Ideal for clean rooms

The CR series is suitable for contamination-free use in highly sensitive manufacturing processes. The air filtration systems were made for being used in laboratories or clean rooms. The filter and extraction systems are compact and easy to integrate everywhere. They provide functionality and safety when using low-contamination materials, both in clean room cabins (ISO 14644) and in clean rooms (VDA 19 or ISO 16232). They meet the increasing product and quality requirements due to the contamination-free filter change up to ISO Class 5 (DIN EN ISO 14646-1).

Features and functions

Modular attachment, flexible usage and comfortable handling

Kontaminationsfreier Filterwechsel

Contamination-free filter change

The filter cartridges contain the suction pipe and the extendible protective tubing. When the pipe is disconnected, the protective tubing can be extended to cover the point of disconnection. That shields the filter cartridges' air inlet from dust. After sealing the protective plastic film, the filter can be removed without contamination.

  • Different filter cartridges

  • Open air inlet tied or welded by a protective hose

  • Contamination-free filter removal

  • Removal of the filter by prior sealing of the plastic protective film 

Absaugung von Gefahrstoffen

Suitable against Hazardous Substances

Entirely meets all requirements for a safe extraction.

  • Extract all hazardous materials, mixtures/compositions or products completely and safely.

  • No toxic gases or fumes can leak the system.

  • These systems can extract even easily flammable or explosive materials completely.

  • The filters keep the extracted particles safely, so they cannot leave into the ambient air.


Captures harmful particles

Pollutants have no chance.

  • Low-contamination dust disposal

  • Molecular sieve against gaseous pollutants

  • Pipes /flexible hose/extraction arm

  • Air return or exhaust air duct

More features

Energy saving

Particularly quiet and environmentally friendly

  • Low energy costs, environment-friendly

  • Noise-reducing blower

TBH extraction systems for your processes

Clean Room

Air filtration is especially important in clean rooms as even small amounts of particles in the air can be already too many. The contamination is specified by the number of particles per cubic meter at a specified particle size. In practically every industry particles can affect manufacturing processes.  Hygiene regulations are strict in clean rooms e.g. in pharmaceutical industry. 


Manufacturers of electronic products work with small or tiny elements. Highly toxic materials such as arsenic or phosphorus are often used to modify the properties of semiconducting substances. Solvents on the microchips are used to remove contaminants that pose a burden on the environment and on employees. Therefore, fume extraction is very important in electronics production. TBH GmbH offers clean air solutions for the electronics industry. 

Medical Applications

Medical treatments using lasers let arise harmful laser fume particles. Physicians and patients should not inhale them, as they are dangerous to their health. Air filtration is the only solution to clean the air properly. Extracting and filtration systems reduce the infection risks in medical practices and ensure a contamination-free environment.
