Ingersoll-Rand 24241937 Filter Core for Screw Air Compressor

A Filter Core is the essential, replaceable inner component of a filtration system that performs the critical task of physically separating contaminants from a fluid (liquid or gas). It is the consumable element that traps and retains unwanted particles while allowing clean media to pass through. Think of it as the "heart" of the filter housing—while the housing is permanent, the core is replaced to maintain system performance and fluid cleanliness.

The primary function of a filter core is to protect downstream components and ensure fluid integrity. Its specific purposes include:

• Contaminant Removal: Capturing and holding particulate matter (dirt, metal shavings, rust, soot) from fluids
• Component Protection: Safeguarding sensitive and expensive components like pumps, valves, actuators, and nozzles from wear, clogging, and damage caused by abrasion
• Fluid Quality Maintenance: Preserving the chemical properties and cleanliness of hydraulic oil, fuel, coolant, air, or process gases
• System Efficiency: Maintaining optimal system performance by preventing pressure drops and flow restrictions caused by built-up contamination
• Water Separation: Certain filter cores (coalescing or absorbent types) are designed to remove water from fuel or oil

Filter cores work through a combination of physical mechanisms:

1. Surface Filtration: A membrane or wire mesh on the surface of the core captures particles larger than its pore size. This is common in sieve-type filters.
2. Depth Filtration: The fluid passes through a thick porous media (e.g., resin-impregnated cellulose, fiberglass, or sintered metal). Contaminants are trapped throughout the entire depth of the media via adsorption (sticking to the media), impingement (directly hitting fibers), or inertial forces. This allows for higher dirt holding capacity.
3. Adsorption: Some media (like activated carbon) chemically attract and hold certain dissolved contaminants.

The filter core is housed in a pressure-rated vessel. As contaminated fluid enters, it flows from the outside of the core inward. Contaminants are trapped on the outer surface or within the media matrix, and clean fluid exits through the inner core.

• Filtration Rating: Nominal (e.g., 10 micron) and Absolute (e.g., 3 micron) micron ratings.
• Beta Ratio (βx): Measure of efficiency (e.g., β₅ = 1000 means 99.9% of particles 5µm and larger are captured).
• Dirt Holding Capacity: Grams of standard test contaminant held at a specific pressure drop.
• Collapse/Burst Pressure: The maximum pressure differential the core can withstand.
• Media Material: Cellulose, Microglass, Synthetic (e.g., polyester, polypropylene), Sintered Metal, Wire Mesh.
• End Cap Material: Steel, plastic, or composite; compatible with various fluids.
• Seals: Buna-N, Viton, EPDM, or Silicone O-rings for leak-free operation.
