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.
