Essential Components and Maintenance for Oil-Injected Screw Compressors

Oil-injected screw compressors are reliable machines, but their performance depends on key components working together and regular servicing. These components include the oil filter, air filter, oil-air separator, and compressor oil.

Key Components and Their Importance

Air Filter

• Purpose: Filters airborne particles from intake air to prevent wear and clogging.

• Key Features: Durable, pleated material ensures high filtration and airflow efficiency.

• Tip: Regularly clean or replace filters to avoid restricted airflow and increased energy use.

Oil Filter

• Purpose: Removes contaminants (dirt, sand, rust) from the oil to protect bearings and prevent damage.

• Key Features: Includes a pleated paper element for maximum filtration and a bypass valve to maintain oil flow if the filter clogs or the oil is too cold.

• Tip: Use filters specifically designed for compressors, not automotive filters.

Oil-Air Separator

• Purpose: Separates oil from compressed air, reducing oil carryover, protecting downstream equipment, and recycling oil back to the compressor.

• Key Features: Built to handle high pressures with efficient multi-layered filtration media.

• Tip: Replace regularly to prevent performance drops or excessive oil consumption.

Compressor Oil

• Purpose: Lubricates, cools, and seals the system while protecting components from wear.

• Key Features: High-temperature stability and additives to enhance performance and longevity.

• Tip: Use compressor-specific oil and monitor regularly for contamination or degradation.

Service Intervals for Optimal Maintenance

2000, 6000, etc. Hour Services

Replace:

1. Air Filter: Maintains clean airflow and prevents debris from entering the system.

2. Oil Filter: Ensures oil remains free of contaminants.

3. Oil: Restores lubrication, cooling, and sealing properties.

4000, 8000, etc. Hour Services

Replace:

1. Air Filter: Maintains clean airflow and prevents debris from entering the system.

2. Oil Filter: Ensures oil remains free of contaminants.

3. Oil-Air Separator: Prevents oil carryover and ensures system efficiency.

4. Oil: Restores lubrication, cooling, and sealing properties.

Why Regular Maintenance Matters

• Prevention: Avoids costly breakdowns by addressing wear early.

• Efficiency: Keeps the system running smoothly, reducing energy use.

• Longevity: Extends the life of the compressor and its components.

By adhering to these service schedules and using quality parts, you can ensure reliable, efficient operation and long-term cost savings for your compressor system.
