Overview of Filtration Group HEGA Filters
HEGA (High Efficiency Gas Adsorber) filters deliver superior gas-phase filtration for facilities seeking clean, odor-free air. Built with patented carbon-loaded media, they effectively target specific airborne contaminants such as VOCs, diesel exhaust, ammonia, and acid gases. With customizable frames and depths, they provide versatile, high-performance solutions for critical air quality challenges.
Targeted Odor and Gas Removal
HEGA filters are engineered to address a wide spectrum of gaseous pollutants with grade-specific solutions. Grade 653 efficiently removes VOCs, 651 neutralizes diesel exhaust, 876 targets acid gases, and 147 captures ammonia and amines. This versatility ensures that facilities can match the right filter to their unique contaminant challenges.
Advanced Carbon-Loaded Media
Each filter incorporates patented nonwoven media infused with high-activity virgin activated carbon. The structure maximizes surface area for adsorption while remaining non-dusting, lightweight, and resistant to microbial growth. This design not only ensures maximum gas-phase capture but also maintains structural integrity and cleanliness in sensitive environments requiring consistent air quality.
Flexible Configurations for Any Application
Available in 2", 4", 6", and 12" depths, along with box style, single-header, and double-header options, HEGA filters adapt to diverse system requirements. Frames are offered in die-cut board, plastic, or galvanized steel, providing durability and installation flexibility to meet the needs of any facility or HVAC system.
