Laboratory Exhaust & High-Velocity Induced Flow Systems
High-velocity induced-flow lab exhaust for research, hospitals, and containment zones, ANSI/AIHA Z9.5 and NFPA 45.
Overview
Advanced, engineered exhaust systems for critical containment zones, research laboratories, hospital isolation rooms, and high-chemical environments. High-velocity induced-flow fans safely dilute hazardous fumes and effluent bypass air, projecting them high above the building roofline to prevent re-entrainment into fresh air intakes. Constructed from corrosion-resistant alloys or specialized coatings, the assembly features integrated bypass air dampers and dynamic control packages to maintain precise static pressure. Fully compliant with ANSI/AIHA Z9.5 and NFPA 45, delivering validated structural safety, certified acoustic performance, and a minimized rooftop architectural footprint compared to conventional tall-stack utility fans.

Specification Highlights
What this system delivers.
- +01
Induced-Flow Plume Projection
High-velocity discharge dilutes effluent and lifts it above intakes, preventing re-entrainment.
- +02
Corrosion-Resistant Construction
Alloys and coatings selected for aggressive chemical and biological exhaust streams.
- +03
Closed-Loop Pressure Control
Bypass dampers and dynamic controls hold tight static pressure across variable lab loads.
- +04
Minimized Rooftop Footprint
Replaces tall utility stacks with a lower-profile architectural solution.
