Submicron exhaust control for an NC plastics plant
Source capture and separation upgrades that cut mass loading and fan energy while production continued.
Constraint
Submicron particulate and solvent load stressed exhaust and separation. Adding fan CFM was the default capital path, but capture at the source was weak.
Approach
Mapped sources and duct constraints. Separated capture geometry from true capacity shortfalls. Used CFD where layout options changed capital. Phased mechanical packages into production windows.
Result
Mass removal improved on the agreed measurement path. Fan energy dropped versus the upsizing baseline. Work completed without an extended plant stop.
Verification
Pre and post mass and energy metrics scoped to the exhaust system under review.
What we would not do
Did not default to fan upsizing before fixing source capture geometry.

What helps a first conversation
- Process type (e.g. plastics, textiles, welding)
- Capture or exposure symptoms
- Current exhaust / fan notes if known
- Planned shutdown or outage windows
We fix source capture before defaulting to more CFM or larger fans.
