Description
The Crandall 2372-351-CSS Low Pressure Selector/Volume Booster Relay is a pneumatic control relay designed to improve and amplify low pressure pneumatic signals in HVAC systems. This selector/booster unit increases the volume of a small input pressure signal so that downstream pneumatic actuators and controls can respond more quickly and accurately. Built to Crandall quality standards, it delivers stable performance and helps maintain consistent pneumatic control behavior in system logic circuits. Ideal for HVAC technicians and controls contractors, it supports dependable pneumatic signal management and system responsiveness in commercial and industrial applications.
