Gas- and molecular filtration

Range of application

Activated carbon, Zeolithe and impregnated aluminiumoxide have proven very well to securely adsorb air-born gas pollutants, which are often detrimental to health and environment. We offer a broad range of adsorbents and filters for use with air-conditioning, air-ventilation and extraction and recycling applications.

HS-Activated Carbons

Activated carbon for gas- and odor filtration. Availiable as bag- or bulk goods.

  • 65°

HS-Luftfilterbau supplies Activated Carbone in shaped and pulverised format. The granule size of shape and corn coal ranges between 0.6 and 6.3 mm, according to it’s application, pulverised activated charcoal has a granule size of <0,075mm. This activated charcoal is manufactured from various raw materials, compost, coconutshells or sugar. This is achieved either by burning, or special treatment procedures to achieve a substantial enlargement in the “outer” and “inner” surface.

Through this process the finest porous surfaces and the finest capillary systems are created, which increases the absorbent surfaces up to 1700 m²/g. This in turn results in excellent filter efficiency and dust storage capacity and enables a long life span and high capacity of the active coal filters. Basic rules with the use of active carbon:

  • with increasing virtual contact with the active carbon or larger amounts of coal being used, the efficiency of the coal used is increased.
  • For the absorption of special pollutants impregnated active coal is used.
  • The air temperature of the flowing air shall not exceed 50ºC as from this temperature onwards some of the pollutants will be released by the coal. Any materials to be filtered have to absorbable. (Refer to table).
  • Active coal is very sensitive towards dust, and therefore it is recommended to use high quality and efficient dust filters as a primary filters for non-gaseous pollutions.
  • The basic rule: any gas molecules, which have more than three non-hydrogen atoms, are easy to absorb.

Please contact us for more, specific informations about the materials you need to adsorb.

HS-Amosorb - Ammoniafilter

Compact ionexchanger for radical NH3 elimination.

  • 65°

HS-Amosorb is specially designed for the filtration of ammonia from air flows. This filter has an approximately 5-fold higher efficiency against gaseous ammonia than comparable solutions based on activated carbon. Due to the construction HS Amosorb reaches an approximately 60-90% lower pressure drop as solutions based upon activated carbon of similar size. In addition to these advantages, HS Amosorb is also very air flow tolerant - even at 30% overload operation!

HS Amosorb reached its outstanding efficiency through the use of micro-ion exchangers, which are laminated to a carrier fleece. The chemical reaction of ammonia gas with the ion exchangers is spontaneous. In this respect, the apparent contact time (and thereby the airspees) of the gas plays a minor role with the filter medium.HS-Luftfilterbau offers mobile filterunits with HS-Amosorb Filter. These mobiles filters meet the requirements for mainenance tasks on HVAC Units and chillers that operate with Ammonia (NH3) as cooling agent.
