The Domnick Hunter K009AAR is an AAR-grade (0.01-micron oil and water removal) filter element from the Domnick Hunter brand of compressed air precision filters in the UK. It is compatible with the K009 series filter body and is primarily used for the efficient removal of oil mist, water droplets, and solid particles from compressed air (with a precision of up to 0.01 μm).
Model Meaning: K009 indicates the filter element size/interface series; AAR stands for "Advanced Air Removal," with a filtration precision of 0.01 microns and residual oil mist ≤0.01 mg/m³ (approximately 0.01 ppm).
Typical Applications: Used in food, pharmaceutical, electronics, and pneumatic instrumentation industries where high compressed air cleanliness is required. It is often placed after an AO-grade (1 μm) filter.
Note: K009AAR, K009AA, and K009AX all belong to the 0.01 μm class, but AAR specifically refers to a filter with a glass fiber oil removal element and a coagulation structure (non-activated carbon), and does not remove gaseous odors; for odor removal, choose ACS (containing activated carbon).
Current Status: This model is an "older" naming (K009AAR). Newer models may be labeled 009AAR (without the leading K), but their physical compatibility is the same.
