Introduction
This manual provides essential information for the proper use, maintenance, and troubleshooting of the DeVilbiss 130534 Ct 30 Plus Tune-up Kit. This kit is designed to be a cost-effective and convenient solution for maintaining your equipment, ensuring optimal performance and longevity.
Product Overview
The DeVilbiss 130534 Ct 30 Plus Tune-up Kit includes critical components for air filtration and humidity indication. The kit typically contains a DC30 desiccant cartridge water filter element, a coalescing filter element, and a humidity indicator.

The desiccant cartridge is crucial for removing moisture from compressed air, while the coalescing filter element removes oil aerosols and fine particles. The humidity indicator provides a visual cue regarding the saturation level of the desiccant, indicating when replacement is necessary.
Setup and Installation
Before beginning installation, ensure that the air supply to the system is completely shut off and depressurized. Refer to your specific air system's manual for detailed instructions on accessing the filter housing.
- Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, during installation.
- Depressurize System: Locate the air supply shut-off valve and turn it off. Bleed any remaining pressure from the system before proceeding.
- Access Filter Housing: Open the filter housing according to your equipment's instructions. This may involve unscrewing a bowl or releasing clamps.
- Remove Old Components: Carefully remove the old desiccant cartridge, coalescing filter element, and humidity indicator. Dispose of them according to local regulations.
- Install New Components:
- Insert the new DC30 desiccant cartridge into its designated slot. Ensure it is seated correctly.
- Install the new coalescing filter element. Verify that any O-rings are properly positioned to ensure a tight seal.
- Place the new humidity indicator in its designated viewing port or slot.
- Secure Housing: Close and secure the filter housing, ensuring all seals are intact and tightened appropriately to prevent air leaks.
- Restore Air Supply: Slowly open the air supply valve, allowing the system to repressurize. Check for any leaks around the filter housing.
Operating Principles
Once installed, the tune-up kit components work passively to purify the compressed air. The desiccant absorbs moisture, while the coalescing filter captures oil and particulate matter. The humidity indicator changes color to signal when the desiccant has reached its saturation point and needs replacement.
No specific operational steps are required for the kit itself beyond proper installation. The kit functions as an integral part of your air treatment system.
Maintenance
Regular maintenance of the DeVilbiss 130534 Ct 30 Plus Tune-up Kit is essential for optimal performance of your air system. The primary maintenance task is the timely replacement of the desiccant cartridge and filter elements.
Replacement Schedule:
- Desiccant Cartridge: Replace when the humidity indicator changes color, typically from blue to pink, or as recommended by your equipment manufacturer. The frequency depends on air usage and ambient humidity.
- Coalescing Filter Element: Replace every 6-12 months, or sooner if a significant pressure drop is observed across the filter, or if oil contamination is detected downstream.
- Humidity Indicator: Replace with the desiccant cartridge, or if it becomes damaged or unreadable.
Always use genuine DeVilbiss replacement parts to ensure compatibility and performance.
Troubleshooting
This section addresses common issues related to air quality and filter performance.
| Problem | Possible Cause | Solution |
|---|---|---|
| Moisture in air line (despite filter) | Desiccant cartridge saturated; filter housing leak; incorrect installation. | Replace desiccant cartridge; check and tighten all connections; re-install components ensuring proper seating and seals. |
| Oil or particles in air line | Coalescing filter element saturated or damaged; bypass in system. | Replace coalescing filter element; inspect system for bypasses or damaged lines. |
| Humidity indicator not changing color | Indicator faulty; desiccant not absorbing moisture (rare). | Replace humidity indicator; ensure desiccant cartridge is new and properly installed. |
| Reduced air flow/pressure drop | Filter elements clogged. | Replace both desiccant and coalescing filter elements. |
If issues persist after following these steps, contact DeVilbiss customer support or a qualified technician.
