Pre-engineered, modular design cleanrooms are cost effective without the inconvenience of conventional “stick-built” construction.
Once Through Design
Once-Thru Design is also known as single pass. Ambient air is drawn into the SAM Fan Filter Units at ceiling level. The filtered air passes into the cleanrooms and is transferred out of the room through grilles at the bottom of the walls.

Legend Cleanroom Designs
Provides Controlled Environment: Legend Hardwall cleanroom Wall Panels and Components are engineered to provide a secure controlled environment within the cleanroom.
Non-Progressive Design: As needs change, Legend wall panel modular design offers the ability to relocate or expand the cleanroom in the future.
Special Sizes: Wall panels can be made in special sizes for entry areas, gowning rooms and air-locks, ensuring that the cleanroom pressure remains constant. Extra-high, legend wall panel systems can accommodate large equipment which can require ceilings higher than the standard eight feet.
Load Considerations: Three factors are considered when determining which wall system to use for load-bearing cleanrooms. The first factor is the amount of total weight on the cleanroom wall, the second factor is the span distance between all four of the cleanroom walls and the third factor is the height of your wall. Consult with Production Automation for detailed information about your cleanroom project.
Once Through Design: Ambient air is drawn into the SAM Fan Filter Unit at ceiling level. The filtered air passes into the cleanroom and is transferred out of the room through grilles at the bottom of the walls. Refer to figures 1 and 2.
Recirculating Design: Recirculating cleanrooms are ideal when temperature or humidity control is required. Refer to figure 3.
Legend Cleanroom Classes
How are Cleanroom Standards Determined?
The number and size of particles allowed in the room determines the classification of air cleanliness.
Guidelines for selecting filters: PAC can help make the calculations necessary to achieve the desired ISO or U.S. Federal Standard 209 Class. The correct quantity of HEPA or ULPA grade filters will be selected using air changes per hour as the most effective method for meeting class requirements.
Installation, Testing and Certification: A network of authorized installers enables Cleanrooms International to offer complete installation services or testing and certification, which Production Automation can help arrange if needed.
Accelerated Depreciation: Conventional construction becomes a permanent part of the host building and requires the straight-line method of depreciation over as long as 39 years, depending upon current law. A shorter depreciation life for the modular cleanroom results in a quicker write-off and faster payback for the cost of the room.
Modular cleanrooms built from Legend Cleanroom Systems can qualify for accelerated depreciation vs. conventional construction. Consult with your accountant to determine if favorable depreciation rules apply to your purchase of a Legend Cleanroom System.
