Vacuum solutions engineered for cleanrooms & controlled environments

The one environment where the vacuum's own cleanliness is a design requirement — a cleanroom is defined by its particle count, so recovery equipment either belongs to the cleanliness system or becomes a breach in it. There is no third option.

Cleanrooms & Controlled Environments production process explorer

Every stage. Every challenge. The right vacuum solution.

A cleanroom's contamination geography runs from the gowning threshold to the return-air path — and everything in it, including the recovery equipment, is measured against a class. Walk the stages.

Stage 01 — Gowning & airlocks

Contamination control starts at the threshold — equipment enters wiped down and gowning-compatible, because whatever crosses the airlock is measured against the room's class from that point on.

Key challenges

When the particle count is the product

  • The Vacuum Is In The Spec

    A cleanroom is defined by particle count, so recovery equipment must be validated as part of the cleanliness system — exhaust cleaner than the room, or it's a contaminant.

  • ISO 14644 Classes

    Rooms are rated by particle concentration, and the rating is a product requirement — housekeeping holds the class rather than chasing visible dirt.

  • HEPA Isn't Always Enough

    The most demanding classes call for ULPA-grade retention — the filtration is matched to the class the room must hold.

  • Don't Disturb The Flow

    Laminar and unidirectional airflow is a control in itself; recovery must clean without disrupting the airflow protecting the critical work.

  • Wipe-Down Everything

    Smooth, cleanable, gownable equipment is mandatory — the recovery gear enters the protocol like everything else, or it doesn't enter.

  • Cleanliness Is Measured

    Particle counts are recorded against the class, so housekeeping is a validated, documented outcome — never an assumption from appearance.

Representative case study

Dual-Hazard Dust Control in a Semiconductor &

How a representative advanced-electronics manufacturer runs housekeeping where the clean floor hides two hazard classes at once — toxic dopant, etch and CMP residues that are not combustible, and genuinely combustible dust the 'high-tech means inert' assumption misses: fine silicon from wafer grinding and the reactive-metal powder that advanced packaging brought onto the fab floor.
