Applied Physics · Precision technologies since 1992
Laboratories and manufacturing facilities often require extremely clean conditions for sensitive processes.
Building a complete cleanroom is expensive, time-consuming, and inflexible.
The Stand KOACH C-645-F and C-900-F address this issue by creating a localized ISO Class 1 clean environment anywhere in a room, without walls, ceilings, or permanent installation.
Manufactured by Koken Ltd. in Japan and distributed by Applied Physics USA, these portable systems provide semiconductor fabrication plants, pharmaceutical laboratories, and research facilities with a practical way to achieve the highest level of air cleanliness exactly where it is needed.
The Stand KOACH is an open, clean-air system consisting of two vertical units positioned facing each other. When placed on opposite sides of a worktable, they create a controlled, clean-air zone between them.
Unlike conventional clean benches that enclose the workspace, the Stand KOACH keeps the working area completely open. Operators can work freely from all sides, move large equipment in and out, and collaborate face-to-face.
Both the C-645-F and C-900-F models use advanced nanofiber filters called FERENA. These filters remove airborne particles as small as 0.1 micrometers, including many virus-sized particles, and provide ISO Class 1 cleanliness in less than two minutes.
The technology is simple and effective
Because the clean zone is created by air alone, there are no walls to block access or generate additional particle sources. Contaminants generated by hand movement or tools are carried out of the zone rather than trapped inside.
ISO Class 1 is the highest cleanliness rating defined by ISO 14644-1. It allows only a few particles larger than 0.1 μm per cubic meter.
The Stand KOACH reaches this level in less than two minutes and maintains it during normal work activities.
Operators can work from any angle. Large microscopes, wafer handlers, or process tools can be placed inside the clean zone without restriction.
Face-to-face collaboration is possible, which is difficult with conventional clean benches.
Both models roll on casters. A clean zone can be set up in minutes wherever it is needed, in a corner of a lab, next to a production line, or temporarily for a specific project.
When the work is finished, the units can be moved or stored.
Building a permanent ISO Class 1 cleanroom requires significant capital, construction time, and ongoing energy costs.
The Stand KOACH provides the same air quality in a much smaller footprint and at a fraction of the cost for localized needs.
Both models deliver the same ISO Class 1 performance. The main differences are size and the maximum distance between the two units.

These systems are designed for environments that require high cleanliness but cannot always justify a full cleanroom.
The Stand KOACH C-645-F and C-900-F give laboratories and manufacturers a practical way to achieve ISO Class 1 cleanliness exactly where it is needed.
By combining high-performance nanofiber filtration with an open, portable design, these systems remove the traditional trade-offs between cleanliness, access, and cost.
Whether you are protecting sensitive semiconductor wafers, preparing sterile pharmaceutical samples, or assembling precision components, the Stand KOACH delivers a controlled clean environment without the expense and rigidity of a full cleanroom.
For facilities that value flexibility and performance, it is a proven and efficient solution.
The system typically reaches ISO Class 1 cleanliness in less than two minutes after start-up.
Yes. The open design allows multiple people to work across the table without walls or barriers blocking access.
The nanofiber filter captures particles as small as 0.1 micrometers, which includes many virus-sized particles.
No permanent installation is required. Place the two units facing each other, plug them in, and turn them on. Casters make repositioning easy.
Select the C-645-F for compact workspaces or lighter equipment. Choose the C-900-F when you need a wider clean zone for larger tools or multiple operators working together.
