SprayTech part 0277371 is a fan noise foam insert designed to reduce operational noise and absorb vibration in compatible CS series sprayers. This acoustic foam is strategically placed around cooling fans and internal compartments to dampen sound and prevent rattling. Replace a deteriorated, compressed, or damaged foam insert to maintain quiet operation and prevent component vibration.

The 0277371 fan noise foam is an acoustic dampening component used in SprayTech CS 8100, CS 9100, CS 9900, and CS 9960 sprayers. It is strategically positioned around cooling fans and within internal cavities to absorb airborne noise, reduce vibration, and prevent rattling of components during operation.
Over time, foam can deteriorate due to heat exposure, oil absorption, or simple aging. It may become brittle, crumble, compress permanently, or lose its acoustic properties. A degraded foam insert can lead to increased operational noise, vibration transfer to other components, and potential loosening of parts. Replacing it with this genuine SprayTech foam restores quiet operation and maintains the sprayer's acoustic performance.
| Sound dampening | Absorbs operational noise from cooling fans |
|---|---|
| Vibration reduction | Minimizes vibration transfer to housing and components |
| Rattle prevention | Prevents loose components from vibrating against each other |
| Crumbled / deteriorated | Foam breaking apart or turning to dust |
|---|---|
| Compressed / flattened | No longer provides effective sound absorption |
| Oil / chemical soaked | Absorbed fluids may cause degradation |
| Increased noise | Noticeably louder operation or rattling sounds |
SprayTech part 0277371 is designed for use on the following CS series sprayers. Always verify placement by consulting your machine's parts manual.
| SprayTech Model | Component |
|---|---|
| CS 8100 | Fan noise foam |
| CS 9100 | Fan noise foam |
| CS 9900 | Fan noise foam |
| CS 9960 | Fan noise foam |
When replacing fan noise foam, inspect these associated components for wear or damage.
Check fan blades for damage and motor bearings for noise.
Inspect for cracks or loose mounting that could cause vibration.
Ensure screws and brackets are tight; loose hardware can amplify noise.
