D669 Cleanroom Door (Narrow Frame Version)

The D669 is a compact upgraded version developed by Victory Door based on the D668 standard cleanroom door, designed specifically for space-constrained installation environments. While fully inheriting the D668's high-seal silicone track system, self-resetting function, and rapid opening/closing performance, it achieves ultra-compact installation dimensions: only 368mm above the door opening, 188mm on each side, and 186mm of external clearance. This makes it ideal for complex site conditions such as low-ceiling factories, equipment-dense areas, renovation projects, and spaces with complex piping. Suitable for clean environments requiring positive or negative pressure control—including laboratories, food processing workshops, and electronics clean areas—the D669 provides an ideal isolation solution for spaces where standard cleanroom doors cannot be installed due to spatial limitations.
