ACTIVATED CARBON FILTERS (and other active substances) AND COMBINED FILTERS

The filter material in the active air filters is usually made of granulated highly activated carbon

The adsorption material of the activated carbon filter is activated charcoal. Depending on the impurities which must be removed from the air, we use activated carbons of mineral or vegetable origin, physically or chemically activated, different in size of the active surface area and, consequently, index of activity. By using various granulations of activated charcoal we achieve air pressure drop that is required by the ventilation device of the filter user.

The activated carbon filters remove organic contaminants from the air, such as the vapor of the solvents and various unpleasant odors. For the removal of certain inorganic contaminants from the air, such as ammonia, H2S, and certain toxins, which are not adsorbed on the activated carbon, we use specially impregnated activated charcoal, which is effective in the removal thereof.

In the manufacture of the active filters with special technology we ensure a homogeneous distribution of carbon within the filter cartridge, thus enabling high-quality filtration and long service life of the filter.

Filter cartridges are manufactured in different shapes and sizes according to customer specifications.

Filters with activated carbon can function independently, but can be added an aerosol filter at the entry and a finer filter at the exit, which prevents the leaking of micron particles of activated carbon in the purified air. Aerosol filters remove aerosol particles from the air, hence prolonging the service life of the activated carbon filter.

Based on years of research and experience in air filtration, in cooperation with external partners from Slovenia and abroad, COLF d.o.o. has developed a combined air filter which combines two filters – aerosol filter and activated carbon filter. With the use of a combined air filter we achieve exactly the same cleaning effect as by air filtration through a separate aerosol and active carbon filters, while at the same time the compact version of the combined filter cartridge also has several other advantages:

  • Installation requires less space
  • Simpler installation and servicing
  • Cost-effectiveness (price of filters and servicing)
  • Good energy efficiency
