SPD Series - ConservAIR Flow Controls

The Intermediate Control (I/C)® SPD Series monitors and stabilizes the delivered air pressure by adjusting flow. The SPD Series releases air from an upstream receiver to maintain a continuous supply pressure at the lowest optimal level. The result is reduced waste from leaks, improved system efficiency and significantly lower operating costs.
