The 0551759 Surge Suppressor is a factory-specified fluid dampening component used on the Advantage 600 airless sprayer. It reduces pressure surges created by pump cycling, helping deliver smoother, more consistent material flow to the spray gun.
Without a properly functioning surge suppressor, pressure spikes can cause spray pattern pulsing, excessive vibration, and accelerated wear on hoses, fittings, and gun components. Using the correct OEM suppressor helps stabilize system pressure and extend component life.
| Pressure dampening | Absorbs pressure spikes from pump cycling |
|---|---|
| Flow smoothing | Reduces pulsation in the spray pattern |
| System protection | Minimizes hydraulic shock to hoses and fittings |
| Spray pulsing | Noticeable surging at the spray gun |
|---|---|
| Pressure instability | Inconsistent pressure despite proper pump service |
| Fluid leaks | Leakage at suppressor body or fittings |
| Routine overhaul | Replaced during major fluid-system service |
Part 0551759 is compatible with the following airless sprayer. Always verify placement and configuration using the correct parts diagram.
