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.
