This replacement sail assembly actuates the switch when duct velocity reaches the required threshold, ensuring auxiliary equipment operates only during active blower cycles. Designed for light commercial and residential HVAC systems, it withstands static pressure fluctuations and prevents equipment operation during low-flow conditions.
