A fully flat door with contours minimized to the extreme.
GOOD DESIGN Award 2019 Winning Product! Clears JIS airtightness performance A-4 grade. Flush doors typically have minimal protrusions, but when hardware such as hinges, door checks, or peepholes are added, they can create uneven surfaces where dust can accumulate. In a cleanroom, even slight protrusions can disrupt airflow. The full flat door minimizes these irregularities as much as possible, maintaining a clean environment that is easy to clean while being mindful of GMP standards. The double-glazed peephole*1 is frameless and flat, and the hinges and door checks are integrated into the door itself*2, ensuring a flat surface. Additionally, the standard aluminum outer frame has the same thickness as the door itself, making it flat. Only the handle for opening and the lock for securing*3 are exposed; everything else from the frame to the door is truly “full flat.” This door retains the lightweight opening and closing feature and excellent airtightness characteristic of cleanroom doors while pursuing ease of cleaning and prevention of airflow disruption, representing the ultimate form of cleanroom doors. *1 The window is optional. *2 It can also be changed to an auto hinge as an option (it will be exposed). *3 The lock is optional.

basic information
The "full flat door," which maintains the lightweight opening and closing and excellent airtightness characteristic of Sanwaise's cleanroom doors, has been designed to pursue ease of cleaning and prevention of airflow disruption, making it the ultimate form of cleanroom doors. ✔ It is a full flat door that eliminates the recesses in the viewing window area, protrusions of the window frame and hinges, and most protrusions except for the handle and key insertion point. ✔ With no unnecessary protrusions, dust, dirt, and powder are less likely to accumulate, making cleaning easy. ✔ The frame has the same depth dimensions as the door, so it does not protrude beyond the door. ✔ The interior of the door is made of aluminum profiles and insulation material, and the surface is made of 0.4 mm thin steel plate, making it ultra-lightweight. ✔ The frame and door are tightly sealed with gaskets, ensuring airtightness. *Note 1: There are limitations on the dimensions that can be manufactured if using hinge concealment without protrusions. *Note 2: This applies when the outer frame is made of aluminum extrusions. It is also possible to manufacture with steel or stainless steel frames to match the wall thickness, but in that case, the frame and door will not be flat.
