F9 Pre-filter: The pre-filter removes the majority of the submicronic respirable particles, protecting the critical downstream HEPA filter from strain and premature clogging. The filter media is encased in a strong aluminum cartridge to resist contamination bypass. The high surface area mini-pleat filter media ensures high capacity and efficiency for demanding applications.
Hydrophobic HEPA filter: This specialized HEPA filter is chemically compatible and resists the forces of the liquids found in dye sublimation processes. The HEPA filter is tested at 99.999% @ 0.3 microns. This means that it removes 99.999% of the most aerodynamically penetrating particles, known to be 0.3 microns, while smaller and larger particles are even more effectively captured, resulting in extremely clean air. The filter media is encased in a rigid aluminum cartridge to resist contamination bypass. Learn more. The high surface area mini-pleat filter media ensures high capacity and efficiency for demanding applications.
Gas Filter: The gas filter is filled with pure high-grade activated carbon, which removes the broadest spectrum sublimation-generated odors at the molecular level. 110 lbs of the adsorption media ensure high capacity and efficiency for demanding applications.
Why we use individually separated filters HEPA and gas filters vs. combined HEPA/Carbon filters:
Different processes emit different proportions of particles vs. VOC gases. With individually separated filters, each filter can be replaced when it actually is spent. In contrast, in a combined filter where the HEPA and Gas filters are inseparable, the barely used HEPA filter portion may have to be sacrificed because the gas portion is spent (or vice-versa). This is wasteful and less economic.
Why are Rigid Filter Cartridges so important?
Filtrabox systems use high-pressure vacuum blowers to suction the fumes out from the DTF oven and into high-efficiency filters. As the filters load up with contaminants, the negative pressure within Filtrabox increases. The sheet-metal cabinet and seals are designed to resist deformation and air leaks under extreme pressure. Therefore, the filters must also be able to resist deformation to prevent
contaminant leakage. All Filtrabox filter cartridges are built tough, using a thick aluminum box structure to resist flex so that the rubber seals can maintain contact with the sealing surfaces. Cardboard cased filters flex and crumple
under the pressure and moisture leading to leakage of contaminants.
