ALWAYS WORK IN A WELL VENTILATED AREA and use Protective Equipment (including masks and gloves) when working with specialty printing and curing products and processes (including DTF, DTG, UV etc.) as fumes and processes may be hazardous. We highly recommend the use of a fume extractor when working with DTF powder in addition to good ventilation and filtration in your work area.
DTF Transfer Printing Fume Extraction
Introducing Filtrabox’s DTF series fume extractors for Direct-to-Film (DTF) printers. The Filtrabox DTF fume extractor captures the thick oily fog generated during the curing of the printed transfers. Produce quality transfers for garments and other substrates in a clean air environment – your products and employees will benefit! These extractors feature reinforced filters, large liquid reservoirs, and protected electronics to handle your demanding applications. Two sizes are available (Micro-DTF and the Compact-DTF) to suit any production volume, small and large.
Why do I need a fume extractor for the DTF process?
The process starts with a DTF inkjet printer laying down specialized inks onto special plastic PET films. These films are known as DTF Transfer Films. Then, DTF hot-melt adhesive powder, a white granular product, is applied to the printed transfer film. The powder is evenly applied to the film with a powder shaker. The powder only sticks to the areas that have ink on them. The powder shaker literally shakes off the excess powder off the film. The film is then transported into a small curing oven that is used to melt and bind the hot melt powder onto the transfer film. The hot-melt adhesive does not actually release fumes at this stage because of the nature of the thermoplastic adhesives used.
However, the oven boils away the excess liquid from the inks and creates a fog that is made up of a concentration of tiny liquid droplets. This is where fume extraction is required. Our DTF fume extractors are specifically designed to capture these microscopic droplets. This is necessary to keep the work environment, product and equipment clean and fog-free. The Filtrabox DTF Fume Extractors feature reinforced liquid-resistant prefilters and Hydrophobic HEPA filters for efficient and reliable removal of fog particles. The unique reverse-flow configuration of the Filtrabox DTF fume extractors ensure that accumulated liquids do not reach the blowers and electronics for reliable performance you can count on. A liquid reservoir is built into each fume extractor to capture excess liquids that build up within the system which then can be drained at your convenience.

Features
3 Stage Filtration: Rigid Separated Filters
Each individual filter has a specific function within Filtrabox’s 3 stages of filtration:
TM22 Filters Cutaway
Polymer Pre-filter: The liquid-resistant polymer pre-filter protects the critical downstream HEPA filter from clogging ambient dust and liquid for 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 small applications.
Hydrophobic HEPA filter: The Hydrophobic HEPA media not only resists moisture but is also 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. The high surface area mini-pleat filter media ensures high capacity and efficiency for small applications.
Gas Filter: The gas filter is filled with pure activated carbon to remove unpleasant odors at the molecular level. 10 lbs of the adsorption media ensure high capacity and efficiency for small 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.
Reverse Flow Configuration
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.
Intelligent Flow Regulator
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.
Robust, Simple User Interface
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.
Fast and Friendly Tech Support: Modularity for Serviceability
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 module:
Electronics Module: This module includes all the interface, control, blower, and power systems.
In the event of a field issue, our tech support need only focus on a basic diagnosis to quickly dispatch the module for immediate replacement. – no tech experience required.
Extreme Air Power: Digital Blower w/ Hyper bearings
