Lifa HS 3G Filter

The Lifa HighSecurityFilter system is specifically designed to protect  against microorganisms and chemicals.  

Multi-stage filtering is done using the 3G filter, which removes most solid particles and gaseous pollutants. Then the dirty air passes through a ULPA filter (low permeability filter) that holds out the smallest particles: solid, liquid, and also radioactive. Ultraviolet radiation is used to kill bacteria. Then, the air flow passes through an activated charcoal filter that absorbs gases by physical and chemical influences. The centrifugal fan recovers the pressure that falls due to ULPA and absorbent filters. The Lifa3G filter is a pre-clean filter to reduce the contamination of the ULPA filter and load the NBC filter so that it can be continuously cleaned.

Filtration of solids

Current standard filtering microorganisms from the air stream is a high-performance air filter HEPA. This filter is also used in military and nuclear industry. As a HEPA filter cleaning system set up carbon filter to remove not only microorganisms and solid aerosols but also liquid aerosols. It also protects from atmospheric carbon filter dust.

Minimum filtration HEPA filters as a percentage – 99.97% 0.3 micrometer (micron) size of the particles. Thanks to the efficiency and ULPA filters 3G, efficiency filter LifaHighSecuritysche above – 99.9999% + 0.3 micron.

Filtering the gas phase

Filter standard chemicals made through a dense layer of activated, impregnated carbon granules. Carbon filter uses two different processes to remove molecules from the air, such as: physical adsorption and chemical reaction.

Testing of carbon filter

Working activated carbon LifaHighSecurityprotyboyovyh toxic substances tested, for example, using the following gases:

  • Chloropicrin for the physical adsorption (nerve gas)
  • Cyanogen chloride for chemical adsorption
