WuJiang DeShengXin Purification Equipment Co.,LTD. Cleanroom Design Guidelines
1.Cleanroom Design Guidelines-cleanroom with air shower
Cleanroom airlock (also known as an
Cleanroom Airlocks or AnteRoom - This is a room
between the cleanroom and an un-rated or less clean area surrounding the
cleanroom or between two rooms of differing cleanliness class. The purpose of
the room is to maintain pressurization differentials between spaces of
different cleanliness class. An airlock can serve as a gowning area. Certain
airlocks may be designated as an equipment or material airlock and provide a space
to remove packaging materials and/or clean equipment or materials before they
are introduced into the cleanroom. Interlocks are recommended for airlock door
sets to prevent opening of both doors simultaneously.
For equipment airlocks,
an indicator light inside the cleanrooms in recommended to show when the
outside door is open.
2.cleanroom designed Guidelines- pass-through
cleanroom Pass-Throughs box- A pass-through airlock should be provided for the transfer of small articles from uncontrolled areas into the cleanroom or between areas of different cleanliness class. The pass-through box may include a speaking diaphragm, intercom, or telephone for communication when items are transferred, and interlocks to prevent both doors from being opened at the same time. A cart size pass-through installed at floor level can be used to facilitate movement of carts between clean areas.
3.Cleanroom Design Guidelines-Cleanroom windows
Cleanroom Windows are recommended in cleanrooms to facilitate supervision and for safety, unless prohibited by the facility protocol for security reasons. Cleanroom windows should be placed to permit viewing of operations in order to minimize the need for non-cleanroom personnel to enter the cleanroom.
The cleanroom Window should be impact resistant glass or acrylic, fully glazed, installed in a manner that eliminates or minimizes a ledge within the clean space. Double-glazing is frequently used to provide a flush surface on both sides of the wall containing the window. Windows may be included if there is a public relations requirement for visitors to view the operations. Speaking diaphragms of flush, wall mounted, intercom systems are recommended near all windows to facilitate communication with occupants of the cleanroom.
4.Cleanroom Design Guidelines-Gowning Rooms
Cleanroom Gowning Rooms should be designed to support the garment protocol established for the facility. A typical gowning room may have the following items:
a.Wall mounted coat rack for clean garment storage located at a height to prevent dragging on the floor.
b.Bench:A full-length mirror installed near the door for gowning self-inspection.
Storage for packaged garments
Bins for disposal of soiled garments.
Personal lockers and coat racks for the storage of notebooks, coats, and personal items should be located outside gowning room or in an antechamber separate from the clean room or in an antechamber adjacent to the clean gowning area. A common gowning room design has two areas divided by a bench. The "unclean" area is used to remove and store outer garments. Stepping over the bench, as the cleanroom footwear is being put on insures that the "clean" side of the gowning room will remain that way. Final donning of the cleanroom garb is then accomplished.
5.Cleanroom Design Guidelines-cleanroom inside warehouse location
Siting - A cleanroom that serves as part of a larger process line should be integrated into the line to facilitate movement of personnel and materials in and out of the room. A free-standing cleanroom may be located in any convenient site however certain conditions adjacent to the facility may degrade its performance. Vibration sources inside or near a cleanroom will encourage particle release within the room and under severe conditions may cause leaks in filters and ductwork. Heavy equipment including the HVAC systems components, pumps, house vacuum system, etc ought to be vibration isolated. Location of a cleanroom directly adjacent to heavy equipment or loading docks that see heavy truck traffic, and other sources of vibration, shock and noise may be problematic. The outdoor air intake for the cleanroom makeup air must be carefully located to prevent overloading of filters or entrance of contaminating gases that the filter will not remove. Cleanroom air intakes should not be located near loading docks, traffic lanes, or other areas where vehicles may drive through or idle. These intakes should not be located near the exhaust locations of other processing facilities. Use of gas phase filtration may be required if the quality of make-up air is not acceptable.
