Damper actuators is applicable to a control air-conditioning system components. Actuator based on specific uses are divided into different types, such as the mechanical function of the actuator (spring to recover actuators, rotary actuators, linear actuators, the maximum demands of force or torque actuator, etc.), electrical components and systems are compatible actuator (input voltage, control signal type, etc.). In principle, Siemens Building Technologies Inc. actuators for the system components for all types of conventional control signals. OpenAir actuator series can be widely compatible with all existing similar actuators. OpenAir Actuator Series features Damper positioning intuitive display Silent Running Concept of green products Low power C. stroke actuators and linear actuators A variety of standard signal With or without spring return function Globally recognized All models can be manually operated Driving force for the size of the file automatically to find a positive shaft couplings, installation time is shorter Adjustable scope of work Modular design concept, quickly adapt to user needs Apply to all applications of the product line Circulation of air, sending the new wind and closed-conditioning unit Smoke suction device and skylights adjustable air-valve VAV unit Air-conditioning system control device Compact control unit Air handling and distribution Economical The long-term reliable operation Reasonable price Pre-connect and auto-aligning shaft couplings, ease of installation, shorter Easy to maintain Low power Uniform size of standardized chassis Replacement of a failing component, instead of scrapping the whole actuator
