Ingersoll-Rand 39303219 Small Hole Oil Return Filter for Screw Air Compressor

An Oil Filter is a critical component in any lubrication or hydraulic system, designed to remove contaminants--such as dirt, metal particles, soot, and carbon deposits--from oil before it circulates through an engine, compressor, turbine, or hydraulic unit. By continuously cleaning the oil, it prevents abrasive wear, protects sensitive components, and ensures optimal performance and an extended service life for both the fluid and the machinery it protects.

• Advanced Filtration Media: Utilizes a blend of cellulose, synthetic fibers, and glass to create a high-density matrix that captures a high percentage of harmful contaminants, often as small as 10-20 microns, providing superior protection against wear.
• High Dirt Holding Capacity: Engineered with deep pleats and optimized media area to retain a significant amount of contaminant before reaching capacity. This extends service intervals and reduces maintenance frequency and costs.
• Robust Construction for Reliability:
  • Casing: Made from heavy-gauge steel or durable composite materials to withstand high system pressures and vibration without failure.
  • End Caps: Polymer or steel caps bonded to the media to prevent bypass and ensure all oil is filtered.
  • Gasket: A precision-molded, oil-resistant gasket (typically nitrile) ensures a perfect, leak-free seal.
• Anti-Drainback Valve (where applicable): A silicone valve prevents oil from draining out of the filter when the engine is off. This ensures instant oil pressure upon startup, protecting critical components from dry running and wear.
• Bypass Valve: A safety feature that allows unfiltered oil to bypass the element if it becomes clogged (e.g., in cold weather with viscous oil) or excessively dirty, ensuring a continuous flow of oil to the engine even in a compromised state.
• Optimal Flow & Pressure Drop: Designed to provide excellent filtration without restricting oil flow, maintaining proper lubrication pressure and ensuring maximum engine efficiency.

1. Oil Entry: Pressurized, unfiltered oil from the pump enters the filter through the perimeter ports.
2. Filtration: The oil is forced under pressure through the microporous pleated media. Contaminants are trapped within the fibers.
3. Clean Oil Exit: The cleaned oil flows through the center tube and out the central outlet port, returning to the engine for lubrication.
4. Safety Bypass: If the media becomes clogged, the resulting pressure differential opens the bypass valve, ensuring oil flow continues (unfiltered) to protect the engine from oil starvation.

Our oil filters are essential for a vast range of equipment:

• Automotive & Transportation: Gasoline and diesel engines in cars, trucks, buses, and heavy-duty equipment.
• Industrial Machinery: Hydraulic systems, gearboxes, compressors, turbines, and power generators.
• Marine: Main propulsion engines and auxiliary power units on ships and boats.
• Agriculture: Tractors, combines, and other farm machinery.
• Construction & Mining: Excavators, bulldozers, and other off-highway equipment.

• Superior Engine Protection: Our filters are engineered to capture more harmful contaminants than standard filters, significantly reducing engine wear and extending its operational life.
• OEM Quality & Beyond: Manufactured to meet or exceed Original Equipment Manufacturer (OEM) specifications for fit, form, and function, ensuring perfect compatibility and performance.
• Rigorous Testing: Each filter design is subjected to extensive validation for burst strength, efficiency, capacity, and fatigue resistance to ensure reliability in the most demanding conditions.
• Thermal and Mechanical Durability: Constructed to perform reliably under extreme temperatures and constant vibration, guaranteeing integrity throughout the service interval.
• Total Value: While initial cost is a factor, our high-quality filters protect multi-thousand-dollar assets, reduce downtime, and extend oil life, providing a significantly lower total cost of ownership.
