The Domnick Hunter K017AA is a precision compressed air filter from the British brand Domnick Hunter (now part of Parker Hannifin).
Filtration accuracy: 0.01 microns (μm). This is its most critical specification, classifying it as a "high-efficiency" or "activated carbon/oil vapor removal" pre-filter or equivalent high-precision filter.
Main functions: Filters solid particles, liquid water, oil mist, and some oil vapor from compressed air. It effectively protects downstream equipment with extremely high air quality requirements (such as pneumatic tools, instruments, and painting equipment).
Technical features: Employs deep-bed pleated technology, increasing the filtration area by approximately 450% compared to traditional filter elements, thereby reducing pressure drop and extending service life.
Applications: Typically installed after a refrigerated dryer as a main filter, or as a critical filtration element in processes requiring extremely high air cleanliness.
Material and Structure: The filter media is usually made of glass fiber or special synthetic fiber, which has the characteristics of corrosion resistance, strong dirt holding capacity, and no fiber shedding.
