During air compression, the process generates a significant amount of condensate mixed with compressor lubricant. Oil/water separators within industrial compressed air systems serve to keep this carryover-containing condensate from finding its way down a drain and creating environmental concerns when it leaches into local groundwater. Separating and properly disposing of this oil and particulate matter is required by various local clean air standards and EPA regulations to protect the environment.

At Energy Machinery, Inc., we serve clients throughout Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island with industry-leading air compressor oil/water separators. Learn more about the efficient, compliant products we have available for effective filtration.

Ideal Applications General industrial use and workshops Manufacturing plants and heavy-duty applications Harsh industrial environments and large-scale operations
Regulatory Compliance EPA and local regulations EPA and stringent compliance needs Meets or exceeds regulatory requirements

How Oil/Water Separators Work

The primary functions of these devices in compressed air systems are to:

  • 💧 Separate oils from water condensate
  • 🗑️Facilitate their disposal
  • 🧹Remove contaminants through multi-stage filtration prior to the water’s release into drainage systems

Key Benefits of Oil/Water Separators

Oil/water separators will lend your compressed air systems the following advantages:

  • 📜 Compliance with local and EPA regulations
  • 🌍 Oil discharge removal, reducing your impact on the environment
  • 🔧 Extended system life cycle
  • ⏳ Minimal unscheduled downtime
  • 💰 Cost-effectiveness of condensate removal (compared to using a waste hauler)

What Are the Disadvantages of Oil/Water Separators?

While these separators come with an array of benefits, the following are some potential drawbacks:

  • Maintenance requirements. Oil/water separator filters need frequent cleaning and periodic replacement for the devices to continue operating efficiently.
  • Incomplete separation. Not all separators can achieve fully oil-free water, leaving a trace of oil behind.
  • Specialty needs. If you have to separate synthetic oils, this may necessitate purchasing a specialized separator.
  • Initial cost. Certain high-capacity separators come at a premium, requiring a larger investment upfront.

Selecting a high-quality separator from a trusted supplier, however, can minimize these challenges. You can also try oil-free air compressors for hassle-free operations.

How to Size an Oil/Water Separator for an Air Compressor

When selecting a water/oil separator for air compressor applications, first consider the following factors:

Lubricant Type

Lubricant type. As each separator variety filters out a different type of oil, ensure that you choose a separator that’s compatible with your lubricant type.

Separator Type

Separator type. Based on your system, choose from activated carbon, coalescing, or gravity-based filtration.

Compressor Flow Rate

Compressor flow rate. In cubic feet per minute (CFM), identify the necessary amount of condensate your separator will need to process.

Operating Temperature and Pressure

Operating temperature and pressure. Be aware that high heat and pressure can negatively impact a separator’s efficiency and performance.

Drainage and Regulatory Requirements

Drainage and regulatory requirements. Your device should support EPA-compliant water disposal for your system.
