GMA126.1U Open Air Actuator","description":"\u003cdiv\u003e\u003cp\u003eOpenAir GMA126.1U is a spring-return rotary damper actuator from Siemens Industry, designed to drive HVAC dampers between two fixed positions with a robust 62 in-lb (7 Nm) of torque. It supports 24 V AC\/DC operation and 120 V control options, enabling flexible installation for both low-voltage and line-voltage control schemes, and it uses direct-coupled electronic actuation with a 90-second travel time between end positions in 2-position control. The unit includes built-in spring return, so the damper returns to its default position when power is removed, and it provides dual auxiliary switches for end-of-travel or status signaling. Cables are included as standard, and the enclosure is NEMA 1 for indoor installations. As part of the OpenAir series, the GMA126.1U is commonly used on air-handling units, rooftop units, and other ventilation applications where reliable fail-safe damper positioning is essential in 24 V or 120 V control configurations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268027011306,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-industry-inc-gma126-1u-open-air-actuator","provider":"GTG Hardware","version":"1.0","type":"link"}
