Applications
Built for constant-airflow duty against a varying system resistance: laboratory fume hoods and VAV terminal boxes that must hold face velocity within ±10 % as the sash moves, cleanroom and pharmaceutical FFU / HEPA terminal housings whose airflow must not drift as filters load up, spray booths and dust collectors whose media resistance rises through a shift, drying and curing tunnels that need a fixed process-air volume, and greenhouse CO₂ enrichment where the air change rate itself is the setpoint. Commissioning engineers select one of the four PWM/Vsp duty curves to set the design airflow (600 / 450 / 300 / 180 m³/h) and the EC motor holds it without re-balancing the ductwork. Typical installations run between 100 and 300 Pa system resistance; beyond that the operating point climbs the steep branch of the curve and airflow collapses toward the 480 Pa shut-off point.
