Big volumes dilute dust, but they also hide pockets of exposure. The solution is to control air movement where work happens, not just the whole cube of the building.

Map zones and sources

• Identify high-emission tasks (cutting, sanding, bag tipping) and create local controls first.
• Use light partitions or curtains to reduce mixing and define movement corridors.
• Plan make-up air routes so extraction can work without starved inlets.

Create push-pull corridors

• Set “push” air to bring clean air along work aisles and “pull” air to draw contaminants towards extraction endpoints.
• Place air scrubbers at the pull end and angle them to avoid recirculating dust into occupied zones.
• Keep forklift routes outside the pull path to prevent re-agitation.

Size and verify under load

• Target adequate air changes in the controlled zone, not the entire building.
• Use H13/H14 filtration for fine dusts and RCS risk tasks, and check airflow under load as filters accumulate dust.
• Validate with a particulate monitor at worker height; adjust fan angles and scrubber placement until readings stabilise.

Maintain performance efficiently

• Rotate or clean pre-filters to maintain flow and reduce energy use.
• Schedule zoning checks after layout changes or seasonal door use.
• Record PM trends; rising baselines usually mean leaks, blocked filters, or misplaced equipment.

Large-scale MAXVAC Dustblockers can act as the pull element at aisle ends when zoned correctly, helping maintain directional control without conditioning the whole building.

Practical takeaways

• Control zones, not the whole shed—push clean air and pull contaminants out.
• Partition, then size extraction for the zone and verify with PM data.
• Use high-efficiency filtration for fine dusts; maintain pre-filters to protect flow.
• Keep traffic and doors aligned with airflow, not against it.

With zoning, push-pull corridors, and verification, large spaces can maintain consistent air quality without wasteful whole-building ventilation.
