas.
Top panels
Ceiling cladding made of HPL. Closed systems from the top of the furniture to the underside of the ceiling.
Transponder technology
The transponder receives a radio signal and automatically responds to it. Manual operation is not required.
Validatable
A product or system designed so that its function, cleanability, and suitability can be tested, documented, and consistently verified.
Wet room doors
Doors specifically designed for rooms with high humidity or direct water exposure.
