The Multiquip 30700Z1C811 is a genuine OEM Noise Suppressor Cap Assembly designed for a range of Multiquip gasoline-powered generators, arc welders, concrete mixers, and plate compactors. As a factory-sourced component, 30700Z1C811 delivers the exact fit and electrical suppression performance the original equipment was engineered around. This assembly is confirmed compatible with GA3.6HR generators, GAW180HE, GAW180HE1, and GAW180HEA welders, the MC12PH concrete mixer, and MVH208GH, MVH308GH, and MVH408GH plate compactors. Sourcing the correct OEM cap ensures ignition integrity and protects sensitive onboard electronics from interference.
Key Features
- OEM Ignition Suppression Spec — Matched to the exact resistance and shielding specification of the original component, ensuring no signal bleed or misfires caused by an incorrect cap.
- Direct Plug-In Replacement — Mounts directly onto the spark plug boot without modification, maintaining the factory ignition lead connection geometry.
- Broad Cross-Equipment Compatibility — Fits GA3.6HR, GAW180HE series welders, MC12PH, and MVH208GH / MVH308GH / MVH408GH plate compactors under a single part number.
- Protects Electronics from Ignition Noise — Suppresses high-frequency radio frequency interference (RFI) generated at the spark plug, protecting onboard meters, controls, and connected equipment.
- Electrical Safety Compliance — A correctly rated suppressor cap prevents stray ignition voltage from creating shock hazards or arc events at the plug terminal during operation.
A noise suppressor cap assembly fits over the spark plug terminal and acts as a filter between the ignition system and the rest of the machine's electrical environment. It absorbs and dampens the high-voltage electrical spikes produced at the moment of ignition, preventing that interference from radiating into control circuits, instrumentation, or any equipment connected to the machine's output. When the suppressor cap degrades — through cracking, carbon tracking, or internal resistor failure — engines can misfire, meters can display erratic readings, and in generator or welder applications, connected loads may be exposed to noisy or unstable power.
