The Graco 17P434 Regulator, Po 400 SCFM 5-160 PSI is a high-capacity industrial air pressure regulator designed to deliver stable and precise airflow control in demanding spray and fluid handling systems. Built for heavy-duty environments, it manages large-volume air supply (up to 400 SCFM) while maintaining adjustable outlet pressure between 5 to 160 PSI.
This regulator is engineered for use in professional-grade coating, spray foam, and industrial manufacturing applications where consistent air pressure is critical for performance and finish quality. It helps prevent pressure fluctuations that can affect spray pattern consistency, material output, and system efficiency.
Manufactured by Graco, a leading name in fluid handling systems, the 17P434 is part of their industrial-grade component lineup designed for durability, precision, and long service life in continuous operation environments.
