Fume control, matched to the off-gas — not the catalog page

A chemical scrubber (wet scrubber) removes contaminants by contacting the gas stream with a scrubbing liquid — effective for acid gases and specific chemical fume streams. A biofilter uses biological media to break down odor-causing compounds — generally suited to different contaminant types and flow characteristics. The right choice depends on the specific gas stream composition, not a default preference.

Same discipline as any wetted chemical equipment — the scrubber body, packing media, and mist eliminator materials need to be confirmed compatible with the actual gas stream's chemical composition and concentration, not assumed from a general 'acid-resistant' marketing claim.

Per the Zero-Guesswork Controls gate, a scrubber's control narrative should define what happens on scrubbing-liquid low-level, pH excursion, or fan failure — a scrubber that's electrically running but has lost recirculation flow can pass contaminated air through untreated while appearing operational.

No — real capture-equipment sizing (per Finish Thompson's FT30 vector capture line) also accounts for the specific chemical vapor being captured and its compatibility with the wetted capture-system materials, not just CFM throughput.
