🎛️ Demand Ventilation (NFPA 33 Paint Booths / NFPA 96 Kitchens, VFD Flow Tracking 50%-100%)

VAV Make-Up Air Interlock Calculator

Size variable-air-volume (VAV) demand-controlled make-up air modulation systems for commercial kitchen hoods (NFPA 96) and industrial spray paint finishing booths (NFPA 33 / Melink Intelli-Hood): track exhaust fan VFD speeds (50% to 100% dynamic airflow modulation based on optical smoke/temperature sensors), slash winter gas heating bills by 40%, and energy retrofit profits.
