PrestiVac

Vacuum solutions engineered for commercial printing

The industry where combustible dust hides behind an ordinary pressroom — paper dust from cutting, trimming and folding is one source, but offset printing adds a starch-based anti-set-off spray powder that coats the shop, and digital printing adds fine toner. All three are combustible fine powders, and all three accumulate on presses and structures unless captured.

Commercial Printing production process explorer

Every stage. Every challenge. The right vacuum solution.

A printing operation moves paper through cutting, printing, finishing and binding, shedding combustible dust that differs by press technology. Walk the stages and their powders.

Stage 01 — Paper receiving & cutting

Guillotine cutting and trimming shed combustible paper dust at the front of the shop — the first and most consistent dust source in printing.

Key challenges

Three combustible powders in one pressroom

  • Paper & Trim Dust

    Cutting, trimming, folding and finishing shed combustible paper dust throughout the pressroom — the constant background dust of printing.

  • Anti-Set-Off Spray Powder

    Offset printing uses starch-based spray powder to prevent ink transfer — a fine combustible powder that coats presses and the surrounding pressroom.

  • Toner Is A Fine Powder

    Digital printing handles fine toner, a combustible polymer and carbon powder captured HEPA-retained and sealed.

  • Two Print Worlds

    Offset (spray powder) and digital (toner) each shed their own combustible fine powder alongside the shared paper dust.

  • It All Accumulates

    Paper dust and spray powder settle on presses and structures, building fugitive combustible dust between cleanings.

  • Fine & Clinging

    Toner and spray powder are fine and cling to equipment, so HEPA-retained recovery is essential to keep them contained.
