Operating at a 4 MFD capacitance with a 370V rating

Fail-Safe Operation: The mechanical spring return provides reliable system protection during power outages

meaning it requires a minimum pressure differential of 1 PSI to lift the diaphragm and allow flow

Standard 48-Frame Housing: Ensures a drop-in fit for most furnace blowers and small exhaust fans

Siemens Building Technology ASK71.14 Linkage Control Kit 320819-301 Operating at a 4 MFDThe Siemens ASK71. 14 Linkage Control Kit is an essential field mounting solution engineered for rigid surface applications requiring mechanical conversion from rotary to linear stroke output. Designed for professional integration with OpenAir GEB and GMA actuators, this bracket and crank arm assembly provides a secure transition for damper control when the actuator cannot be direct coupled. The kit is purpose built to facilitate indirect mounting for
