Negative Air Machines Extend Much Broader Abatement Coverage
Remediation contractors increasingly specify negative air machines that deliver regulatory clearance capacity standard portable scrubbers alone cannot support reliably across expanding mold and asbestos abatement programmes, where sustained clearance reliability matters more than the added equipment cost negative air architecture introduces, with providers such as Therma-Stor expanding negative air production capacity to meet rising specification demand across their growing contractor customer base worldwide. Negative air segment demand grows about 18% of category revenue, and gross margins run 28% to 35% across the category. This trend continues accelerating through coming years across North American abatement jurisdictions.
Market Impact: clearance priorities add 2-4% growth
