KNOKOO installs fume extraction system for digital printing workshop

KNOKOO says it helped a 350-square-meter overseas print shop cut odors, dust and noise with a distributed fume extraction setup for UV flatbed printers, eco-solvent machines and DTF curing ovens. The installation was designed to improve air quality, reduce printer contamination and lift production capacity in digital signage and garment printing.

Why it matters: - Digital printing shops can face a mix of dry powder, solvent odor and airborne dust that affects workers and equipment. - KNOKOO positioned the installation as a way to improve indoor air quality while protecting printheads, rails and output quality. - The project also shows how source-capture systems can support environmental compliance in workshops with multiple print processes.

What happened: - Shenzhen Knowhow Technology Co., Ltd., which markets itself as KNOKOO, deployed a fume extraction solution in a 350-square-meter print shop overseas. - The workshop uses three UV flatbed printers, two eco-solvent photo machines and two DTF garment printing lines. - KNOKOO recommended a distributed, source-capture approach instead of a single centralized ventilation system. - For more information, KNOKOO directs readers to its company website.

The details: - Two FES600 industrial fume extractors were connected to the exhaust ports of the two DTF curing ovens with heat-resistant ducting. - Three FES150 compact fume extractors were installed behind the three UV flatbed printers. - Each FES150 unit used a wear-resistant extraction arm positioned near the printhead area. - The system used multi-stage filtration. - The pre-filter stage captured airborne fibers and larger adhesive powder particles. - The pre-filter can be upgraded to a metal-mesh oil-mist filter for oil-based inks and aerosol-heavy jobs. - The H13-grade glass-fiber HEPA layer captured 99.97% of dry digital dust down to 0.3 microns. - The activated carbon stage used high-iodine-value columnar carbon to absorb chemical odors and VOCs from UV inks and eco-solvent evaporation. - KNOKOO said the same equipment series can be extended with specialized oil-mist pre-filters for higher-concentration aerosol loads. - The company said the configuration can be scaled station by station without redesigning the full ventilation network. - The company’s product range covers soldering, laser and printing applications.

Between the lines: - The case reflects a broader shift in digital print production, where air handling is becoming part of the production workflow rather than a separate facility concern. - The source-capture setup is designed to keep contaminated air from moving across the shop before treatment. - The installation also fits KNOKOO’s broader pitch as a one-stop industrial purification provider for different manufacturing segments. - KNOKOO describes its business model around low-noise, energy-efficient engineering, batch quality control and site-specific support.

What's next: - KNOKOO said its systems can be adapted for other overseas workshops and local process layouts. - The company expects demand to keep rising as brands and regulators focus more on indoor air standards and workplace health. - Future installations may use similar distributed capture designs for mixed-emission print floors and other industrial environments.

The bottom line: - KNOKOO is betting that targeted fume extraction can solve three problems at once: cleaner air, better equipment uptime and higher output.
