Air filters for harmful gases & odors

Molecular Contamination Control

Camfil Molecular Contamination Control (MCC) operates globally in North America, Europe, the Middle East and Asia. The MCC division delivers molecular filtration solutions in light processes, industrial applications, cleanrooms and large installations concerned with indoor air quality, such as airports.

You’ve probably heard of sulphur dioxide, hydrogen sulphide, nitrogen dioxide, ozone, kerosene, formaldehyde and ammonia. How about polyaromatic hydrocarbons, volatile organic compounds (VOC), benzene, isocyanates and siloxanes? These are just a few examples of chemicals present in gas form in the atmosphere, either outdoor or inside buildings. What they share in common is that they require molecular filtration to protect people, processes or machinery, or simply to remove odours. In fact, there are more than 130 million registered chemicals in the world today, and our list of references and applications keeps growing.

WE PROVIDE SOLUTIONS IN THESE MAIN AREAS:

  • Corrosion control: Protection of sensitive electrical process control systems from acidic gases in petrochemical, pulp and paper, metal refining, printed circuit board manufacturing, data centres and wastewater treatment facilities. Corrosion control is also important for protecting artefacts in museums and storage facilities.
  • Microelectronic: Yield enhancement for semiconductor wafer manufacturing, flat panel displays, hard disk drives and equipment. Protection from outdoor and process chemicals present at trace levels in the air.
  • Indoor air quality: Protection of people staying inside buildings like airports, offices, hospitals or laboratories.
  • Exhaust: Protection of people and the environment from odours and toxins emitted in exhaust air streams from industrial facilities.

Additionally, we are a world leader in molecular filtration for nuclear facilities and special applications requiring safe change housings.

VERSATILE, ROBUST & EFFICIENT PRODUCTS SPECIALLY DESIGNED & TESTED

The corrosion control product range is supported by a comprehensive range of filters, sales tools and site services. We are a leading manufacturer of UL-certified activated alumina adsorbents (CamPure™) as well as plastic modules (CamCarb™), housings for filters and adsorbents (PSSA, VDBs) or analytical services (corrosion coupons, ISA Check online monitors, media post-mortem tests).

For the last 20 years, we have revolutionised molecular contamination control in microelectronic facilities with the introduction of GigaPleat™, the cleanest product on the market designed for cleanroom applications where activated carbon particle emissions and outgassing cannot be tolerated. GigaPleat is available with a wide range of adsorbent media such as ion exchange resins or activated carbon, adapted to the different chemicals observed in microelectronic facilities including, acids, bases, condensables, oxidants, VOC, dopants and refractory compounds.

Heavy-duty products are most often applied to the exhaust field with a range of so-called deep bed products (ProCarb) for high loads and/or very high removal-efficiency requirements, as well as containment applications (ActiCarb). Finally, our versatile product line also includes combination filters for air handling units with limited space to control both particulate matter and gaseous chemicals within a single filter stage (CityCarb).

All these products are specially designed and tested with chemicals relevant to each application. Our unique ISO 10121 molecular test rigs for full filter sizes as well as our lifetime calculation and design software bear witness to our 55 years of experience in this field and help to ensure proper dimensioning and guaranteed results.
