Powder Coating Vacuum Solutions

Grounded. Contained. Color-change ready.

Powder coating charges combustible polymer powder on purpose — which makes ungrounded cleanup equipment uniquely wrong for the environment. PrestiVac recovery systems close the loop the booth doesn't: fugitive overspray, color changeover and hopper cleanout, with grounding verified end to end.

    Fines retained; next color protected

  • Static Control

    Grounded recovery in an electrostatic process

  • Faster Color Change

    Single-pass cleanout on the critical path

Overview

The spray booth reclaims overspray by design — that's the process working. The housekeeping gap is everything the booth's own recovery doesn't own: fugitive powder that settles beyond capture, hopper and feed-area spills, rack and fixture buildup, and the color-change cleanout that sits directly on the production schedule. Coating powders are combustible polymer dusts, the environment is deliberately electrostatic, and the collected material is a waste stream that must never contaminate the reclaim stream.

  • Color Changeover

    Booth cleanout on the critical path

  • Booth & Hopper Areas

    Feed spills & residual powder

  • Fugitive Overspray

    Beyond the booth's capture

  • Racks & Fixtures

    Hanger and conveyor buildup

Challenges in powder coating

  • Coating powders are combustible polymer dusts — NFPA 33 spray-application territory, inside NFPA 652/660's DHA obligation
  • The process is deliberately electrostatic: charge is everywhere, and ungrounded cleanup gear adds risk exactly where it concentrates
  • Color-change cleanout sits on the production critical path — housekeeping speed is throughput
  • Fugitive powder settles beyond booth capture, on structure and equipment
  • Reclaim purity: floor-collected and fugitive powder is waste, and mixing streams contaminates expensive reclaim
  • Exposure considerations vary by chemistry — TGIC-bearing powders carry stricter handling

Why engineered vacuum recovery?

  • Explosion-proof construction for combustible polymer dust
  • Grounded, bonded path — the non-negotiable in an electrostatic process
  • Single-pass cleanout shortens color change instead of stretching it
  • HEPA-retained exhaust keeps fines out of booth air and the next color
  • Stream separation protects reclaim purity by rule, not vigilance
  • Supports compliance with NFPA 33 / 660 and OSHA housekeeping

Solution benefits

  • Better Safety

    Grounded explosion-proof recovery in a process that charges powder by design.

  • Higher Productivity

    Color change becomes a plannable single-pass method on the schedule.

  • Cost Savings

    Stream separation protects expensive reclaim powder from contamination.

  • Cleaner Workplace

    HEPA-retained fines stay out of booth air and the next color.

Typical system setup

  1. 01

    Booth / color-change point

    Residual and fugitive powder at the source

  2. 02

    Grounded tool kit

    Stainless wands and crevice tools, non-sparking

  3. 03

    EX vacuum unit

    Explosion-proof; grounding verified before use

  4. 04

    Multi-stage + HEPA

    Powder load staged; fines retained at 99.99%

  5. 05

    Sealed waste container

    Kept strictly separate from the reclaim stream

Collected floor and fugitive powder is a waste stream — reclaim purity lives in the booth's own recovery system, and keeping the two separate is the specification.

Powder Coating FAQ

The booth already recovers overspray — what's left for a vacuum?

Everything outside the booth's capture: fugitive powder on structure and equipment, hopper and feed spills, rack buildup, and the color-change cleanout itself. The booth is a process recovery system, not a housekeeping program.

Why is grounding emphasized so heavily here?

Because the process charges powder electrostatically on purpose — static is guaranteed, not incidental. Recovery equipment must be part of the grounded system, verified before use; an ungrounded vacuum is an isolated conductor in a charged space.

Can vacuum-collected powder be fed back to reclaim?

No — floor-collected and fugitive powder is contaminated by definition and is handled as waste in sealed, segregated containers. Reclaim purity lives in the booth's own loop; the streams never mix.

Does cured coating create a dust hazard?

The fused film on finished parts is inert — the hazard is the uncured powder. That's why the program targets booth perimeters, hoppers, changeovers and fugitive settlement rather than finished work.
