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 CompactX-DTF) to suit any production volume, small and large.
Why do I need the Filtrabox D-FOG 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. The dense, fog 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.
