RIDGID GP90135A Unloader With Muffler Flare Assembly

RIDGID GP90135A Unloader With Muffler Flare Assembly is an OEM replacement component for RIDGID 105/135 wheelbarrow air compressors, pairing the unloader valve with a muffler flare to reduce exhaust noise while the unit unloads and primes. The unloader is designed to control engine RPM during unloading, and the operator’s guidance notes that the unloader lever should be positioned horizontal to start the engine and allow unloading, contributing to smoother restarts. This assembly is specified for GP90135 and GP90135A models and supports the 105/135 family of RIDGID wheelbarrow compressors, delivering the essential function of relieving pump load at idle to enable safe, controlled startup and operation in portable shop environments.
