1. Product Overview
The MAKO AIRTEK Oil Separator, Model DA 1282 DA1282, is a critical component designed for Sullair air compressors. Its primary function is to efficiently separate oil from the compressed air stream, ensuring clean air output and protecting downstream equipment. This direct replacement part is manufactured using high-quality raw materials to meet original manufacturing standards, offering reliable performance and contributing to reduced maintenance costs.
Proper installation and regular maintenance are essential for the optimal performance and longevity of your air compressor system. Please read this manual thoroughly before installation or operation.
2. Safety Information
Always observe the following safety precautions to prevent injury or damage to equipment:
- Ensure the air compressor system is completely depressurized and powered off before attempting any installation, maintenance, or inspection.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Only qualified personnel should perform installation and maintenance procedures.
- Refer to the Sullair compressor's original manual for specific safety guidelines related to your compressor model.
- Do not modify the oil separator or use it for purposes other than its intended function.
- Dispose of used oil and separator elements according to local environmental regulations.
3. Installation Instructions
This section outlines the general steps for installing the MAKO AIRTEK Oil Separator. Always consult your specific Sullair compressor service manual for detailed, model-specific instructions.
- Preparation: Ensure the compressor is shut down, locked out, and depressurized. Allow the system to cool down.
- Access: Locate the existing oil separator housing. This may require removing access panels.
- Drain Oil: Carefully drain any residual oil from the separator housing.
- Remove Old Separator: Disconnect any associated piping or sensors. Remove the old oil separator element. Note its orientation for correct installation of the new part.
- Clean Housing: Thoroughly clean the separator housing and sealing surfaces to remove any debris or old gasket material.
- Install New Separator: Carefully insert the new MAKO AIRTEK Oil Separator (Model DA 1282 DA1282) into the housing, ensuring proper seating and orientation.
- Replace Gaskets/Seals: Use new gaskets and seals as required to ensure an airtight and oil-tight seal.
- Reconnect: Reconnect all piping, sensors, and access panels.
- Refill Oil: Refill the compressor with the recommended type and amount of compressor oil.
- Leak Check: Start the compressor and carefully check for any air or oil leaks. Monitor pressure and temperature readings.

4. Operation Guidelines
Once installed, the oil separator operates automatically as part of the compressor system. Key operational considerations include:
- Monitor Pressure Drop: A significant increase in pressure drop across the oil separator indicates that the element is becoming clogged and requires replacement. Refer to your compressor's manual for acceptable pressure differential limits.
- Oil Carryover: Excessive oil in the compressed air output (oil carryover) suggests a failing oil separator element or other system issues.
- System Performance: Ensure the compressor operates within its specified temperature and pressure ranges.
5. Maintenance
Regular maintenance is crucial for the efficiency and lifespan of your air compressor and the oil separator.
5.1. Replacement Schedule
The oil separator element should be replaced according to the compressor manufacturer's recommendations, typically based on operating hours or a fixed time interval (e.g., every 2000-4000 hours or annually), whichever comes first. Operating conditions (e.g., dusty environments) may necessitate more frequent replacement.
5.2. Inspection
- Periodically inspect the oil separator housing and connections for any signs of leaks or damage.
- Check the oil level in the compressor regularly and ensure it is within the recommended range.
