An air breather filter is a device that prevents airborne contaminants like dust, dirt, and moisture from entering a system, most commonly a hydraulic or lubricating oil reservoir. It functions by allowing the system to “breathe” clean air, which is crucial for maintaining system integrity as fluid levels change. These filters protect sensitive components, improve system efficiency, reduce maintenance costs, and extend equipment lifespan.
Micron rating: This measures the filter’s ability to trap particles.
Flow rate: The volume of air that can pass through the filter.
Connection type: How the filter is physically attached to the tank or system.
Materials: The components of the filter.
Housing: Durable materials like nylon, steel, or epoxy-coated steel.
Filter media: Typically a pleated paper or a synthetic material, such as phenolic resin-impregnated paper or expanded polyurethane foam.
Operating temperature range: The temperature range in which the filter will function correctly.
