These filters are recommended for organic, inorganic, chemical and ammonia based gases into industrial applications, and dust. The design of GVS’s third generation carbon and dust filter is based on two patented technologies: “Encapsulation†of the HESPA filter media enables a curved, low profile design and optimizes the resistance of pleated dust filter element. Use of graduated carbon extends the gas molecule path through more adsorbent filter material and therefore maximizes the gas performance compared to conventional filters. The result is a high performance filter that is 30% smaller in size and weight of the average filter.
