Body box

The cabin for particle measurements under clean room conditions

The Bodybox was developed to be able to carry out holistic measurements on clothing, people or individual devices. It makes it possible to explicitly count the particles emitted by the test object or the device and to be able to make a statement about its suitability for clean rooms.

How a body box works

The two fan filter modules integrated in the ceiling ensure the clean air supply inside the cabin. The almost complete filter coverage of the ceiling creates a low-turbulence vertical displacement flow in the test room with an air purity of class 1 according to DIN EN ISO 146441.
Loaded with the particles emitted by the test object, the air flows through the grating floor of the chamber. A particle counter can be used to measure the number and size of airborne particles at a defined narrowing of the return flow channel. The lock adjacent to the test room serves as a return flow area to the filter units. The resulting rotating filtration of the same air mass leads to a constantly high level of cleanliness in the test room.

Advantages of a body box 

With targeted measurements using the holistic method, the real particle contamination by humans in a clean air environment can be proven in the body box. The air circulation principle ensures a long service life for the filter medium.

Plug connections enable quick assembly and disassembly of the chamber. This makes it suitable for short-term use, for example for external measurement and testing tasks.

Areas of application

The body box can be used in any environment. An important area of ​​application is the examination of complete devices or assemblies for their particle emissions per unit of time. Thanks to the body box, disruptive influences from the environment, such as cross-flowing particle sources, can be minimized. Long-term measurements and measurements on devices with moving parts are possible without any problems.

With the option to illustrate particle emission from a person with and without cleanroom clothing, it is also ideal for training purposes for cleanroom personnel. Basic theories can be explained here in a practical way.
