BioSafe^® Multi-Room Designs

Multi-room powder-coated BioSafe® Cleanroom

BioSafe^® panels function equally well as exterior and interior walls. Their modular design simplifies the engineering of multi-room facilities. The ceiling filtration system is likewise pre-engineered for optimal versatility, allowing rapid configuration of rooms to meet cleanliness standards from ISO 8 to ISO 3 (Class 100,000 to Class 10).

Such features as remote fan/filter control modules and adjustable air return registers allow cascading cleanliness levels and air pressures in multi-room applications. This versatility allows a room to be upgraded to more stringent cleanliness level if required, either by adding additional Fan/Filter Units (FFUs) or ramping up operating speed of existing FFUs from a remote touchscreen control. Rooms with less critical cleanliness requirements operate with fewer FFUs, reducing energy and maintenance expenses. Ceiling-mounted high-volume air handlers can be used to draw air from a production room into a ceiling plenum chamber, creating negative air pressure often required in BSL-2 facilities.

Pass-through chambers also promote clean transfer of materials in and out of the cleanroom. Pass-throughs can be small, wall-mount chambers with interlocked doors, or larger chambers that allow transfer or carts or bulky instruments.

Gowning Room (Change Room)

Typically, a gowning room is designed as a U-shape area, with placement of gowning benches and other furniture reinforcing the proper garmenting protocol to prevent violation of gloves or garments by contaminants that could be carried into the cleanroom (see garmenting protocol). Cleanliness levels in a gowning room are typically not as high as in cleanroom production areas. Placement of an Air Shower between the gowning room and cleanroom helps remove surface contaminants from garbed personnel and reduce the cleanroom particle load.

Entrance corridor links all production rooms and provides a buffer zone between controlled production rooms and uncontrolled warehouse space		Exit corridor of a 304 stainless steel BioSafe® Cleanroom also serves as an equipment service corridor

Entrance and Exit Corridors

Entrance corridors provide an air pressure buffer between the clean rooms and the external environment. Typically, personnel enter this corridor from the gowning room, often by passing through an air shower. Separate antechambers (air locks) link the corridor to each clean room, and adjustable air return registers allow air pressure balancing to maintain the proper differential air pressure between each controlled environment.

Exit corridors provide both a way for personnel to exit the cleanroom and a way to transfer large process equipment into controlled areas. Electrical service panels can also be mounted in the service corridor, allowing servicing of electrical components without breaching the cleanroom environment.
