Vertical Laminar Flow Hardwall Cleanroom for Laboratory

CleanroomSupply offers a complete selection of portable and modular cleanrooms in both hardwall or softwall configurations. These modular cleanrooms are available from class 10 (ISO 4) to class 100,000 (ISO 8). Recirculating air flow systems can be provided for climate control.

Modular Design

The modular design of the cleanrooms provides for an easy cleanroom installation as well as the flexibility of quickly being able to expand or relocate the room. The hardwall or softwall cleanroom designs can offer free spans of up to 32 feet.

ISO Class 5, (Class 100, FED STD 209E)

Despite the fact that it’s ISO class 5, many people in the industry call this level Class 100. This is due to the FED STD 209 cleanroom classification of measurement, commonly known throughout cleanroom circles. With these particular clean rooms, particles that are smaller than 0.1 µm start at 100,000, and for less than 0.2 µm, measure at 23,700. These cleanrooms also allow for bigger particles than the previous two classes, allowing 832 particles that are less that 1 µm in size.

SO Class 6, (Class 1,000 FED STD 209E)

Commonly referred to as Class 1000 by the FED STD 209 standards, this class allows up to 1,000,000 particles that are smaller than 0.1 µm. It’s also similar to class 5., in that it allows for larger particles. In fact, up to 8,320 particles per cubic meter are allowed, as long as they are smaller than 1 µm.

SO Class 6, (Class 1,000 FED STD 209E)

Commonly referred to as Class 1000 by the FED STD 209 standards, this class allows up to 1,000,000 particles that are smaller than 0.1 µm. It’s also similar to class 5., in that it allows for larger particles. In fact, up to 8,320 particles per cubic meter are allowed, as long as they are smaller than 1 µm.

ISO Class 7, (Class 10,000 FED STD 209E)

This particular class is often called class 10,000, and for particles smaller than 0.5 µm, there can be up to 352,000 cubic meters. For larger particles that still fall under 1.0 µm, there can be up to 8,320 particles. In addition, particles in this class can be up to 5 µm but are limited to 2,930 particles per square cubic meter.

In addition, ISO Class 7 is typically classified as Grade C. This means that at rest, 352,000 particles smaller than 0.5 µm can be present at any given time. During operation, this number multiplies to 3,500,000 particles. Most of these are generated due to the use of equipment and movement that occur.

ISO Class 8, (Class 100,000 FED STD 209E)

Also known as Class 100,000, ISO class 8 provides an environment that is slightly different than room air, allowing 3,520,000 particles that are smaller than 0.5 µm. For particles that are less than 5 µm, the room can have upwards of 29,300.

ISO Class 8 is also commonly associated with clean rooms that are Grade D. At rest, they are limited to less than 3,500,000 particles that are smaller than 0.5. During operation, this number isn’t specified, but allows for the largest grade differential.
