Each individual filter has a specific function within Filtrabox’s 3 stages of filtration:

1. Polymer Pre-filter: The liquid resistant polymer pre-filter protects the critical downstream HEPA filter from filter clogging ambient dust and liquid fog overload. 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 mid-sized applications.
2. Hydrophobic HEPA filter: The Hydrophobic HEPA media not only resists moisture, it is extremely strong and sheds excess liquid to provide the perfect barrier to the DTF Fog. 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 mid-sized applications.
3. Gas Filter: The gas filter is filled with pure activated carbon to remove unpleasant odors at the molecular level. 20 lbs of the adsorption media ensure high capacity and efficiency for mid-sized applications. See how activated carbon filters work.

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.

Other systems route the air from the top of the filters to the bottom. The Filtrabox DTF fume extractors reverse the direction of flow, from the bottom to the top. This allows gravity to assist in draining the accumulated liquid within the filters into the built-in reservoir below for more capacity. This novel arrangement also protects the electronics and blowers from contact with the liquid.

As filters become loaded with contaminants over time, they become more restrictive to airflow. The intelligent flow regulator proportionally increases power to the blowers to automatically overcome the restrictions and maintain consistent fume extraction. Just enter your flow setpoint and Filtrabox does the rest. Filtrabox will also let you know when to change filters.

Others try to achieve space savings by offering smaller machines. But this results in less filter capacity, more noise, and less airflow.
The Slim-line design shrinks the width of the extractor and relocates critical performance features into the plentiful depth dimension, allowing for maximum airflow, filter capacity, and noise reduction in a space-saving package -no compromises. Ask us for 3D models of our fume extractors to make your interior design/workflow layout a breeze.

Dust, splash-proof, and impact-resistant, the new membrane touchpad interface offers both improved protection against industrial contaminants and simplified intuitive control. A fume extractor should simply keep the air clean and work when you want it to work. The interface is canted to an optimal angle for better viewing clarity and easy touch actuation.

Our fume extractors comprise many complex electronics components and sensors to monitor and control their performance. However, we have simplified the Filtrabox by consolidating the components into two simple and removable
modules:

Electronics Module: This module includes all the interface, control, and power systems.
Blower Module: This module includes the blower and flow sensor.

In the event of a field issue, our tech support need only focus on diagnosing two modules to quickly dispatch the appropriate module to you for immediate replacement. The modules are simple to replace with only a few plug-and-play wire harnesses – no tech experience required.

All Filtrabox systems use digital blowers to create powerful, reliable suction. Traditional brushed blowers inevitably wear out, lose suction and need replacement. Filtrabox’s combination of digital contactless rotors and

contaminant-resistant hyper bearings allows for extreme rotational speeds and maintenance-free operation for years; more suction power – no maintenance.
