The SprayTech 0279937 CapSpray Air Filter Set is a complete filtration maintenance kit designed for SprayTech CS-series air-assisted airless sprayers. This set includes all necessary filters to clean and condition the compressed air supply, protecting sensitive air components from contaminants like moisture, oil, and particulates. Clean air is essential for consistent spray performance and preventing damage to air controls, regulators, and atomization systems.
Clogged or saturated air filters can lead to reduced air flow, inconsistent atomization, pressure fluctuations, and premature failure of air system components. Regular filter replacement as part of preventive maintenance ensures reliable sprayer operation, consistent finish quality, and extends the service life of expensive air system components. This OEM filter set is engineered to match original equipment specifications for optimal performance.
Air filters should be inspected regularly and replaced based on operating hours or when visible contamination is present. For best performance in challenging environments (high humidity, dusty conditions), more frequent replacement may be necessary. Always follow the sprayer manufacturer's recommended maintenance schedule for filter service intervals.
| Particulate removal | Traps dust, dirt, and solid contaminants from compressed air lines. |
|---|---|
| Moisture separation | Removes water vapor and liquid moisture from the air supply. |
| Oil coalescing | Captures compressor oil and lubricant vapors (if present). |
| System protection | Prevents contaminants from reaching sensitive air components. |
| Consistent performance | Maintains proper air flow and pressure for reliable atomization. |
|---|---|
| Component protection | Extends life of air regulators, solenoids, and controls. |
| Finish quality | Clean air prevents contamination of the sprayed material. |
| Reduced downtime | Preventive maintenance avoids unexpected air system failures. |

Air filter condition directly impacts sprayer performance. Replace filters when you observe these indicators or according to the manufacturer's recommended service intervals:
Noticeable decrease in air pressure or volume at the spray gun.
Filters appear dark, saturated, or loaded with debris/moisture.
Irregular atomization or pattern caused by fluctuating air supply.
